OpenSSL for Ruby provides access to SSL/TLS and general-purpose cryptography based on the OpenSSL library.
OpenSSL for Ruby is sometimes referred to as openssl in all lowercase or Ruby/OpenSSL for disambiguation.
OpenSSL for Ruby is released as a RubyGems gem. At the same time, it is part of the standard library of Ruby. This is called a default gem.
Each stable branch of OpenSSL for Ruby will remain supported as long as it is included as a default gem in supported Ruby branches.

Note The openssl gem is included with Ruby by default, but you may wish to upgrade it to a newer version available at rubygems.org.
To upgrade it, you can use RubyGems:
gem install openssl
In some cases, it may be necessary to specify the path to the installation directory of the OpenSSL library.
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 running bundle install, you should have the gem installed in your bundle.
Once installed, you can require "openssl" in your application.
require "openssl"See https://ruby.github.io/openssl/.
