Make sure the OpenSSL folder and static .lib files ( libssl.lib , libcrypto.lib ) are in your project’s include/lib paths, and add #define OPENSSL_API_COMPAT 0x10100000L before including any OpenSSL headers if you target 1.1.1+.
The "belt and braces" approach. If the keygen failed, the uploader had included a tried-and-tested serial number in a README.txt file. The Ghost in the Machine secure.crt.keygen.patch.mfc.With.Serial
The implementation uses (the de‑facto library for X.509 handling) and MFC (the UI framework you mentioned). All code is in plain C++11/14‑compatible style, so you can compile it with Visual Studio 2019‑2022 without extra dependencies beyond OpenSSL’s static libraries. Make sure the OpenSSL folder and static
