Working With Rails

Gnupg

A Command-line wrapper for GnuPG in ruby/rails. The secret decryption key only occupies the working directory for the duration of the decryption.

Requirements:
   GnuPG installed on your box
   A working directory with the public key installed
   An ascii-export of your secret key, for dynamic loading/unloading of the decryption key

Usage:
   For Rails, you'll definitely want to set the absolute paths,
   using RAILS_ROOT/path/to/your/working/directory

Assuming these options..
workdir = /tmp/gnupg_test/
passphrase = uglydonkeys

gnupg = GnuPG.new     :binary=>"/opt/local/bin/gpg",
                    :workdir=>"/tmp/gnupg_test",
                    :homedir_pub=>"/tmp/gnupg_test",
                    :homedir_sec=>"/tmp/gnupg_test",
                    :recipient=>"your uid"

puts plain_message = "no more saddam, haha" 
puts encrypted_message = gnupg.encrypt(plain_message)

1. Load ascii decryption sec key, wherever you may have it gnupg.load_key File.read(“secret_key.asc”) puts gnupg.decrypt(encrypted_message,’uglydonkeys’) gnupg.drop_key

Thats it! You can, of course, store whatever you want to files, or to the database.
