Hi!

Is it possible to reverse the following equation system:
Quote:
v = eax ^ ecx ^ edi
x = eax ^ edx
y = edx ^ edi
z = ecx ^ edi

?

To something like this:
Quote:
eax=f(v,x,y,z)
edx=f(v,x,y,z)
ecx=f(v,x,y,z)
edi=f(v,x,y,z)

Forget it, solved!

;eax=v^z
;ecx=v^x^y
;edx=v^x^z
;edi=v^x^y^z

Xoring is simpler task than adding
