so i'm trying to write a keygen to a crack me that i learn from i got stuck so what happens there is pretty simple:

lets say that i inserting the password of "12121212"

XOR DWORD PTR DS:[ECX+EAX],1234567
AND BYTE PTR DS:[ECX+EAX],0E
ADD ECX,4
CMP ECX,8

So as we can see here the first DWORD is being Xor'ed with 0x1234567 so it turns to 0x56771233

Then ther is a AND operation over the first byte so 0x56 turns to 0x6

After that we move to the second DWORD and it dose this again so everything is good until now.

My question is i know i can inverse XOR but is it possible with AND ?
