How to encrypt DATA.ini ?

[Tdi123]

I am looking to encrypt the data.ini to prevent players from making changes to the server, through grf customs.

Use Embedded GRF.. disable read data folder.. encrypt all your grf. done.

U can embedd it to ur executable or use a hackshield which generates a checksum/hash and check it every start. Gepard as example.

You could also just *not* use it. Uncheck the diff patch in NEMO for something like "Use multiple GRFs". That will force your client to use data.grf and rdata.grf, and maybe adata.grf, I think. You can then hex your client. Use GRF Editor to encrypt your GRF and produce a custom cps.dll and you should be a little safer if you're not going to use any client-side protection.

I can still modify the grf even though I don't have the password.

Yes, and the program allowed it!

I can replace a file or add it, the program allows it, even if I don't have the password

It's the files that are encrypted. You can overwrite them or add more files, but you can't extract the files without the password/key.
