What the decrypt method for AES/CTR/NoPadding ?

[ffcactus]

Java client send the encrypted message by using

import package javax.crypto.Cipher;

val cipher = Cipher.getInstance("AES/CTR/NoPadding");

It should be one of the following, I'm not sure which one Java uses by default here. It should be easy enough to test with an encrypted payload at https://playground.vrl.dev/ (VRL runs client side here, but please don't submit secrets just to be safe)

AES-256-CTR
AES-192-CTR
AES-128-CTR

None of these might actually work, it seems like Java uses a different "endianness" than VRL currently supports. More info here: #297

Yes, VRL uses a different endian than most of the libraries. I hope it can be fixed soon. Thank you.
