zapple what you get is a slap around the back of the head lol !
i had to give you the answer grrrr

the whole point of this was to download the program then disassemble & brute force it (ie a test of your cracking skills)

i think tank should get most credit , he got the closest by writing some programs to check the results of the decryption

i must admit that by making the decrypt.exe program a dos application made it a little harder to crack but there are plenty of free dos disassemblers out there oh well
( at a pinch you could even use debug.exe that comes with windows ! )

next time

i'll make it easy

btw the posted pic didnt display

can you re-post it (maybe you should keep it as bmp and not change it to gif ? although i cant see why that should cause a problem unless you just renamed it to gif ?)

===============================================
heres the source code of decrypt.exe in case anyone is interested ?
===============================================

uses
crt, dos;

var
filein : file of byte;
fileout : file of byte;

x, y : integer;
databyte : byte;

seed : word;

begin

clrscr;
textcolor(white);
writeln(' __________________________________________ ');
textcolor(lightcyan);
writeln(' / \_ ____/_ ____/_ _ \_ __ \_ __ \ ');
textcolor(lightblue);
writeln('/ / /____/ ___/_/ / / / ___ / / / / ');
textcolor(blue);
writeln('\_/\______/\______/\_/\_/\_/\_/ \_/\_/ \_/ ');
writeln;
writeln;

textcolor(white);
write('Enter decryption code : '); readln(seed);

assign(filein, 'crypted.bmp'); reset(filein);
assign(fileout, 'decrypt.bmp'); rewrite(fileout);

for x := 0 to $435 do
begin
read(filein, databyte);
write(fileout, databyte);
end;

randseed := seed;

for x := 0 to 159 do
for y := 0 to 159 do
begin
read(filein, databyte);
databyte := databyte xor random($100);
write(fileout, databyte);
end;

close(fileout); close(filein);

end.

I deleted Free's second post, not realizing that it would remove the picture file that the first post was referencing.

While the picture was there it displayed fine.

My bad.
