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.
