title: What are the options for generating user friendly alpha numeric IDs (like business id, SKU)
body: <p>Here are the requirements:</p>
  
  <p>Must be alphanumeric, 8-10 characters so that it is user friendly. These will be stored as unique keys in database. I am using Guids as primary keys so an option to use GUids to generate these unique Ids would be preferable.</p>
  
  <p>I am thinking on the lines of a base-n converter that takes a Guid and converts to an 8 character unique string.</p>
  
  <p>Short, light-weight algorithm preferred as it would be called quite often.</p>
