您的解密例程代码适用于我:public function decrypt($data, $key) {
$salt = substr($data, 0, 128);
$enc = substr($data, 128, -64);
$mac = substr($data, -64);
list ($cipherKey, $macKey, $iv) = $this->getKeys($salt, $key);
if ($mac !== hash_hmac('sha512', $enc, $macKey, true)) {
return false;
}
$dec = openssl_decrypt($enc, $this->cipher, $cipherKey, OPENSSL_RAW_DATA, $iv);
return $dec;}测试:$keys = [
'this is a secret key.',
'G906m70p(IhzA5T&5x7(w0%a631)u)%D6E79cIYJQ!iP2U(xT13q6)tJ6gZ3D2wi&0")7cP5',
chr(6) . chr(200) . chr(16) . 'my key ' . chr(3) . chr(4) . chr(192) . chr(254) . ' zyx0987!!',
'and finally one more key to test with here:',];$data = [
