            This program demonstrates how to interact with AWS Key Management using the AWS SDK for Java (v2).
            The AWS Key Management Service (KMS) is a secure and highly available service that allows you to create 
            and manage AWS KMS keys and control their use across a wide range of AWS services and applications. 
            KMS provides a centralized and unified approach to managing encryption keys, making it easier to meet your 
            data protection and regulatory compliance requirements.
                        
            This Basics scenario creates two key types:
                        
            - A symmetric encryption key is used to encrypt and decrypt data.
            - An asymmetric key used to digitally sign data.

Welcome to the AWS Key Management Service SDK Basics scenario.
        
This program demonstrates how to interact with AWS Key Management Service using the AWS SDK for PHP (v3).
The AWS Key Management Service (KMS) is a secure and highly available service that allows you to create
and manage AWS KMS keys and control their use across a wide range of AWS services and applications.
KMS provides a centralized and unified approach to managing encryption keys, making it easier to meet your
data protection and regulatory compliance requirements.

This KMS Basics scenario creates two key types:
- A symmetric encryption key is used to encrypt and decrypt data.
- An asymmetric key used to digitally sign data.

Let's get started...\n

The AWS Key Management Service (KMS) is a secure and highly available service that allows you to create

KMS provides a centralized and unified approach to managing encryption keys, making it easier to meet your
data protection and regulatory compliance requirements.

This Basics scenario creates two key types:

- A symmetric encryption key is used to encrypt and decrypt data.
- An asymmetric key used to digitally sign data.

#### [ CLI ]

**AWS CLI**  
**Untuk membuat alias untuk kunci KMS**  
`create-alias`Perintah berikut membuat alias bernama `example-alias` untuk kunci KMS diidentifikasi oleh ID kunci. `1234abcd-12ab-34cd-56ef-1234567890ab`  
Nama alias harus dimulai dengan`alias/`. Jangan gunakan nama alias yang dimulai dengan`alias/aws`; ini dicadangkan untuk digunakan oleh AWS.  

```
aws kms create-alias \
    --alias-name alias/example-alias \
    --target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Perintah ini tidak mengembalikan output apa pun. Untuk melihat alias baru, gunakan `list-aliases` perintah.

**AWS CLI**  
**Untuk membuat hibah**  
`create-grant`Contoh berikut membuat hibah yang memungkinkan `exampleUser` pengguna untuk menggunakan `decrypt` perintah pada kunci KMS `1234abcd-12ab-34cd-56ef-1234567890ab` contoh. Kepala sekolah yang pensiun adalah `adminRole` perannya. Hibah menggunakan batasan `EncryptionContextSubset` hibah untuk mengizinkan izin ini hanya jika konteks enkripsi dalam `decrypt` permintaan menyertakan pasangan nilai `"Department": "IT"` kunci.  

```

    --operations Decrypt \
    --constraints EncryptionContextSubset={Department=IT} \

#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk membuat kunci KMS yang dikelola pelanggan di AWS KMS**  
`create-key`Contoh berikut membuat kunci KMS enkripsi simetris.  
Untuk membuat kunci KMS dasar, kunci enkripsi simetris, Anda tidak perlu menentukan parameter apa pun. Nilai default untuk parameter tersebut membuat kunci enkripsi simetris.  
Karena perintah ini tidak menentukan kebijakan kunci, kunci KMS mendapatkan [kebijakan kunci default untuk kunci](https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html#key-policy-default) KMS yang dibuat secara terprogram. Untuk melihat kebijakan kunci, gunakan `get-key-policy` perintah. Untuk mengubah kebijakan kunci, gunakan `put-key-policy` perintah.  

```
aws kms create-key
```
`create-key`Perintah mengembalikan metadata kunci, termasuk ID kunci dan ARN dari kunci KMS baru. Anda dapat menggunakan nilai-nilai ini untuk mengidentifikasi kunci KMS dalam operasi AWS KMS lainnya. Outputnya tidak termasuk tag. Untuk melihat tag untuk kunci KMS, gunakan tombol. `list-resource-tags command`  
Output:  

```
{
    "KeyMetadata": {
        "AWSAccountId": "111122223333",
        "Arn": "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",

        "EncryptionAlgorithms": [
            "SYMMETRIC_DEFAULT"
        ]
    }
}

Catatan: `create-key` Perintah tidak memungkinkan Anda menentukan alias, Untuk membuat alias untuk kunci KMS baru, gunakan perintah. `create-alias`  
Untuk informasi selengkapnya, lihat [Membuat AWS kunci](https://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html) *di Panduan Pengembang Layanan Manajemen Kunci*.  
**Contoh 2: Untuk membuat kunci KMS RSA asimetris untuk enkripsi dan dekripsi**  
`create-key`Contoh berikut membuat kunci KMS yang berisi asimetris RSA key pair untuk enkripsi dan dekripsi. Spesifikasi kunci dan penggunaan kunci tidak dapat diubah setelah kunci dibuat. :  

```
aws kms create-key \
   --key-spec RSA_4096 \

# Gunakan `Decrypt` dengan AWS SDK atau CLI

Contoh kode berikut menunjukkan cara menggunakan`Decrypt`.

Contoh tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Anda dapat melihat tindakan ini dalam konteks dalam contoh kode berikut:

#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk mendekripsi pesan terenkripsi dengan kunci KMS simetris (Linux dan macOS)**  
Contoh `decrypt` perintah berikut menunjukkan cara yang disarankan untuk mendekripsi data dengan CLI. AWS Versi ini menunjukkan cara mendekripsi data di bawah kunci KMS simetris.  
Berikan ciphertext dalam file.Dalam nilai `--ciphertext-blob` parameter, gunakan `fileb://` awalan, yang memberitahu CLI untuk membaca data dari file biner. Jika file tidak ada di direktori saat ini, ketik path lengkap ke file. Untuk informasi lebih lanjut tentang membaca nilai parameter AWS CLI dari file, lihat Memuat parameter AWS CLI dari file < https://docs.aws.amazon.com/cli/ latest/userguide/cli - usage-parameters-file .html> di *Panduan Pengguna Antarmuka Baris AWS Perintah dan Praktik Terbaik untuk Parameter File Lokal< https://aws.amazon.com/blogs/ pengembang/ best-practices-for-local -file-parameters/> di *Blog Alat Baris* Perintah*. Tentukan kunci KMS untuk mendekripsi ciphertext. Parameter tidak diperlukan saat AWS mendekripsi dengan kunci KMS simetris. `--key-id` AWS KMS bisa mendapatkan ID kunci dari kunci KMS yang digunakan untuk mengenkripsi data dari metadata dalam ciphertext. Tetapi selalu merupakan praktik terbaik untuk menentukan kunci KMS yang Anda gunakan. Praktek ini memastikan bahwa Anda menggunakan kunci KMS yang Anda inginkan, dan mencegah Anda dari secara tidak sengaja mendekripsi ciphertext menggunakan kunci KMS yang tidak Anda percayai. Minta output plaintext sebagai nilai teks.Parameter `--query` memberitahu CLI untuk mendapatkan hanya nilai bidang dari output. `Plaintext` `--output`Parameter mengembalikan output sebagai text.base64-decode plaintext dan menyimpannya dalam file.Contoh berikut pipa (\$1) nilai `Plaintext` parameter ke utilitas Base64, yang menerjemahkan itu. Kemudian, itu mengalihkan (>) output yang diterjemahkan ke file. `ExamplePlaintext`  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda.  

```
aws kms decrypt \
    --ciphertext-blob fileb://ExampleEncryptedFile \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --output text \
    --query Plaintext | base64 \
    --decode > ExamplePlaintextFile
```
Perintah ini tidak menghasilkan output. Output dari `decrypt` perintah adalah base64-decoded dan disimpan dalam file.  
Untuk informasi selengkapnya, lihat [Mendekripsi](https://docs.aws.amazon.com/kms/latest/APIReference/API_Decrypt.html) di Referensi *API Layanan Manajemen AWS Kunci*.  
**Contoh 2: Untuk mendekripsi pesan terenkripsi dengan tombol KMS simetris (prompt perintah Windows)**  
Contoh berikut adalah sama dengan yang sebelumnya kecuali bahwa ia menggunakan `certutil` utilitas untuk Base64-decode data plaintext. Prosedur ini membutuhkan dua perintah, seperti yang ditunjukkan pada contoh berikut.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda.  

```
aws kms decrypt ^
    --ciphertext-blob fileb://ExampleEncryptedFile ^
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab ^
    --output text ^
    --query Plaintext > ExamplePlaintextFile.base64
```
Jalankan perintah `certutil`.  

```
certutil -decode ExamplePlaintextFile.base64 ExamplePlaintextFile
```
Output:  

```
Input Length = 18
Output Length = 12
CertUtil: -decode command completed successfully.
```
Untuk informasi selengkapnya, lihat [Mendekripsi](https://docs.aws.amazon.com/kms/latest/APIReference/API_Decrypt.html) di Referensi *API Layanan Manajemen AWS Kunci*.  
**Contoh 3: Untuk mendekripsi pesan terenkripsi dengan kunci KMS asimetris (Linux dan macOS)**  
Contoh `decrypt` perintah berikut menunjukkan cara mendekripsi data yang dienkripsi di bawah kunci KMS asimetris RSA.  
Saat menggunakan kunci KMS asimetris, `encryption-algorithm` parameter, yang menentukan algoritma yang digunakan untuk mengenkripsi plaintext, diperlukan.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda.  

```
aws kms decrypt \
    --ciphertext-blob fileb://ExampleEncryptedFile \
    --key-id 0987dcba-09fe-87dc-65ba-ab0987654321 \
    --encryption-algorithm RSAES_OAEP_SHA_256 \
    --output text \
    --query Plaintext | base64 \
    --decode > ExamplePlaintextFile
```
Perintah ini tidak menghasilkan output. Output dari `decrypt` perintah adalah base64-decoded dan disimpan dalam file.  
Untuk informasi selengkapnya, lihat [Kunci asimetris di AWS KMS](https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html) di Panduan *Pengembang Layanan Manajemen AWS Kunci*.

#### [ CLI ]

**AWS CLI**  
**Untuk mengaktifkan kunci KMS**  
`enable-key`Contoh berikut memungkinkan kunci yang dikelola pelanggan. Anda dapat menggunakan perintah seperti ini untuk mengaktifkan kunci KMS yang Anda nonaktifkan sementara dengan menggunakan `disable-key` perintah. Anda juga dapat menggunakannya untuk mengaktifkan kunci KMS yang dinonaktifkan karena dijadwalkan untuk dihapus dan penghapusan dibatalkan.  
Untuk menentukan kunci KMS, gunakan `key-id` parameter. Contoh ini menggunakan nilai ID kunci, tetapi Anda dapat menggunakan ID kunci atau nilai ARN kunci dalam perintah ini.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan yang valid.  

```
aws kms enable-key \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Perintah ini tidak menghasilkan output. Untuk memverifikasi bahwa kunci KMS diaktifkan, gunakan `describe-key` perintah. Lihat nilai `KeyState` dan `Enabled` bidang dalam `describe-key` output.  
Untuk informasi selengkapnya, lihat [Mengaktifkan dan Menonaktifkan Kunci di Panduan](https://docs.aws.amazon.com/kms/latest/developerguide/enabling-keys.html) Pengembang *Layanan Manajemen AWS Kunci*.

# Gunakan `EnableKeyRotation` dengan AWS SDK atau CLI
<a name="kms_example_kms_EnableKeyRotation_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`EnableKeyRotation`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk mengaktifkan rotasi otomatis tombol KMS**  
`enable-key-rotation`Contoh berikut memungkinkan rotasi otomatis kunci KMS yang dikelola pelanggan dengan periode rotasi 180 hari. Kunci KMS akan diputar satu tahun (perkiraan 365 hari) dari tanggal perintah ini selesai dan setiap tahun setelahnya.  
`--key-id`Parameter mengidentifikasi kunci KMS. Contoh ini menggunakan nilai ARN kunci, tetapi Anda dapat menggunakan ID kunci atau ARN dari kunci `--rotation-period-in-days` KMS.Parameter menentukan jumlah hari antara setiap tanggal rotasi. Tentukan nilai antara 90 dan 2560 hari. Jika tidak ada nilai yang ditentukan, nilai defaultnya adalah 365 hari.  

```
aws kms enable-key-rotation \
    --key-id arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab \
    --rotation-period-in-days 180
```
Perintah ini tidak menghasilkan output. Untuk memverifikasi bahwa kunci KMS diaktifkan, gunakan `get-key-rotation-status` perintah.

# Gunakan `Encrypt` dengan AWS SDK atau CLI

Contoh tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Anda dapat melihat tindakan ini dalam konteks dalam contoh kode berikut: 
+  [Pelajari dasar-dasarnya](kms_example_kms_Scenario_Basics_section.md) 

------
#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk mengenkripsi isi file di Linux atau macOS**  
`encrypt`Perintah berikut menunjukkan cara yang disarankan untuk mengenkripsi data dengan CLI AWS .  

```
aws kms encrypt \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --plaintext fileb://ExamplePlaintextFile \
    --output text \
    --query CiphertextBlob | base64 \
    --decode > ExampleEncryptedFile
```
Perintah tersebut melakukan beberapa hal:  
Menggunakan `--plaintext` parameter untuk menunjukkan data yang akan dienkripsi. Nilai parameter ini harus Base64-encode.Nilai `plaintext` parameter harus base64-dikodekan, atau Anda harus menggunakan awalan`fileb://`, yang memberitahu AWS CLI untuk membaca data biner dari file.Jika file tidak dalam direktori saat ini, ketik path lengkap ke file. Misalnya: `fileb:///var/tmp/ExamplePlaintextFile` atau `fileb://C:\Temp\ExamplePlaintextFile`. [Untuk informasi lebih lanjut tentang membaca nilai parameter AWS CLI dari file, lihat [Memuat Parameter dari File](https://docs.aws.amazon.com/cli/latest/userguide/cli-using-param.html#cli-using-param-file) di *Panduan Pengguna Antarmuka Baris AWS Perintah* dan [Praktik Terbaik untuk Parameter File Lokal](https://blogs.aws.amazon.com/cli/post/TxLWWN1O25V1HE/Best-Practices-for-Local-File-Parameters) di Blog Alat Baris AWS Perintah.Menggunakan `--output` dan `--query` parameter untuk mengontrol output perintah.Parameter ini mengekstrak data terenkripsi, yang disebut *ciphertext*, dari output perintah.Untuk informasi lebih lanjut tentang mengontrol output, lihat Mengontrol Perintah Output](https://docs.aws.amazon.com/cli/latest/userguide/controlling-output.html) dalam *Panduan Pengguna Antarmuka Baris AWS Perintah.Menggunakan* `base64` utilitas untuk memecahkan kode output yang diekstraksi ke dalam data biner.Ciphertext yang dikembalikan oleh perintah yang berhasil adalah teks yang dikodekan base64. `encrypt` Anda harus memecahkan kode teks ini sebelum Anda dapat menggunakan AWS CLI untuk mendekripsi itu.Menyimpan ciphertext biner ke file.Bagian terakhir dari perintah `> ExampleEncryptedFile` () menyimpan ciphertext biner ke file untuk membuat dekripsi lebih mudah. Untuk contoh perintah yang menggunakan AWS CLI untuk mendekripsi data, lihat contoh dekripsi.  
**Contoh 2: Menggunakan AWS CLI untuk mengenkripsi data pada Windows**  
Contoh ini sama dengan yang sebelumnya, kecuali bahwa ia menggunakan `certutil` alat sebagai gantinya`base64`. Prosedur ini membutuhkan dua perintah, seperti yang ditunjukkan pada contoh berikut.  

```
aws kms encrypt \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --plaintext fileb://ExamplePlaintextFile \
    --output text \
    --query CiphertextBlob > C:\Temp\ExampleEncryptedFile.base64

certutil -decode C:\Temp\ExampleEncryptedFile.base64 C:\Temp\ExampleEncryptedFile
```
**Contoh 3: Mengenkripsi dengan tombol KMS asimetris**  
`encrypt`Perintah berikut menunjukkan cara mengenkripsi plaintext dengan kunci KMS asimetris. parameter `--encryption-algorithm` diperlukan. Seperti pada semua perintah `encrypt` CLI, `plaintext` parameter harus dikodekan base64, atau Anda harus menggunakan `fileb://` awalan, yang memberi tahu AWS CLI untuk membaca data biner dari file.  

```
aws kms encrypt \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --encryption-algorithm RSAES_OAEP_SHA_256 \
    --plaintext fileb://ExamplePlaintextFile \
    --output text \
    --query CiphertextBlob | base64 \
    --decode > ExampleEncryptedFile
```
Perintah ini tidak menghasilkan output.

# Gunakan `GenerateDataKey` dengan AWS SDK atau CLI
<a name="kms_example_kms_GenerateDataKey_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`GenerateDataKey`.

------
#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk menghasilkan kunci data simetris 256-bit**  
`generate-data-key`Contoh berikut meminta kunci data simetris 256-bit untuk digunakan di luar. AWS Perintah mengembalikan kunci data plaintext untuk segera digunakan dan dihapus, dan salinan kunci data yang dienkripsi di bawah kunci KMS yang ditentukan. Anda dapat dengan aman menyimpan kunci data terenkripsi dengan data terenkripsi.  
Untuk meminta kunci data 256-bit, gunakan `key-spec` parameter dengan nilai. `AES_256` Untuk meminta kunci data 128-bit, gunakan `key-spec` parameter dengan nilai. `AES_128` Untuk semua panjang kunci data lainnya, gunakan `number-of-bytes` parameter.  
Kunci KMS yang Anda tentukan harus berupa kunci KMS enkripsi simetris, yaitu kunci KMS dengan nilai spesifikasi kunci SYMMETRIC\$1DEFAULT.  

```
aws kms generate-data-key \
    --key-id alias/ExampleAlias \
    --key-spec AES_256
```
Output:  

```

`generate-data-key`Contoh berikut meminta kunci data simetris 512-bit untuk enkripsi dan dekripsi. Perintah mengembalikan kunci data plaintext untuk segera digunakan dan dihapus, dan salinan kunci data yang dienkripsi di bawah kunci KMS yang ditentukan. Anda dapat dengan aman menyimpan kunci data terenkripsi dengan data terenkripsi.  
Untuk meminta panjang kunci selain 128 atau 256 bit, gunakan `number-of-bytes` parameter. Untuk meminta kunci data 512-bit, contoh berikut menggunakan `number-of-bytes` parameter dengan nilai 64 (byte).  
Kunci KMS yang Anda tentukan harus berupa kunci KMS enkripsi simetris, yaitu kunci KMS dengan nilai spesifikasi kunci SYMMETRIC\$1DEFAULT.

# Gunakan `GenerateRandom` dengan AWS SDK atau CLI
<a name="kms_example_kms_GenerateRandom_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`GenerateRandom`.

------
#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk menghasilkan string byte acak 256-bit (Linux atau macOS)**  
`generate-random`Contoh berikut menghasilkan 256-bit (32-byte), string byte acak yang dikodekan base64. Contoh menerjemahkan string byte dan menyimpannya dalam file acak.  
Ketika Anda menjalankan perintah ini, Anda harus menggunakan `number-of-bytes` parameter untuk menentukan panjang nilai acak dalam byte.  
Anda tidak menentukan kunci KMS ketika Anda menjalankan perintah ini. String byte acak tidak terkait dengan kunci KMS apa pun.  
Secara default, AWS KMS menghasilkan nomor acak. Namun, jika Anda menentukan [penyimpanan kunci khusus](https://docs.aws.amazon.com/kms/latest/developerguide/custom-key-store-overview.html), string byte acak dihasilkan di klaster AWS CloudHSM yang terkait dengan penyimpanan kunci kustom.  
Contoh ini menggunakan parameter dan nilai berikut:  
Ini menggunakan `--number-of-bytes` parameter yang diperlukan dengan nilai `32` untuk meminta string 32-byte (256-bit). Ini menggunakan `--output` parameter dengan nilai untuk `text` mengarahkan AWS CLI untuk mengembalikan output sebagai teks, bukan JSON.Ini menggunakan untuk mengekstrak nilai `Plaintext` properti dari response.It pipa (\$1) output dari perintah `--query parameter` ke `base64` utilitas, yang menerjemahkan output yang diekstraksi.Ini menggunakan operator pengalihan (>) untuk menyimpan string byte yang diterjemahkan ke file. Ini menggunakan operator pengalihan (>) `ExampleRandom` untuk menyimpan ciphertext biner ke file.  

```
aws kms generate-random \
    --number-of-bytes 32 \
    --output text \
    --query Plaintext | base64 --decode > ExampleRandom
```

**Contoh 2: Untuk menghasilkan nomor acak 256-bit (Windows Command Prompt)**  
Contoh berikut menggunakan `generate-random` perintah untuk menghasilkan string byte acak 256-bit (32-byte) yang dikodekan base64. Contoh menerjemahkan string byte dan menyimpannya dalam file acak. Contoh ini sama dengan contoh sebelumnya, kecuali bahwa ia menggunakan `certutil` utilitas di Windows untuk base64-decode string byte acak sebelum menyimpannya dalam file.  
Pertama, buat string byte acak yang dikodekan base64 dan simpan dalam file sementara,. `ExampleRandom.base64`  

```
aws kms generate-random \
    --number-of-bytes 32 \
    --output text \
    --query Plaintext > ExampleRandom.base64
```
Karena output dari `generate-random` perintah disimpan dalam file, contoh ini tidak menghasilkan output.  
Sekarang gunakan `certutil -decode` perintah untuk memecahkan kode string byte yang dikodekan base64 dalam file. `ExampleRandom.base64` Kemudian, ia menyimpan string byte yang diterjemahkan dalam file. `ExampleRandom`  

```
certutil -decode ExampleRandom.base64 ExampleRandom
```
Output:  

```
Input Length = 18
Output Length = 12
CertUtil: -decode command completed successfully.

#### [ CLI ]

**AWS CLI**  
**Untuk menyalin kebijakan kunci dari satu kunci KMS ke kunci KMS lainnya**  
`get-key-policy`Contoh berikut mendapatkan kebijakan kunci dari satu kunci KMS dan menyimpannya dalam file teks. Kemudian, itu menggantikan kebijakan kunci KMS yang berbeda menggunakan file teks sebagai input kebijakan.  
Karena `--policy` parameter `put-key-policy` membutuhkan string, Anda harus menggunakan `--output text` opsi untuk mengembalikan output sebagai string teks bukan JSON.  

```
aws kms get-key-policy \
    --policy-name default \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \

#### [ CLI ]

**Contoh 1: Untuk mencantumkan semua alias di AWS akun dan Wilayah**  
Contoh berikut menggunakan `list-aliases` perintah untuk daftar semua alias di Wilayah default AWS akun. Outputnya mencakup alias yang terkait dengan kunci KMS AWS terkelola dan kunci KMS yang dikelola pelanggan.  

```
aws kms list-aliases
```
Output:  

```
{
    "Aliases": [
        {
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/testKey",
            "AliasName": "alias/testKey",
            "TargetKeyId": "1234abcd-12ab-34cd-56ef-1234567890ab"
        },
        {
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/FinanceDept",
            "AliasName": "alias/FinanceDept",
            "TargetKeyId": "0987dcba-09fe-87dc-65ba-ab0987654321"
        },
        {
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/aws/dynamodb",
            "AliasName": "alias/aws/dynamodb",
            "TargetKeyId": "1a2b3c4d-5e6f-1a2b-3c4d-5e6f1a2b3c4d"
        },
        {
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/aws/ebs",
            "AliasName": "alias/aws/ebs",
            "TargetKeyId": "0987ab65-43cd-21ef-09ab-87654321cdef"
        },
        ...
    ]
}
```
**Contoh 2: Untuk daftar semua alias untuk kunci KMS tertentu**  
Contoh berikut menggunakan `list-aliases` perintah dan `key-id` parameternya untuk daftar semua alias yang terkait dengan kunci KMS tertentu.  
Setiap alias dikaitkan dengan hanya satu kunci KMS, tetapi kunci KMS dapat memiliki beberapa alias. Perintah ini sangat berguna karena konsol AWS KMS hanya mencantumkan satu alias untuk setiap tombol KMS. Untuk menemukan semua alias untuk kunci KMS, Anda harus menggunakan perintah. `list-aliases`  
Contoh ini menggunakan ID kunci kunci KMS untuk `--key-id` parameter, tetapi Anda dapat menggunakan ID kunci, kunci ARN, nama alias, atau alias ARN dalam perintah ini.  

```
aws kms list-aliases --key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Output:  

```
{
    "Aliases": [
        {
            "TargetKeyId": "1234abcd-12ab-34cd-56ef-1234567890ab",
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/oregon-test-key",
            "AliasName": "alias/oregon-test-key"
        },
        {
            "TargetKeyId": "1234abcd-12ab-34cd-56ef-1234567890ab",
            "AliasArn": "arn:aws:kms:us-west-2:111122223333:alias/project121-test",

#### [ CLI ]

**AWS CLI**  
**Untuk melihat hibah pada kunci AWS KMS**  
`list-grants`Contoh berikut menampilkan semua hibah pada kunci KMS AWS terkelola yang ditentukan untuk Amazon DynamoDB di akun Anda. Hibah ini memungkinkan DynamoDB untuk menggunakan kunci KMS atas nama Anda untuk mengenkripsi tabel DynamoDB sebelum menulisnya ke disk. Anda dapat menggunakan perintah seperti ini untuk melihat hibah pada kunci KMS yang AWS dikelola dan kunci KMS yang dikelola pelanggan di AWS akun dan Wilayah.  
Perintah ini menggunakan `key-id` parameter dengan ID kunci untuk mengidentifikasi kunci KMS. Anda dapat menggunakan ID kunci atau kunci ARN untuk mengidentifikasi kunci KMS. Untuk mendapatkan ID kunci atau kunci ARN dari kunci KMS yang AWS dikelola, gunakan perintah or. `list-keys` `list-aliases`  

```
aws kms list-grants \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Output menunjukkan bahwa hibah memberikan izin Amazon DynamoDB untuk menggunakan kunci KMS untuk operasi kriptografi, dan memberikan izin untuk melihat detail tentang kunci KMS () dan untuk menghentikan hibah `DescribeKey` (). `RetireGrant` Batasan `EncryptionContextSubset` membatasi izin ini untuk permintaan yang menyertakan pasangan konteks enkripsi yang ditentukan. Akibatnya, izin dalam hibah hanya efektif pada akun tertentu dan tabel DynamoDB.

# Gunakan `ListKeyPolicies` dengan AWS SDK atau CLI

Contoh kode berikut menunjukkan cara menggunakan`ListKeyPolicies`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk mendapatkan nama kebijakan kunci untuk kunci KMS**  
`list-key-policies`Contoh berikut mendapatkan nama-nama kebijakan utama untuk kunci yang dikelola pelanggan di akun contoh dan Wilayah. Anda dapat menggunakan perintah ini untuk menemukan nama kebijakan kunci untuk kunci AWS terkelola dan kunci yang dikelola pelanggan.  
Karena satu-satunya nama kebijakan kunci yang valid adalah`default`, perintah ini tidak berguna.  
Untuk menentukan kunci KMS, gunakan `key-id` parameter. Contoh ini menggunakan nilai ID kunci, tetapi Anda dapat menggunakan ID kunci atau kunci ARN dalam perintah ini.  

```
aws kms list-key-policies \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab

# Gunakan `PutKeyPolicy` dengan AWS SDK atau CLI
<a name="kms_example_kms_PutKeyPolicy_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`PutKeyPolicy`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk mengubah kebijakan kunci untuk kunci KMS**  
`put-key-policy`Contoh berikut mengubah kebijakan kunci untuk kunci yang dikelola pelanggan.  
Untuk memulai, buat kebijakan kunci dan simpan dalam file JSON lokal. Dalam contoh ini, file tersebut adalah`key_policy.json`. Anda juga dapat menentukan kebijakan kunci sebagai nilai string `policy` parameter.  
Pernyataan pertama dalam kebijakan kunci ini memberikan izin AWS akun untuk menggunakan kebijakan IAM untuk mengontrol akses ke kunci KMS. Pernyataan kedua memberikan izin `test-user` pengguna untuk menjalankan `list-keys` perintah `describe-key` dan pada kunci KMS.  
Isi dari `key_policy.json`:  

```
{
    "Version":"2012-10-17",		 	 	 
    "Id" : "key-default-1",
    "Statement" : [
        {
            "Sid" : "Enable IAM User Permissions",
            "Effect" : "Allow",
            "Principal" : {
                "AWS" : "arn:aws:iam::111122223333:root"
            },
            "Action" : "kms:*",
            "Resource" : "*"
        },
        {
            "Sid" : "Allow Use of Key",
            "Effect" : "Allow",
            "Principal" : {
                "AWS" : "arn:aws:iam::111122223333:user/test-user"
            },
            "Action" : [
                "kms:DescribeKey",
                "kms:ListKeys"
            ],
            "Resource" : "*"
        }
    ]
}
```
Untuk mengidentifikasi kunci KMS, contoh ini menggunakan ID kunci, tetapi Anda juga dapat menggunakan kunci ARN. Untuk menentukan kebijakan kunci, perintah menggunakan `policy` parameter. Untuk menunjukkan bahwa kebijakan tersebut ada dalam file, kebijakan tersebut menggunakan `file://` awalan yang diperlukan. Awalan ini diperlukan untuk mengidentifikasi file pada semua sistem operasi yang didukung. Akhirnya, perintah menggunakan `policy-name` parameter dengan nilai`default`. Jika tidak ada nama kebijakan yang ditentukan, nilai defaultnya adalah`default`. Satu-satunya nilai yang valid adalah `default`.  

```
aws kms put-key-policy \
    --policy-name default \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --policy file://key_policy.json
```
Perintah ini tidak menghasilkan output apa pun. Untuk memverifikasi bahwa perintah itu efektif, gunakan `get-key-policy` perintah. Contoh perintah berikut mendapatkan kebijakan kunci untuk kunci KMS yang sama. `output`Parameter dengan nilai `text` mengembalikan format teks yang mudah dibaca.  

```
aws kms get-key-policy \
    --policy-name default \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --output text
```
Output:  

```
{
    "Version":"2012-10-17",		 	 	 
    "Id" : "key-default-1",
    "Statement" : [
        {
            "Sid" : "Enable IAM User Permissions",
            "Effect" : "Allow",
            "Principal" : {
                "AWS" : "arn:aws:iam::111122223333:root"
            },
            "Action" : "kms:*",
            "Resource" : "*"
            },
            {
            "Sid" : "Allow Use of Key",
            "Effect" : "Allow",
            "Principal" : {
                "AWS" : "arn:aws:iam::111122223333:user/test-user"
            },
            "Action" : [ "kms:Describe", "kms:List" ],
            "Resource" : "*"
        }
    ]
}

# Gunakan `ReEncrypt` dengan AWS SDK atau CLI
<a name="kms_example_kms_ReEncrypt_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`ReEncrypt`.

------
#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk mengenkripsi ulang pesan terenkripsi di bawah kunci KMS simetris yang berbeda (Linux dan macOS).**  
Contoh `re-encrypt` perintah berikut menunjukkan cara yang disarankan untuk mengenkripsi ulang data dengan CLI. AWS   
Berikan ciphertext dalam file.Dalam nilai `--ciphertext-blob` parameter, gunakan `fileb://` awalan, yang memberitahu CLI untuk membaca data dari file biner. Jika file tidak ada di direktori saat ini, ketik path lengkap ke file. Untuk informasi lebih lanjut tentang membaca nilai parameter AWS CLI dari file, lihat Memuat parameter [AWS CLI dari file di Panduan Pengguna Antarmuka Baris AWS Perintah dan Praktik Terbaik untuk Parameter File](https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-parameters-file.html) *Lokal di Blog Alat Baris AWS * [*Perintah*. Tentukan kunci KMS sumber, yang mendekripsi ciphertext. Parameter](https://aws.amazon.com/blogs/developer/best-practices-for-local-file-parameters/) tidak diperlukan saat mendekripsi dengan kunci KMS enkripsi `--source-key-id` simetris. AWS KMS bisa mendapatkan kunci KMS yang digunakan untuk mengenkripsi data dari metadata di gumpalan ciphertext. Tetapi selalu merupakan praktik terbaik untuk menentukan kunci KMS yang Anda gunakan. Praktik ini memastikan bahwa Anda menggunakan kunci KMS yang Anda inginkan, dan mencegah Anda mendekripsi ciphertext secara tidak sengaja menggunakan kunci KMS yang tidak Anda percayai. Tentukan kunci KMS tujuan, yang mengenkripsi ulang data.Parameter selalu diperlukan. `--destination-key-id` Contoh ini menggunakan ARN kunci, tetapi Anda dapat menggunakan pengidentifikasi kunci yang valid.Minta output teks biasa sebagai nilai teks.Parameter `--query` memberitahu CLI untuk mendapatkan hanya nilai bidang dari output. `Plaintext` `--output`Parameter mengembalikan output sebagai text.base64-decode plaintext dan menyimpannya dalam file.Contoh berikut pipa (\$1) nilai `Plaintext` parameter ke utilitas Base64, yang menerjemahkan itu. Kemudian, itu mengalihkan (>) output yang diterjemahkan ke file. `ExamplePlaintext`  
Sebelum menjalankan perintah ini, ganti kunci contoh IDs dengan pengidentifikasi kunci yang valid dari AWS akun Anda.  

```
aws kms re-encrypt \
    --ciphertext-blob fileb://ExampleEncryptedFile \
    --source-key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --destination-key-id 0987dcba-09fe-87dc-65ba-ab0987654321 \
    --query CiphertextBlob \
    --output text | base64 --decode > ExampleReEncryptedFile
```
Perintah ini tidak menghasilkan output. Output dari `re-encrypt` perintah adalah base64-decoded dan disimpan dalam file.  
Untuk informasi selengkapnya, lihat [ReEncrypt](https://docs.aws.amazon.com/kms/latest/APIReference/API_ReEncrypt.html)di *Referensi API Layanan Manajemen AWS Kunci*.  
**Contoh 2: Untuk mengenkripsi ulang pesan terenkripsi di bawah tombol KMS simetris yang berbeda (prompt perintah Windows).**  
Contoh `re-encrypt` perintah berikut adalah sama dengan yang sebelumnya kecuali bahwa ia menggunakan `certutil` utilitas untuk Base64-decode data plaintext. Prosedur ini membutuhkan dua perintah, seperti yang ditunjukkan pada contoh berikut.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda.  

```
aws kms re-encrypt ^
    --ciphertext-blob fileb://ExampleEncryptedFile ^
    --source-key-id 1234abcd-12ab-34cd-56ef-1234567890ab ^
    --destination-key-id 0987dcba-09fe-87dc-65ba-ab0987654321 ^
    --query CiphertextBlob ^
    --output text > ExampleReEncryptedFile.base64
```
Kemudian gunakan `certutil` utilitas  

```
certutil -decode ExamplePlaintextFile.base64 ExamplePlaintextFile
```
Output:  

```
Input Length = 18
Output Length = 12
CertUtil: -decode command completed successfully.

+  [Pelajari dasar-dasarnya](kms_example_kms_Scenario_Basics_section.md) 

------
#### [ CLI ]

**AWS CLI**  
**Untuk menjadwalkan penghapusan kunci KMS yang dikelola pelanggan.**  
`schedule-key-deletion`Contoh berikut menjadwalkan kunci KMS terkelola pelanggan yang ditentukan untuk dihapus dalam 15 hari.  
`--key-id`Parameter mengidentifikasi kunci KMS. Contoh ini menggunakan nilai ARN kunci, tetapi Anda dapat menggunakan ID kunci atau ARN dari kunci `--pending-window-in-days` KMS.Parameter menentukan panjang masa tunggu 7-30 hari. Secara default, masa tunggu adalah 30 hari. Contoh ini menentukan nilai 15, yang memberitahu AWS untuk secara permanen menghapus kunci KMS 15 hari setelah perintah selesai.  

```
aws kms schedule-key-deletion \
    --key-id arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab \
    --pending-window-in-days 15
```
Respons termasuk ARN kunci, status kunci, periode tunggu (`PendingWindowInDays`), dan tanggal penghapusan dalam waktu Unix. Untuk melihat tanggal penghapusan dalam waktu setempat, gunakan konsol AWS KMS. Kunci KMS dalam status `PendingDeletion` kunci tidak dapat digunakan dalam operasi kriptografi.  

```

# Gunakan `Sign` dengan AWS SDK atau CLI
<a name="kms_example_kms_Sign_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`Sign`.

Contoh tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Anda dapat melihat tindakan ini dalam konteks dalam contoh kode berikut: 
+  [Pelajari dasar-dasarnya](kms_example_kms_Scenario_Basics_section.md) 

------
#### [ CLI ]

**AWS CLI**  
**Contoh 1: Untuk menghasilkan tanda tangan digital untuk pesan**  
`sign`Contoh berikut menghasilkan tanda tangan kriptografi untuk pesan singkat. Output dari perintah mencakup `Signature` bidang yang dikodekan basis-64 yang dapat Anda verifikasi dengan menggunakan perintah. `verify`  
Anda harus menentukan pesan yang akan ditandatangani dan algoritma penandatanganan yang didukung oleh kunci KMS asimetris Anda. Untuk mendapatkan algoritma penandatanganan untuk kunci KMS Anda, gunakan perintah. `describe-key`  
Di AWS CLI v2, nilai `message` parameter harus dikodekan Base64. Atau, Anda dapat menyimpan pesan dalam file dan menggunakan `fileb://` awalan, yang memberitahu AWS CLI untuk membaca data biner dari file.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda. ID kunci harus mewakili kunci KMS asimetris dengan penggunaan kunci SIGN\$1VERIFY.  

```
msg=(echo 'Hello World' | base64)

aws kms sign \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --message fileb://UnsignedMessage \
    --message-type RAW \
    --signing-algorithm RSASSA_PKCS1_V1_5_SHA_256
```
Output:  

```
{
    "KeyId": "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",
    "Signature": "ABCDEFhpyVYyTxbafE74ccSvEJLJr3zuoV1Hfymz4qv+/fxmxNLA7SE1SiF8lHw80fKZZ3bJ...",
    "SigningAlgorithm": "RSASSA_PKCS1_V1_5_SHA_256"
}
```
Untuk informasi selengkapnya tentang penggunaan kunci KMS asimetris di AWS KMS, lihat [Kunci asimetris di AWS KMS di Panduan Pengembang](https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html) Layanan Manajemen *AWS Kunci*.  
**Contoh 2: Untuk menyimpan tanda tangan digital dalam file (Linux dan macOS)**  
`sign`Contoh berikut menghasilkan tanda tangan kriptografi untuk pesan singkat yang disimpan dalam file lokal. Perintah juga mendapatkan `Signature` properti dari respons, Base64-mendekodekannya dan menyimpannya dalam file. ExampleSignature Anda dapat menggunakan file tanda tangan dalam `verify` perintah yang memverifikasi tanda tangan.  
`sign`Perintah ini memerlukan pesan yang disandikan Base64 dan algoritma penandatanganan yang didukung oleh kunci KMS asimetris Anda. Untuk mendapatkan algoritma penandatanganan yang didukung oleh kunci KMS Anda, gunakan perintah. `describe-key`  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda. ID kunci harus mewakili kunci KMS asimetris dengan penggunaan kunci SIGN\$1VERIFY.  

```
echo 'hello world' | base64 > EncodedMessage

aws kms sign \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --message fileb://EncodedMessage \
    --message-type RAW \
    --signing-algorithm RSASSA_PKCS1_V1_5_SHA_256 \
    --output text \
    --query Signature | base64 --decode > ExampleSignature
```
Perintah ini tidak menghasilkan output. Contoh ini mengekstrak `Signature` properti output dan menyimpannya dalam file.

`tag-resource`Contoh berikut menambahkan `"Purpose":"Test"` dan `"Dept":"IT"` tag ke kunci KMS yang dikelola pelanggan. Anda dapat menggunakan tag seperti ini untuk memberi label kunci KMS dan membuat kategori kunci KMS untuk izin dan audit.  
Untuk menentukan kunci KMS, gunakan `key-id` parameter. Contoh ini menggunakan nilai ID kunci, tetapi Anda dapat menggunakan ID kunci atau kunci ARN dalam perintah ini.  

```
aws kms tag-resource \

# Gunakan `UpdateAlias` dengan AWS SDK atau CLI
<a name="kms_example_kms_UpdateAlias_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`UpdateAlias`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk mengaitkan alias dengan kunci KMS yang berbeda**  
`update-alias`Contoh berikut mengaitkan alias `alias/test-key` dengan kunci KMS yang berbeda.  
`--alias-name`Parameter menentukan alias. Nilai nama alias harus dimulai dengan`alias/`. `--target-key-id` Parameter menentukan kunci KMS untuk mengaitkan dengan alias. Anda tidak perlu menentukan kunci KMS saat ini untuk alias.  

```
aws kms update-alias \
    --alias-name alias/test-key \
    --target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Perintah ini tidak menghasilkan output. Untuk menemukan alias, gunakan `list-aliases` perintah.

# Gunakan `Verify` dengan AWS SDK atau CLI
<a name="kms_example_kms_Verify_section"></a>

Contoh kode berikut menunjukkan cara menggunakan`Verify`.

------
#### [ CLI ]

**AWS CLI**  
**Untuk memverifikasi tanda tangan digital**  
`verify`Perintah berikut memverifikasi tanda tangan kriptografi untuk pesan singkat yang disandikan Base64. ID kunci, pesan, jenis pesan, dan algoritma penandatanganan harus sama dengan yang digunakan untuk menandatangani pesan.  
Di AWS CLI v2, nilai `message` parameter harus dikodekan Base64. Atau, Anda dapat menyimpan pesan dalam file dan menggunakan `fileb://` awalan, yang memberitahu AWS CLI untuk membaca data biner dari file.  
Tanda tangan yang Anda tentukan tidak dapat dikodekan base64. Untuk bantuan mendekode tanda tangan yang dikembalikan `sign` perintah, lihat contoh `sign` perintah.  
Output dari perintah termasuk `SignatureValid` bidang Boolean yang menunjukkan bahwa tanda tangan telah diverifikasi. Jika validasi tanda tangan gagal, `verify` perintah juga gagal.  
Sebelum menjalankan perintah ini, ganti ID kunci contoh dengan ID kunci yang valid dari AWS akun Anda.  

```
aws kms verify \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
    --message fileb://EncodedMessage \
    --message-type RAW \
    --signing-algorithm RSASSA_PKCS1_V1_5_SHA_256 \
    --signature fileb://ExampleSignature
```
Output:  

```
{
    "KeyId": "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",
