Deletes the specified alias.
Adding, deleting, or updating an alias can allow or deny permission to the KMS key.
For details, see ABAC
for KMS in the 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 Amazon Web Services 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 Key Management Service Developer Guide.

| KMSInvalidStateException | The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide. For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception. |
