This time you didn't mention a requirement of exactly 20 characters. If 
that's not strictly required, it's worth pointing out that the hyphen 
character '-' is also URL safe.

So in that case you could just use the standard 36-character 
representation of a UUID, with its four hyphens. It would save you the 
trouble of regex matching and substitution, as Guillaume spelled out.


Best,
Geoff
