[galaxy-dev] best practice to replace the hashing for galaxy-user passwords

Dear dev-team, I am interested to implement the secure hashed password specifically SHA-256 or greater to the galaxy users using publicly available python module PBKDF2. I have a piece of python code which will do the job but not quite sure how I can integrate this to my local galaxy code repository. I saw the current implementation in galaxy/util/hash_util.py any suggestions, thanks, --/Vipin
