title: Turning an integer into random string and back again
body: <p>what I'm wanting is to convert an integer into a string. For example, 123456789 may become 8GFsah93r ... you know like Youtube, Pastebin and what not. I then want to convert it back.</p>
  
  <p>I'm working with large integers, for example: 131569877435989900</p>
  
  <p>Take a look at this link: <a href="http://codepad.viper-7.com/wHKOMi" rel="noreferrer">http://codepad.viper-7.com/wHKOMi</a></p>
  
  <p>This is my attempt using a function I found on the web, obviously... it's not correctly converting back to integer. I'm needing something that does this realiably.</p>
  
  <p>Thanks</p>
