I just got mcrypt support for my PHP:

    // Open the cipher
    $td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');

// Create the IV and determine the keysize length $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_DEV_RANDOM); $ks = mcrypt_enc_get_key_size ($td);

// Create key $key = substr (md5 ('very secret key'), 0, $ks);

// Intialize encryption mcrypt_generic_init ($td, $key, $iv);

// Encrypt data $encrypted = mcrypt_generic ($td, 'This is very important data');

// Show string echo trim ($encrypted)."\n";

// Terminate encryption handler mcrypt_generic_deinit ($td);

// Initialize encryption module for decryption mcrypt_generic_init ($td, $key, $iv);

// Decrypt encrypted string $decrypted = mdecrypt_generic ($td, $encrypted);

// Terminate decryption handle and close module mcrypt_generic_deinit ($td); mcrypt_module_close ($td);

// Show string echo trim ($decrypted)."\n";
