This a GnuPG wrapper built with Ruby.
The gem api is modeled after jruby-pgp for compatibility reasons with a legacy application.
This gem is validated with multiple versions of gpg and multiple operating systems.

Add this line to your application's Gemfile:

gem 'ruby-pgp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby-pgp

The feature set is very bare, and restricted to the following operations:

• Encrypt a file to a known list of Public Key(s).

• Decrypt a file using a given set of Private Key(s).

• Public and Private keys may be read in from disk or from memory.

• Verify the signature of a file that you are decrypting. (thanks, @superchris)

• Use password-protected Private Keys. (thanks, @superchris)

• Sign a file from the file system. (thanks, @superchris)

Currently, you cannot do the following (These are TODO items):

• Verify any signatures of public / private keys.

• Create new Private Keys / generate public keys from a given Private Key.

• Sign a file that you are encrypting.

• Obtain the name of the file that was encrypted. (Should be an easy feature to add.)

• Obtain the "modificationTime" (timestamp) of the encrypted data / file.

• Verify a public key based on information from a key server.

This gem currently features everything I need and nothing I don't. Pull requests are very much welcome; feature requests will be considered.

For usage examples, see the below test files:

Encryption: spec/lib/pgp/encryptor_spec.rb
Decryption: spec/lib/pgp/decryptor_spec.rb

The .travis.yml file describes our testing strategy for multiple OS.
We run the test suite against multiple OS versions with Ruby installed.
