OpenPGP.rb

This is a pure-Ruby implementation of the OpenPGP Message Format (RFC 4880).

About OpenPGP

OpenPGP is the most widely-used e-mail encryption standard in the world. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force (IETF) Proposed Standard RFC 4880. The OpenPGP standard was originally derived from PGP (Pretty Good Privacy), first created by Phil Zimmermann in 1991.

Features

  • Encodes and decodes ASCII-armored OpenPGP messages.

  • Parses OpenPGP messages into their constituent packets.

    • Supports both old-format (PGP 2.6.x) and new-format (RFC 4880) packets.

  • Includes a GnuPG wrapper for features that are not natively supported.

Examples

require 'openpgp'

Decoding an ASCII-armored message

require 'open-uri'
text = open('http://ar.to/pgp.txt').read

msg = OpenPGP::Message.parse(OpenPGP.dearmor(text))

Generating a new keypair

gpg = OpenPGP::Engine::GnuPG.new(:homedir => '~/.gnupg')
key_id = gpg.gen_key({
  :key_type      => 'DSA',
  :key_length    => 1024,
  :subkey_type   => 'ELG-E',
  :subkey_length => 1024,
  :name          => 'J. Random Hacker',
  :comment       => nil,
  :email         => '[email protected]',
  :passphrase    => 'secret passphrase',
})
