You have two options here: 1) Use a strong encryption like aes256 etc and don't bother trying to "hide" the code because it's just a blob of data and they'll not crack it. 2) Encrypt the whole drive if you use something like *nix/*bsd. The only thing hiding the code will do is make them guess at the method. But if you use a good method in the firstplace, you shouldn't have any issues because it's not going to be cracked. > I *could* write a C program which just exec()'s the required programs, > if they're done separately this would be fairly well hidden but I was > wondering if there's anything more obvious I can do that enables me to > do things easily in Python. > > > This is for protecting against any possible intruder who has gained > access to my system by breaking an ssh password or stealing my laptop > for example.
