Hello, I'm going to work on implementing crypting support for the packaged executable. The idea is that the .pyc files will be crypted with a simmetric cipher (say, Rijndael/AES) and the bootloader will use an external key to decrypt and run the executable. Fair warning: I'm *no* crypt expert.
Open issues (suggestions are welcome): - How key feeding should work? My current plan is to require a file called "executablename.key" in the same directory of the executable, containing the key in a text format (it's going to be 128/192/256 bits, or so). I was thiking of something like a .ini format. Of course, users can always customize the bootloader themselves for specific uses, so I'm just looking for a generic good-enough solution. Also additional program-specific information can be stored in the .ini file. - Should we crypt only .pyc/.pyo files or also .pyd/.so/.dll? Besides speed issues which I don't consider very important (since block ciphers are pretty fast), I am a little worried about secutiry holes. The plaintext version of most binary files could be easily found (say, all the standard modules shipped with Python) so this could compromise the key. Maybe this could be made an option. -- Giovanni Bajo _______________________________________________ PyInstaller mailing list PyInstaller@lists.hpcf.upr.edu http://lists.hpcf.upr.edu/mailman/listinfo/pyinstaller
