How do you encrypt a databag item using Ridley?

[trekr5]

What would be the Ridley equivalent of knife data bag create passwords mysql --secret-file /tmp/my_data_bag_key ( where passwords is the name of the databag, mysql is the databag item and “/tmp/my_data_bag_key” is the path to the location in which the file that contains the secret-key is located)?

I've found no existing method of doing so. This seems like a pretty simple use case for ridley: creating an encrypted data bag. Anyone have a suggestion...beer payments provided; or physical beer..if in SF or Seattle.
