Use the following form to see the effects of PHP's md5, hash, and crypt functions:
<form action="crypt.php" method="post"> Word/Phrase/Text to be hashed: <input type="text" name="word" /> <input type="submit" value="Crypt it!" /> </form> <?php echo "md5 = {'" . md5($_POST['word']) . "'}<br />"; echo "hash = {'" . hash('sha512', $_POST['word']) . "'}<br />"; echo "crypt = {'" . crypt($_POST['word'], CRYPT_SHA512) . "'}<br />"; ?>
