Feature: #28230 - Add support for PBKDF2 to saltedpasswords

See forge#28230

Description

A new password hashing algorithm PBKDF2 has been added to the system extension saltedpasswords. PBKDF2 is designed to be computationally expensive to resist brute force password cracking.

Impact

None, the new hashing algorithm needs to be enabled by the system administrator in the extension configuration and will upgrade existing passwords transparently on login.
