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.
