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.
