Hello Nikhil, Looking at how my proposed solution ( https://review.openstack.org/319659) was inefficient. Instead of using a dummy string to identify encrypted data, I have been thinking about handling the exceptions that are generated when you try to decrypt unencrypted data, since it would either cause a "TypeError" or "ValueError" as seen here https://github.com/openstack/glance/blob/24fae90c179d306c3f6763e9b4412a3e7ebd67e9/glance/db/sqlalchemy/migrate_repo/versions/017_quote_encrypted_swift_credentials.py#L125 . But I am still waiting a review and proposed solution. Thanks Konrad -------------- next part -------------- An HTML attachment was scrubbed...
