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 = '
fml...@gmail.com';
username | email | password
----------+------------------+------------------------------------------
| fml...@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
