hash non-password php code example

Example 1: php hash password

<?php
/**
 * In this case, we want to increase the default cost for BCRYPT to 12.
 * Note that we also switched to BCRYPT, which will always be 60 characters.
 */
$options = [
    'cost' => 12,
];
echo password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options);
?>

Example 2: hash php

I was interested how "long" each hash is, so I did:



<?php

$data = "password";



foreach (hash_algos() as $v) {

        $r = hash($v, $data, false);

        printf("%-12s %3d %s\n", $v, strlen($r), $r);

}

?>



which produce (long hashes are cropped)
