Creating a private python interpreter using opcode permutation strategy
(A clear and concise description of your proposal.)
I want to create a private python interpreter by exchanging opcodes , aims to increase the difficulty of cracking the pyc file, we make a private python environment(private python)。
I made a little attempt first and I tested is 3.9.6:
swap the opcode of the two operations of BINARY_ADD and BINARY_SUBTRACT's opcode
My modification policy has the following three places:
1.Include/opcode.h：swap bytecode definitions:

2. Lib/opcoe.py: exchange the opcode:

3.Python: opcode_targets .h: swap the order of the two opcodes in the swap

I would appreciate it if someone can provide me with some help
