I try using crypt/decrypt with GPG when login/logout. It works, but not safe enough.
what I did for a project I was working on was I create a LD_PRELOAD library which overloaded the i/o operations and used gz and bz2. This could easily be adapted to overload with encryption library functions rather than compression libraries. You can also use this to keep the bash history in memory using a shared memory location. As said in the rest of the thread this won't completely stop root, but it does make it more difficult. D. blaze your trail -- Daniël W.
