#### [ CLI ]
**AWS CLI**
**Como criar um alias para uma chave do KMS**
O comando `create-alias` a seguir cria um alias com o nome `example-alias` para a chave do KMS identificada pelo ID de chave `1234abcd-12ab-34cd-56ef-1234567890ab`.
Os nomes de alias devem começar com `alias/`. Não use nomes de alias que comecem com`alias/aws`; eles são reservados para uso por AWS.
```
aws kms create-alias \
--alias-name alias/example-alias \
--target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Esse comando não retorna resultados. Use o `list-aliases` comando para visualizar o novo alias.

#### [ CLI ]
**AWS CLI**
**Como criar uma concessão**
O exemplo de `create-grant` a seguir cria uma concessão que permite que o usuário `exampleUser` use o comando `decrypt` na chave do KMS `1234abcd-12ab-34cd-56ef-1234567890ab` de exemplo. A entidade principal descontinuada é o perfil `adminRole`. A concessão usa a restrição de concessão `EncryptionContextSubset` para conceder essa permissão apenas quando o contexto de criptografia na solicitação `decrypt` incluir o par de chave/valor `"Department": "IT"`.
```
aws kms create-grant \
--key-id 1234abcd-12ab-34cd-56ef-1234567890ab \
--grantee-principal arn:aws:iam::123456789012:user/exampleUser \

#### [ CLI ]
**AWS CLI**
**Exemplo 1: Para criar uma chave KMS gerenciada pelo cliente no AWS KMS**
O exemplo de `create-key` a seguir cria uma chave do KMS de criptografia simétrica.
Não é necessário especificar parâmetros para criar a chave básica do KMS (uma chave de criptografia simétrica). Os valores padrão desses parâmetros criam uma chave de criptografia simétrica.
Como esse comando não especifica uma política de chave, a chave do KMS adota a [política de chave padrão](https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html#key-policy-default) para chaves do KMS criadas programaticamente. Use o comando `get-key-policy` para visualizar a política de chave. Use o comando `put-key-policy` para alterar a política de chave.
```
aws kms create-key
```
O comando `create-key` retorna os metadados da chave, incluindo o ID da chave e o ARN da nova chave do KMS. Você pode usar esses valores para identificar a chave KMS em outras operações do AWS KMS. A saída não inclui as tags. Use `list-resource-tags command` para visualizar as tags de uma chave do KMS.

**Exemplo 5: criar uma chave HMAC do KMS**
O exemplo de `create-key` a seguir cria uma chave do KMS com HMAC de 384 bits. O valor `GENERATE_VERIFY_MAC` é obrigatório para o parâmetro `--key-usage`, mesmo que seja o único valor válido para chaves do KMS com HMAC.

**Exemplo 8: criar uma chave do KMS em um repositório de chaves externo**
O exemplo de `create-key` a seguir cria uma chave do KMS no repositório de chaves externo especificado. Os parâmetros `--custom-key-store-id`, `--origin` e `--xks-key-id` são obrigatórios neste comando.
O parâmetro `--xks-key-id` especifica o ID de uma chave de criptografia simétrica existente no gerenciador de chaves externo. Essa chave serve como o material de chave externo para a chave do KMS. O valor do parâmetro `--origin` deve ser `EXTERNAL_KEY_STORE`. O parâmetro `custom-key-store-id` deve identificar um repositório de chaves externo conectado ao proxy do repositório de chaves externo.
```
aws kms create-key \
--origin EXTERNAL_KEY_STORE \
--custom-key-store-id cks-9876543210fedcba9 \
--xks-key-id bb8562717f809024

O `describe-key` exemplo a seguir obtém informações detalhadas sobre a chave AWS gerenciada para o Amazon S3 na conta e região do exemplo. Você pode usar esse comando para encontrar detalhes sobre chaves AWS gerenciadas e chaves gerenciadas pelo cliente.
Use o parâmetro `key-id` para especificar a chave do KMS. Este exemplo usa um valor de nome de alias, mas você pode usar um ID de chave, o ARN da chave, o nome do alias ou o ARN do alias neste comando.
```
aws kms describe-key \

#### [ CLI ]
**AWS CLI**
**Para habilitar uma chave do KMS**
O exemplo de `enable-key` a seguir habilita uma chave gerenciada pelo cliente. Você pode usar um comando como esse para habilitar uma chave do KMS que foi temporariamente desabilitada usando o comando `disable-key`. Você também pode usá-lo para habilitar uma chave do KMS que está desabilitada porque foi programada para exclusão, mas a exclusão foi cancelada.
Use o parâmetro `key-id` para especificar a chave do KMS. Este exemplo usa um valor de ID de chave, mas você pode usar um ID de chave ou o valor do ARN da chave neste comando.
Antes de executar esse comando, substitua o ID da chave de exemplo por um ID válido.
```
aws kms enable-key \
--key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Este comando não produz saída. Use o `describe-key` comando para verificar se a chave KMS está habilitada. Consulte os valores dos campos `KeyState` e `Enabled` na saída `describe-key`.

#### [ CLI ]
**AWS CLI**
**Exemplo 1: Para listar todos os aliases em uma AWS conta e região**
O exemplo a seguir usa o `list-aliases` comando para listar todos os aliases na região padrão da AWS conta. O resultado inclui aliases associados às chaves KMS AWS gerenciadas e às chaves KMS gerenciadas pelo cliente.
```
aws kms list-aliases
```
Saída:
```
{
"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"
},
...
]
}
```
**Exemplo 2: como listar todos os aliases de uma chave específica do KMS**
O exemplo a seguir usa o comando `list-aliases` e seu parâmetro `key-id` para listar todos os aliases associados a uma determinada chave do KMS.
Cada alias é associado a apenas um chave do KMS, mas uma chave do KMS pode ter vários aliases. Esse comando é muito útil porque o console AWS KMS lista somente um alias para cada chave KMS. Você deve usar o comando `list-aliases` para localizar todos os aliases de uma chave do KMS.
Este exemplo usa o ID de chave da chave do KMS no parâmetro `--key-id`, mas você pode usar um ID de chave, o ARN da chave, o nome do alias ou o ARN do alias neste comando.
```
aws kms list-aliases --key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
Saída:
```
{
"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",
"AliasName": "alias/project121-test"
}
]
}

#### [ CLI ]
**AWS CLI**
**Para visualizar as concessões em uma chave AWS KMS**
O `list-grants` exemplo a seguir exibe todas as concessões na chave KMS AWS gerenciada especificada para o Amazon DynamoDB em sua conta. Essa concessão permite que o DynamoDB use a chave do KMS em seu nome para criptografar uma tabela do DynamoDB antes de gravá-la no disco. Você pode usar um comando como esse para visualizar as concessões nas chaves KMS AWS gerenciadas e nas chaves KMS gerenciadas pelo cliente na AWS conta e na região.
Este comando usa o parâmetro `key-id` com um ID de chave para identificar a chave do KMS. Você pode usar um ID de chave ou o ARN da chave para identificar a chave do KMS. Para obter o ID da chave ou o ARN da chave de uma chave KMS AWS gerenciada, use o `list-keys` comando ou. `list-aliases`
```
aws kms list-grants \
--key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
O resultado mostra que a concessão fornece ao Amazon DynamoDB permissão para usar a chave do KMS para operações criptográficas e permite que ele visualize detalhes sobre a chave do KMS (`DescribeKey`) e descontinue concessões (`RetireGrant`). A restrição `EncryptionContextSubset` limita a permissão às solicitações que incluem os pares de contexto de criptografia especificados. Como resultado, as permissões na concessão são efetivas somente na conta especificada e na tabela do DynamoDB.
