Now I am working with vortex wargame level14.
0000018:20fb 763e 64d3 72
0000032:20fb 763e 64d3 72
These bytes are the same, so I think it used some xor algorithm to encrypt.
0x32-0x18=0x1a
So the encryption key length is 13 or 26.
But I don't know what to do next.
Can someone give me some hint or just tell me the answer?
Thanks a lot!
