I just made a simple "encryption" cause I'm tired as ****.
Pretty much, take a look at ThievingSix's tutorial for information about encryption, I'm just breezing over what you need to do on editing your launcher.
Before I begin, I'm going to show you my text document which has the original part and the edited part:
When you look in the launcher, you won't see the encryption algorithm - but the decryption algorithm. What does that tell you? It means it "decompiles" the .mrs file to check it's CRC32 for updates. Just take what's in your runnable (the decryption part lmao) and do it in the launcher. Example:
D_D Just edit the parts in the launcher to fit your encryption, save, tada.
Edit- I can't guarantee this will work (Auto-Update didn't work and as I said, I'm tired.) and I can't guarantee the edited "decryption" algorithm will work. But with reason and logic being in what I just said, I can say with a 90% positive attitude it will work.
