This gem introduces OpenSSL::PKey::SSH class with the ability to parse OpenSSH format public keys and return a correct OpenSSL::PKey type object. This is a convenience class used to parse the specific format of the OpenSSH public key.

Private OpenSSH key strings are forwarderd without modification to OpenSSL::PKey::RSA.new and OpenSSL::Pkey::DSA.new respectively.

Add this line to your application's Gemfile:

gem 'openssl-ssh'

And then execute:

$ bundle

Or install it yourself as:

$ gem install openssl-ssh

require 'openssl/ssh'

OpenSSL::PKey::SSH.new File.read('/path/to/openssh/public.key')
# <OpenSSL::PKey::RSA:0x00007fb93f9f8788>

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
