Does anyone have a component / method that will take a GUID and convert 
it to a BASE64 or ASCII85 string?

I need to have a uniquely generated string for a gift card module I am 
writing and I need it to be <= 22 characters.

Best Regards,

Shane

If you go to http://www.deja.com and search through the newsgroup archives, 
examples of base64 algorithms have been posted many times before.  I have 
never heard of Ascii85 before, but a search on any web search engine 
produces links to many source code examples.

A base64-encoded GUID would not satisfy that requirement as it would always 
be 24 characters in length, as would a full ASCII85-encoded GUID as well. 
In the case of ASCII85, though, you could truncate off the begin and end 
markers (if you remember to put them back on before decoding), resulting in 
20 characters.
