erro com mcrypt

[Hugo Borges_120734 6]

Galera usei o seguinte código para testar o mcrypt:

<?php
/*
* PHP mcrypt - Basic encryption and decryption of a string
*/
$string = "hugoborges";
$secret_key = "dt4239#e%@13ffdg!3%$^%*";
 
// Create the initialization vector for added security.
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND);
 
// Encrypt $string
$encrypted_string = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $secret_key, $string, MCRYPT_MODE_CBC, $iv);
 
// Decrypt $string
$decrypted_string = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $secret_key, $encrypted_string, MCRYPT_MODE_CBC, $iv);
 
echo "Original string : " . $string . "<br />\n";
echo "Encrypted string : " . $encrypted_string . "<br />\n";
echo "Decrypted string : " . $decrypted_string . "<br />\n";
?>

E retorna este erro:

Warning: mcrypt_encrypt(): Key of size 15 not supported by this algorithm. Only keys of sizes 16, 24 or 32 supported in /Applications/XAMPP/xamppfiles/htdocs/CoÌpia de 1.php on line 12

Warning: mcrypt_decrypt(): Key of size 15 not supported by this algorithm. Only keys of sizes 16, 24 or 32 supported in /Applications/XAMPP/xamppfiles/htdocs/CoÌpia de 1.php on line 15
Original string : hugoborges
Encrypted string : 
Decrypted string : 

Dei uma olhada no meu phpinfo(); e parece tudo ok:

Alguém sabe o que esta errado?

O erro te diz tudo.

O algoritmo exige chave de 16, 24 ou 32 caracteres. Você usou 15. Apenas adicione um caractere a mais à chave
