I share whit all sm users a serial validation kit.
I'ts a simple thing. this tools is useful for who want to make a serial validation or a serial key/password matcher.
Ok. How it works?
1) load a serial or password txt where keys are one x line
2) load a serial or password txt where keys are one x line that you want to match with the first.
if XXXX-XXXX-XXXX is on the first line of first key txt you'll see the 1st line of the second text (validation).
You would'nt see anything if keys does not match.
here an image:paid attention
If you use this for serial changes or validation you have to know that is not secure. maybe some people would reverse the code and extract the serials.
