(Unfortunately lots of other password hash formats are all over the map with various combinations fixed length Base64 strings, prefixes, and field separators, so a general passwordHash validator would probably be watered down to accept almost anything.)
Any interest in a PR for a bcrypt password hash validation? It would be a simple regex matcher of
/^\$2[aby]?\$[\d]+\$[./A-Za-z0-9]{53}$/(Ref https://pythonhosted.org/passlib/lib/passlib.hash.bcrypt.html#format-algorithm)A more general version of this would be password hashes in "modular crypt" format.
