The functionality of this Gem has been merged into ruby/openssl
For further information, please visit ruby/openssl#635.

The concept of provider was introduced with OpenSSL 3. https://www.openssl.org/docs/man3.0/man7/migration_guide.html

With OpenSSL 3, it is possible to specify the provider to be used by any application, either programmatically or through a configuration file. However, ruby/openssl 3.1.0 does not have an API to load providers without configuration file. This Gem provides OpenSSL::Provider class with APIs to load providers.

Install the gem and add to the application's Gemfile by executing:

$ bundle add openssl_provider

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install openssl_provider

require 'openssl_provider'

legacy = OpenSSL::Provider.load("legacy")

OpenSSL::Provider.providers
# => [#<OpenSSL::Provider name="default">, #<OpenSSL::Provider name="legacy">]

# default provider does not support RC4
# OpenSSL::Cipher.new("RC4")
# => OpenSSL::Cipher::CipherError: unsupported
cipher = OpenSSL::Cipher.new("RC4")

# do something with cipher...

OpenSSL::Provider.unload(legacy)
