Add salt to user passwords
|Category:||Accounts / authentication|
User passwords are stored as
SHA1(password) which makes them vulnerable to a dictionary attack from an attacker who gets access to the database.
The change consists of generating a salt for each user and storing
SHA1(salt+SHA1(password)) in the database.

So now if attacker gets hold of the database all he has to do is to remove leading salt (since salt is stored in DB) and proceed with the dictionary attack. I don't see how this makes password any more secure...
I take it all back. I didn't see salt+password_hash is hashed again.. my bad :F
