PHP AES128解密

Question

I used this Class to encrypt a NSString. I now need a PHP script to decrypt it again. How do I do that? Already tried this:

echo mcrypt_decrypt(MCRYPT_RIJNDAEL_128, "hi", base64_decode("XzFXgmIZmPF04CJDlUQ0eIoe47BUXTj3Am+86+QFo6A="),MCRYPT_MODE_ECB);

but it does not return anything.

Answer 1

解决了它，必须安装mcrypt...。
