Hi I have this code that encrypts password and/or username. I'm trying to learn a better way of coding so I ask this question and sorry If this is one of those elementary questions.
I followed this steps stated in another post This one and I want to display (for testing purposes only if what I did was right) It does not need to be username or password, just a plain text inserted in an input box will do as long as I can see if what i entered is encrypted using my code. Please help me out. Stuck for like forever in this scenario.
Now here's my code.
MCrypt.php(just copied it)
<?php
class MCrypt
{
private $iv = 'fedcba9876543210'; #Same as in JAVA
private $key = '0123456789abcdef'; #Same as in JAVA
function __construct()
{
}
function encrypt($str) {
//$key = $this->hex2bin($key);
$iv = $this->iv;
$td = mcrypt_module_open('rijndael-128', '', 'cbc', $iv);
mcrypt_generic_init($td, $this->key, $iv);
$encrypted = mcrypt_generic($td, $str);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return bin2hex($encrypted);
}
function decrypt($code) {
//$key = $this->hex2bin($key);
$code = $this->hex2bin($code);
$iv = $this->iv;
$td = mcrypt_module_open('rijndael-128', '', 'cbc', $iv);
mcrypt_generic_init($td, $this->key, $iv);
$decrypted = mdecrypt_generic($td, $code);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return utf8_encode(trim($decrypted));
}
protected function hex2bin($hexdata) {
$bindata = '';
for ($i = 0; $i < strlen($hexdata); $i += 2) {
$bindata .= chr(hexdec(substr($hexdata, $i, 2)));
}
return $bindata;
}
}
?>
Here's my submit .php which I don't know if it's correct or not but when I try it show these error

$encrypted = $mcrypt->encrypt('fruit1');
