So I'm trying to just hash some passwords in postgresql, and the only hashing solution that I've found for postgresql is part of the pgcrytpo package ( http://www.postgresql.org/docs/8.3/static/pgcrypto.html ) that is supposed to be in postgresql-contrib ( http://www.postgresql.org/docs/8.3/static/contrib.html ).
So I installed postgresql-contrib, (sudo apt-get install postgresql-contrib), restarted my server (as a simple way to restart postgresql).
However, I still don't have access to any of the functions for hashing that are supposed to be in postgresql-contrib, e.g.:
ninjawars=# select crypt('global salt' || 'new password' || 'user created date', gen_salt('sha256'));
ERROR: function gen_salt(unknown) does not exist
ninjawars=# select digest('test', 'sha256') from players limit 1;
ERROR: function digest(unknown, unknown) does not exist
ninjawars=# select hmac('test', 'sha256') from players limit 1;
ERROR: function hmac(unknown, unknown) does not exist
So how can I hash passwords in postgresql, on ubuntu?
