Every know and then, I see someone complaining you cannot sell
programs written i Python or Java, because the bytecodes are so easily
reverse engineered. The same guys usually have no problem with C#,
because the executable are called 'something.exe'. The fact that
a .NET executable also contain bytecodes, seems to be of little
It is very easy to obfuscate Python bytecodes beyond normal
comprehension. All that is required is to put the .pyc files in a
zipped folder and encrypt it. Then it's a matter of triviality to
produce a C program that decrypts the zipped folder, embeds a Python
interpreter, and runs the decrypted program. But even this scheme is
not foolproof against an extremely skilled and determined adversary.
Nothing really is. What measures to take depend on the threat.
If the threat prevents distribution of code in any form, one can
always provide critical parts as a web service and distribute nothing
