Example 1: To list all aliases in an Amazon account and Region

The following example uses the list-aliases command to list all aliases in the default Region of the Amazon account. The output includes aliases associated with Amazon managed KMS keys and customer managed KMS keys.

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"
        },
        ...
    ]
}

Example 2: To list all aliases for a particular KMS key

The following example uses the list-aliases command and its key-id parameter to list all aliases that are associated with a particular KMS key.

Each alias is associated with only one KMS key, but a KMS key can have multiple aliases. This command is very useful because the Amazon KMS console lists only one alias for each KMS key. To find all aliases for a KMS key, you must use the list-aliases command.

This example uses the key ID of the KMS key for the --key-id parameter, but you can use a key ID, key ARN, alias name, or alias ARN in this command.

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",
            "AliasName": "alias/project121-test"
        }
    ]
}
