OpenSSL provides SSL, TLS and general purpose cryptography. It wraps the OpenSSL library.

The openssl gem is available at rubygems.org. You can install with:

gem install openssl 

You may need to specify the path where OpenSSL is installed.

gem install openssl -- --with-openssl-dir=/opt/openssl 

Alternatively, you can install the gem with bundler:

# Gemfile gem 'openssl' # or specify git master gem 'openssl', git: 'https://github.com/ruby/openssl'

After doing bundle install, you should have the gem installed in your bundle.

Once installed, you can require "openssl" in your application.

require "openssl"

NOTE: If you are using Ruby 2.3 (and not Bundler), you must activate the gem version of openssl, otherwise the default gem packaged with the Ruby installation will be used:

gem "openssl" require "openssl"

See https://ruby.github.io/openssl/.
