only produces invalid keys

[Qwertylex]

i'm on linux 5.13.13 with GCC 11.1.0 and OpenSSL 1.1.1l 24 Aug 2021
compiled with gcc -lcrypto main.cpp
result:

any ideas why?

The code uses the long type, which is 32 bit on windows and 64 bit on linux.

FYI - I made a fork with the necessary changes here:

https://github.com/Neo-Desktop/WindowsXPKg

It does in fact compile and run correctly under linux. Haven't tried under mingw yet

The application does report that the keys generated are valid (server 2003 will occasionally generate an invalid key, probably due to it using an older algorithm)

@Neo-Desktop
Compiles without issue after installing libssl-dev on debian.
It generates codes but none are accepted in the XP installer on PRO and Home Premium 32bit.

The keys generated currently only work for the VLK editions of Windows XP

Ah... No problem, thanks for explaining. I used the windows xp_activate.exe to register the XPHP edition.
I found this referenced on Mastodon this morning so thought I'd give it a quick try.
