Hello all.
Has anyone ever tried to decode a JAVA AES/CBC encrypted string with PHP before?
I found a tutorial online with the following code to use as starting point, but it fails to return
anything readable:
$code ='Hello World';
$key = 'my key';
function decrypt($code, $key) {
$key = hex2bin($key);
$code = hex2bin($code);
$td = mcrypt_module_open("rijndael-128", "", "cbc", "");
mcrypt_generic_init($td, $key, "fedcba9876543210");
$decrypted = mdecrypt_generic($td, $code);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return utf8_encode(trim($decrypted));
}
function hex2bin($hexdata) {
$bindata = "";
for ($i = 0; $i < strlen($hexdata); $i += 2) {
$bindata .= chr(hexdec(substr($hexdata, $i, 2)));
}
return $bindata;
}
echo decrypt($code, $key);
The above returns output containing a series of unprintable characters.
I thought maybe it was due to $code not being in a hex format, but after converting to hex and
resubmitting, I still unprintable characters.
Any info is appreciated.
