password_hash.php

<?php
//create random hash, please notice $6$ as first chars in salt string
$salt = "$6$5e2de398074f9213";
$hash = crypt('pswt1', $salt);
echo $hash;

//mariaDB compatible code: select ENCRYPT('pswt1', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16)));

echo "<hr>";

if (password_verify('pswt1', $hash)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}
echo "<hr>";

//second method, not recommended

$storedHash = password_hash(hash('sha512', "gigi", true), PASSWORD_DEFAULT);
echo $storedHash;

if (password_verify(hash('sha512', "gigi", true), $storedHash)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}
?>

First method offers sha-512 hash.
