# Dekripsi
Contoh-contoh ini menunjukkan entri AWS CloudTrail log untuk operasi [Dekripsi](https://docs.aws.amazon.com/kms/latest/APIReference/API_Decrypt.html).
Entri CloudTrail log untuk `Decrypt` operasi selalu menyertakan `encryptionAlgorithm` dalam `requestParameters` bahkan jika algoritma enkripsi tidak ditentukan dalam permintaan. Ciphertext dalam permintaan dan plaintext dalam respons dihilangkan.

## Dekripsi kegagalan dengan kunci enkripsi simetris standar
Contoh entri CloudTrail log berikut mencatat `Decrypt` operasi yang gagal dengan kunci KMS enkripsi simetris standar. Exception (`errorCode`) dan error message (`errorMessage`) disertakan membantu Anda mengatasi kesalahan.
Dalam hal ini, kunci KMS enkripsi simetris yang ditentukan dalam `Decrypt` permintaan bukanlah kunci KMS enkripsi simetris yang digunakan untuk mengenkripsi data.

## Dekripsi kegagalan dengan kunci KMS di toko kunci eksternal
Contoh entri CloudTrail log berikut mencatat permintaan gagal untuk `Decrypt` operasi dengan kunci KMS di [penyimpanan kunci eksternal](keystore-external.md). CloudWatch mencatat permintaan yang gagal, selain permintaan yang berhasil. Saat merekam kegagalan, entri CloudTrail log menyertakan pengecualian (ErrorCode) dan pesan kesalahan yang menyertainya (ErrorMessage).
Jika permintaan gagal mencapai proxy penyimpanan kunci eksternal Anda, seperti dalam contoh ini, Anda dapat menggunakan `requestId` nilai untuk mengaitkan permintaan yang gagal dengan permintaan yang sesuai, log proxy penyimpanan kunci eksternal Anda, jika proxy Anda menyediakannya.
Untuk bantuan terkait `Decrypt` permintaan di toko kunci eksternal, lihat[Kesalahan dekripsi](xks-troubleshooting.md#fix-xks-decrypt).

## Dekripsi dengan kunci enkripsi simetris standar melalui koneksi TLS pasca-kuantum
Berikut ini adalah contoh entri CloudTrail log untuk `Decrypt` operasi dengan kunci enkripsi simetris standar melalui koneksi TLS pasca-kuantum. Bidang KeyExchange di `tlsDetails` bagian menyebutkan`X25519MLKEM768`. [Ini adalah algoritma *hibrida* yang menggabungkan [Elliptic Curve Diffie-Hellman (ECDH) melalui Curve](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%E2%80%93Hellman)[25519](https://en.wikipedia.org/wiki/Curve25519), algoritma pertukaran kunci klasik yang digunakan saat ini di TLS, dengan [Module-Lattice-Based Key-Encapsulation Mechanism (), enkripsi](https://csrc.nist.gov/pubs/fips/203/final) kunci publik dan algoritma pembentukan kunci yang telah ditetapkan oleh National Institute for Standards and Technology (NISTML-KEM) sebagai algoritma kesepakatan kunci pasca-kuantum standar pertamanya.](https://csrc.nist.gov/pubs/fips/203/final)
