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. --Rick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
