A couple examples of using asymmetric RSA signing and encryption using Ruby's OpenSSL libraries.
require 'openssl'
key = OpenSSL::PKey::RSA.new(2048)
p encrypted_string = key.public_encrypt('my plaintext string', OpenSSL::PKey::RSA::PKCS1_OAEP_PADDING)
p decrypted_string = key.private_decrypt(encrypted_string, OpenSSL::PKey::RSA::PKCS1_OAEP_PADDING)
