RSA/MD5 library?


I'm new to Ruby, and I wanted to implement a new project using this wonderful language, but I need an RSA library.

I need to create a hash for a string, then sign it with a private key, then get the base64 string. Do you know of any library available for this?

I found but I need PKCS10...

Any help is appreciated! (I'd hate having to do this on another language...)
