I had some problems using the examples on mcrypt, so I wrote this class which is derivative of (paul
at xmill dot com)'s example:
*note that this example uses PHP 4.1.2 with lib mcrypt 2.5.x
<?php
class crypto_class {
function encrypt($string,$password) {
$td = mcrypt_module_open (MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, "");
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND);
mcrypt_generic_init ($td, $password, $iv);
$encrypted = mcrypt_generic ($td, $string);
mcrypt_generic_end ($td);
return($encrypted);
} // end encrypt
function decrypt($encrypted,$password) {
$td = mcrypt_module_open (MCRYPT_TripleDES, "", MCRYPT_MODE_ECB, "");
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND);
mcrypt_generic_init ($td, $password, $iv);
$decrypted = mdecrypt_generic ($td, $encrypted);
mcrypt_generic_end ($td);
return($decrypted);
} //end decrypt
} // end crypto_class
$crypto = new crypto_class;
$encrypted = $crypto->encrypt('passwordx','good2Go123');
$decrypted = $crypto->decrypt($encrypted,'good2Go123');
print "$encrypted<br>\n";
print "$decrypted<br>\n";
?>
