Is a GUID (String Package)

Apologies for reviving an old thread, but would anyone be able to save this GUID toolkit for LV2009?

 

For what it's worth, attached is a zip containing three Create GUID implementations consistent with IETF RFC-4122:

attachicon.gifGUID LV11.zip

Version 1: Timestamp
Version 3: MD5
Version 4: Random

The V3 implementation requires the OpenG MD5 library. Also included is a VI that generates a 100 ns base timestamp (used in the V1 implementation, actually works as advertised now), along with a typedef that is used in the implementations.

There is no V5 VI, I haven't tracked down the SHA-1 library you have been talking about, but it should be trivial to modify the existing V3 VI (replace the checksum call with a SHA-1 and modify the version bitmask) if it doesn't already have the functionality you describe.

If there's interest in having the Is A GUID method perform a basic timestamp validation for V1 GUIDs, I can throw some code together.
