hello all,

does anyone have the experience about public key encryption with ruby? I  
know how to use the module OpenSSL::PKey::RSA to create public/private  
key pair and encrypt/decrypt with the key pair. however, if I only know  
other guy’s public key, is there any module or method to encrypt data  
with the guy’s public key?

thanks a lot.
