install

python -m venv .venv
source .venv/bin/activate
pip install -e .

run tests

pip install pytest

run linear and differential bias empirical tests

in the venv

derive lookup tables

run sagemath script

deactivate the venv first, then with sagemath installed:

./run_sage.sh

Modes are:

1. Classic inspection
2. Advanced inspection with forced 0 or 1 bits
3. Exhaustive variable-change search
4. S box analysis
5. Variable XOR
6. F31, F32 analysis
7. Exhaustive XOR search
8. Cube attack search
9. Precompute and save model
10. Load model

n steps can be precomputed and then loaded for the offline part of the cube attack with the menu entry 9 and 10.
