A few years ago I implemented a hash algorithm for XPath/XSLT using XPath 2.0 features (i.e. it uses the string-to-codepoints() function). It also uses some large (prime) numbers, such as 2^50, so you would need to run it on a 64-bit machine.

Hello!

Given an XSLT 3/XPath 3.1 processor (Saxon-J 12.9 in oXygen), is there a
practical way to hash strings?

I'd suppose there might be a Java function, but if so, I have no idea
what it is, and some searching sugguests hashing isn't a core function
thing.

Thanks!
