Thanks James, I have updated the password of one user in galaxy_user table
with the new algorithm,
I also adjusted the function "new_secure_hash"
in /lib/galaxy/util/hash_util.py in such a way that it returns
the new hash instead of sha1. Now I tried to login, it fails to get the
account, I think there is something going
wrong in the password hash comparison. Can you please assit here.
