Returns information about the signing certificates associated with the specified user. If there are none, the action returns an empty list.
Although each user is limited to a small number of signing certificates, you can still paginate the results using the MaxItems
and Marker
parameters.
If the UserName
field is not specified, the user name is determined implicitly based on the AWS access key ID used to sign the request. Because this action works for access keys under the AWS account, this API can be used to manage root credentials even if the AWS account has no associated users.
