McEliece cryptosystem implementation



Usage:

0. pip install numpy and galois

1. generate.py - generate and save public and private keys

2. send pubkey.py and encode.py to your friend

3. your friend runs encode.py, write secret string and send message.py to you

4. decode.py - get secret string



Hacker can get your private key if he will know a half of it (and pubkey.py, decode.py and Reed-Solomon algo).

Check break.py to understand how hacker can do this.



todo: check randomization during encode (add vector z, check https://en.wikipedia.org/wiki/McEliece_cryptosystem)
