Simple gem to provide MD5 and SHA1 digest functionality. It uses ObjC library, included in vendor directory


Add this line to your application's Gemfile:

gem 'rm-digest'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rm-digest


digestSHA1String = RmDigest::SHA1.hexdigest('some string')
digestMD51String = RmDigest::MD5.hexdigest('some string')

Gem provides byte based digests

digestSHA1Bytes = RmDigest::SHA1.digest('some string')
digestMD51Bytes = RmDigest::MD5.digest('some string')
