Readable string for coupon codes or auth tokens, something people can read/write and do not confuse.

• more information density than hex -> shorter codes
• less confusion than base64 -> readable codes

Install

• As Rails plugin: script/plugin install git://github.com/grosser/readable_random.git
• As gem: sudo gem install grosser-readable_random --source http://gems.github.com

Usage

ReadableRandom.get(5) -> 'aB23r'

# user.rb
def generate_token
  while token.blank? or User.find_by_token(token)
    self.token = ReadableRandom.get(6)
  end
end

TODO

• prevent nasty words by not using vovels or a more clever tick...
