It's actually pretty easy:
	require 'digest/md5'
	Digest::MD5.new 'a random string.' # => 8a6194e053d7a326fe301e902043bec1
This gets you a new Digest::MD5 object, which you'll usually .to_s.  If all you
want is a string, you can do
	Digest::MD5.hexdigest "Even randomer:  #{rand}"
	# => "c69a37bb0328b781901665c671e1b367"
which just returns a string.

http://ruby-doc.org/stdlib/libdoc/digest/rdoc/index.html has more information.
