I have original file and compressed(+ maybe encrypted) file. Could someone take a look and even give me some idea what algorithm is used?
The structure of the encrypted file will probably (I'm not 100% sure) looks like this:
Im not expert about encryption, so I may be wrong ;)Code:4 bytes - signature
16 bytes - HMAC key
32 bytes -HMAC
4 bytes - orginial size
...to the end - content
