The project allows to encrypt and decrypt text file by Cryptography based on delayed chaotic neural networks.
The secrete key of this cryptosystem is (g1, g2, a1, a2, T12, T21, k1, k2, and number of transient iterations N0) must be kept secrete.


The trajectory of state variables x1(t), x2(t) as below:
Iterate 100 times

Iterate 500 times

Iterate 1000 times

Iterate 10000 times

Python language with version 3.x
Then setup environment:
pip install numpy
pip install matplotlib

From terminal type following command line to run:

python3 main.py --type type-crypt --file path/to/filename/to/crypt

1. Change "type-crypt" to "enc" if you want to encrypt file, else "dec" to decrypt file.
2. Change "path/to/filename/to/crypt" to file name you want to do crypt
