Converts strings to/from a slightly modified base64 that contains only url-safe characters


Add this line to your application's Gemfile:

gem 'url_safe_base64'

And then execute:

$ bundle

Or install it yourself as:

$ gem install url_safe_base64


Normal Base64:

Base64.encode64 "Test string"                    #=> "VGVzdCBzdHJpbmc=\n"
Base64.decode64 "VGVzdCBzdHJpbmc=\n"             #=> "Test string"

With this gem:

UrlSafeBase64.encode64 "Test string"             #=> "VGVzdCBzdHJpbmc"
UrlSafeBase64.decode64 "VGVzdCBzdHJpbmc=\n"      #=> "Test string"
