I believe you forgot the salt. Traditionally, Unix adds an additional value to 
the password before it is encrypted. I don't know where that comes from.

[PHP] hash problem.

2010-07-29 Thread Jo�o C�ndido de Souza Neto 
I´ve got the setting in my /etc/login.defs file as bellow:

# Use MD5 or DES to encrypt password? Red Hat use MD5 by default.
MD5_CRYPT_ENAB no

ENCRYPT_METHOD SHA512

So, when I try to get this:

echo hash("sha512", $_POST["password"]);

It does not match the password the user´s got in /etc/shadow file.

Anyone knows why?
