generateGUID

public static java.lang.String generateGUID()

Generates a unique ID based on the Yarrow secure random number generator. Yarrow preserves its seed in $java.io.tmpdir/seedfile, so the chances of getting a collision are amazingly, amazingly small. Even on separate machines, this shouldn't yield matches.
