Randomly generate string

Hello Guys,
        If you want to generate random string with specific some constraint like at least single upper case, lower case and digit. or many more.


Here i have found gem called 'passgen'. which provides many possible changes.
gem install passgen


On console:
require 'rubygems'
require 'passgen'
Passgen::generate(:lowercase => true, :uppercase => true, :digits => true, :length => 10)
