Thanks. I looked at it, but could not understand it. I will use md5
because I also use it in my PHP-applications, and I can therefore use

Is the same thing:

require ‘digest’


You need to know how to read an API, you must use it every day … The
“always open” are:

http://www.ruby-doc.org/core/ and http://api.rubyonrails.org/

Expend a while figuring it out.
