pki

Amazingly simple pki encryption, using undocumented OpenSSL functions. Use public keys to encrypt data, and private keys to decrypt them.

  # uses a randomly generated RSA private key
  pki = Pki.new
  encrypted = pki.encrypt('monkey')
  pki.decrypt(encrypted) == 'monkey'

  # load a private key from a stream.
  # if no public key is specified, a new one is created using the existing
  # private key.
  pki = Pki.new(:private_key => File.open('my_priv_key'))

  # load private/public keys
  pki = Pki.new :private_key => "-----BEGIN RSA PRIVATE KEY-----\n..."
  pki.public_key = OpenSSL::PKey::RSA.new(...)

  # you can pretty much load private keys from strings, from streams, or PKey
  objects that respond to #public_encrypt and #private_decrypt.
