Anyone who has seen this incredible compression? It comes from an unpublished game. I got it with a little trick. But it's different from any unit asset I've ever seen before. I tried XOR but it didn't work. The only unencrypted one is unity default resources, from which I can see the unit version. Who has seen such a document? Finally, please forgive my English. It's not my mother tongue.

If it is encrypted, you'll probably need the "Assembly-CSharp.dll" file of the game (maybe other files too) to get the encryption key.

Is a 64-bit XOR,I done. But thank you.

Do you mean a byte-per-byte XORing with a 64bit number generated with a pseudo-random algorithm and an initial seed?

Like:

Code:

srand(123);
for(i = 0; i < size; i  ) {
  data[i] ^= rand();
}
