This gem provides timing-safe string compare with double HMAC pattern. It is inspired by suryagh's tsscmp library.

Add this line to your application's Gemfile:

gem'tsscmp-ruby'

And then execute:

$ bundle 

Or install it yourself as:

$ gem install tsscmp-ruby 

require'tsscmp-ruby'Tsscmp.compare("a","a")#=> trueTsscmp.compare("a","b")#=> false
