Create an alias - Key Management Service (2024)

Background information

• An alias must contain the alias/ prefix. An alias name excluding the prefix must be 1 to 255 characters in length and can contain letters, digits, underscores (_), hyphens (-), and forward slashes (/).
• If you want to allow a Resource Access Management (RAM) user to create an alias, you must create a custom policy to grant the RAM user the required permissions.

  The following sample policy allows User 123456 to create an alias named alias/example for CMK 08ec3bb9-034f-485b-b1cd-3459baa8****:

  { "Version": "1", "Statement": [ { "Effect": "Allow", "Action": [ "kms:CreateAlias" ], "Resource": [ "acs:kms:cn-hangzhou:123456:key/08ec3bb9-034f-485b-b1cd-3459baa8****", "acs:kms:cn-hangzhou:123456:alias/example" ] } ]}

• A new alias created for a CMK does not affect the existing aliases of the CMK.
