title: HowTo generate Random Token in Ruby
body: <p>I want generate unique ID for my rails-application. To send them to the user.
  <a href="http://ruby-doc.org/stdlib-1.9.3/libdoc/securerandom/rdoc/SecureRandom.html" rel="nofollow">SecureRandom</a>-support ended for 1.9.3.
  The UUIDTool is good for the Admin-Tooken, but not for a short url-Restful ID like www.site.com/h6scre55x66</p>
  
  <p>Is there an alternative for rails to SecureRandom?</p>
  
  <p>Thanks</p>
