Retiring a Grant

Function

This API is used to retire grants. After grants are retired, the granted users do not have the permission to operate keys.

For example, user A grants user B the permission to operate key A and grants user C the permission to revoke the grant. In this case, all users can retire the grant. After the grant is retired, user B cannot use key A.

Only the following users can retire a grant:

User who created the grant

User who has been granted the retiring_principal permission

User who has been granted the grantee_principal permission if retire-grant is contained in the grant list
