Request Syntax Request Parameters Response Elements Errors Examples See Also

DeleteAlias

Deletes the specified alias.

Note

Adding, deleting, or updating an alias can allow or deny permission to the KMS key. For details, see Using ABAC in AWS KMS in the AWS Key Management Service Developer Guide.

Because an alias is not a property of a KMS key, you can delete and change the aliases of a KMS key without affecting the KMS key. Also, aliases do not appear in the response from the DescribeKey operation. To get the aliases of all KMS keys, use the ListAliases operation.

Each KMS key can have multiple aliases. To change the alias of a KMS key, use DeleteAlias to delete the current alias and CreateAlias to create a new alias. To associate an existing alias with a different KMS key, call UpdateAlias .

Cross-account use: No. You cannot perform this operation on an alias in a different AWS account.

Required permissions

kms:DeleteAlias on the alias (IAM policy).
kms:DeleteAlias on the KMS key (key policy).

For details, see Controlling access to aliases in the AWS Key Management Service Developer Guide.
