05. Sep 2005		Here is a full keygen..Call void BruteForce(argument) multiple times with different inputs.
However, you would need to change a few things here and there to make it compatible with C++ ( I dont have VC++ here so I couldnt put the final touch into it )


void BruteForce(long Parameter1);
{
CP = 64bitEncryption(Parameter1, long(73h+76h+85h+94h+0ADh+0EFh+0DFh+0CBh+0DAh+75h+84h+23h+91h+0CDh+0FBh));

i = 0;
C = 4;
do
{
if (C==0) {C=4} // cl switches between 0 and 4
else if (C==4) {C=0}
ecx = (i & 1) << 2;
A = i >> 1;
if (signed && carry) { A += 1 }
if (!signed) {
param = *(A + Parameter1) >> C & 15;
i += 1;
CP[i] = param + 97;
}
} while(i < 15);

bFail = false;
I = 0;
for(*char = "pinemfjelaciebhk"; 1; char++) {
if(char == null) {
break;
}
if(char != CP[I]) {
bFail = true;
}
CP += 1;
I++;
}
if (!bfail)
MessageBoxA(0, "Working Password: "+Parameter1, "BieXs Keygen", null);
}


long 64bitEncryption(pointer *encInput, pointer *memArea)
{
smallint bits;
smallint hexVal;
smallint hex2;
long mem;
long out2;
long out;

mem = memArea;
out2 = *(encInput + 4);
out = *encInput;
hex2 = 0;
hexVal = 0x9E3779B9;
bits = 64;
bits = bits + (-1);

while (bits > 0) {
hex2 = hex2 + hexVal;
out = out + ((((out2 << 4) + *mem) ^ (hex2 + out2)) ^ ((out2 >> 5) + *(mem + 4)));
out2 = out2 + ((((out << 4) + *(mem + 8)) ^ (hex2 + out)) ^ ((out >> 5) + *(mem + 12)));
bits--;
}

*encInput = out;
out = encInput;
*(out + 4) = out2;
return (out);
}

05. Sep 2005		Or you can choose the easy way and reverse the algo :D and solve it without killing you CPU

05. Sep 2005		yup yup, but that is not bruteforceing :P
