The only other relevant place is the User object in model/__init__.py -- James Taylor, Assistant Professor, Biology/CS, Emory University On Thu, May 2, 2013 at 6:46 PM, Vipin TS <vipin.ts@gmail.com> wrote:
I have updated the table schema from the script to adjust the column length from the following script: lib/galaxy/model/mapping.py
Now my new registration passwords are encrypted with second layer of authentication using PBKDF2 new entry from the database table:
galaxy=# select username,email,password from galaxy_user where email = 'vipin@mail.com'; username | email | password ----------+----------------+----------------------------------------------------------------------- | vipin@mail.com | PBKDF2$sha256$10000$lv0RfxbU3SymKvEA$l4RH9f9xHrH4pcf9n6ELP1MWjG+hooEW
BUT now I am experiencing the problem with authenticating the newly registered user name. once I log out, I can’t log back in again – password invalid. This tells me there is something going on with the password hash/compare function.
Can you please guide through the right module to look for this,
Will be quite helpful, --/Vipin
I have started testing with creating a new user and the password hash created using new algorithm,
galaxy=# select username,email,password from galaxy_user where email = 'fmlmpg@gmail.com'; username | email | password ----------+------------------+------------------------------------------ | fmlmpg@gmail.com | PBKDF2$sha256$10000$e0DVCuGEua3ebxxU$Bh6
I have updated the length of password column to 80 characters in my table and still the stored password seems to be in 40 char long, I print the hash after creating the second hash (password -> sha1 hash 40 char long-> pbdkf2 hash 69 char long)
before storing into the database table, I believing the hash has been truncated, any idea what is happening here. I am not seeing any clue in the code.
thanks, Vipin
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.

That should be the only place, it is called from the some methods of the User model object. So you could modify it to always hash new passwords in a different way, but check old passwords with sha1 first, then something else.
Although it might be nice to move the functionality into security.validate_user_input since it is really specific to user passwords, especially with those changes.
I'd be happy to see this go into main with sha256 or something similar. Also, we could consider adding a random per-user salt field if you are really concerned about this.

Hello dev-team, I would like to add the different type of password encryption to the users in my galaxy instance. I started working with the current password encoding script: /home/apps/galaxy-dist/lib/galaxy/util/hash_util.py
I will keep the current sha1 and add another layer of encryption to the sha1 hash, otherwise I need to force all my users to change the password and follow the new hashing method.
Can anyone please point me any other place/script which I missed regarding the encryption/decryption of user authentication.
thanks in advance, --/Vipin
