Most of the time PHP developers encrypt password with MD5. But this days we need more secure encrypted  password.

Bellow I will show how to use SHA256 encryption method to create secure password hash.

We just need  two simple function:

First function genenrate_salt create a random string which will be used as salt for password hashing and function genenrate_password   do the rest

<?php

function genenrate_salt(){
$rndstring = "";
$length = 64;
$a = "";
$b = "";
$template = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
settype($length, "integer");
settype($rndstring, "string");
settype($a, "integer");
settype($b, "integer");

for ($a = 0; $a <= $length; $a++) {
$b = rand(0, strlen($template) - 1);
$rndstring .= $template[$b];
}

return $rndstring;
}

function genenrate_password($salt,$pass){
$password_hash = '';

$mysalt = $salt;
$password_hash= hash('SHA256', "-".$mysalt."-".$pass."-");

return $password_hash;
}

$salt = genenrate_salt();
$plain_pass = "hello123"; /* any password/text collected from user input */

echo "My Hash Password Is: ".genenrate_password($salt , $plain_pass);

?

Hope this will help some one.
