I'm still working on my new tool, rKeyGen a key licensing system, including a key-generation tool and a key-validation library. It's been about 24 days working on it and not ready yet... import/export files, command line, testing... making software takes lot of time... 😖

When you open it, it needs to play this song

If it's a MOD/XM file, raylib can play it, actually my rInstallFriendly tool supports creating installers with this kind of background music.

needs chiptunes

This is awesome.

This is great!

RCA/ECC kind?

Symmetric, XChaCha20+Poly1305 for data encryption + key stretching

Looks awesome and I admire the effort, but aren't keys considered to be ineffective DRM?

Yeah, probably, all offline licensing systems could be hacked but still not that easy or impractical for most users, specially for companies licensing software.

Yes it does, I've been making a tiny HTTP library with Odin for two weeks now, so can relate hehe, btw the tool is looking great, will it be available for purchase at raylibtech?

Thanks, still some work left, there is a "special" feature not shown in the video. rKeyGen will be available for purchase and rkls, the keys validation library will be free and open source.
