There is already fn:hash in the "XPath /XQuery 4.0 Functions and Operators"
-
https://qt4cg.org/specifications/xpath-functions-40/Overview.html#func-hash

It accepts input as xs:hexBinary or xs:base64Binary, besides, of course,
xs:string.

At present 5 hashing algorithms are supported: MD5, SHA-1, SHA-256, Blake3,
CRC-32

The resulting hash value is returned also as xs:hexBinary.

That may be helpful, especially if you have access to an existing
implementation - such as BaseX or Saxon.
