Re: XML-proof UIDs
This is what GUIDs/UUIDs were designed for, and they're used broadly. They're standardized in ISO 11578 [1], although there's a very similar public description in an expired Internet Draft [2]. Microsoft also publishes a description of how they generate their GUIDs, but I can't find it right now. That draft has been replaced by the UUID/URN draft that I mentioned. It includes all of the original text. Actually, I rewrote most of it so it reads better now. It's actually in the final comment period and should show up as an official RFC in few weeks. /r$ -- Rich Salz Chief Security Architect DataPower Technology http://www.datapower.com XS40 XML Security Gateway http://www.datapower.com/products/xs40.html XML Security Overview http://www.datapower.com/xmldev/xmlsecurity.html - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
XML-proof UIDs
Does anyone have robust code to generate globally unique IDs which won't break XML parsing, and work on several platforms? I was thinking of using an entropy pool to seed a cryptographic PRNG, used to generate a sequence of SHA-1 hashes, dumped to an XML-armored representation.
