I need help with digital signatures in ruby. What I'm aiming to do is have the application on a users computer receive a file digitally signed from me. The user application must then, without using any gems, verify the file is valid and read it. Could anyone help me?

Depending on the country of the receiver user there might be more optimized applications available.
