This project is an simple example of creating somewhat homomorphic solution, that allows encryption, decryption, and homomorphic addition conducted on integers.
Python 3.x and git are prerequisites. To run project using bash:
git clone https://github.com/jawoszek/homomorphic-ciphers.git
cd homomorphic-ciphers/
export PYTHONPATH=`pwd`
python3 tests/test_somewhat_homomorphic.py
Execution of the test suite above should take around 3-5 minutes, depending on CPU.
