ECC-ECDHE-Chat-Example

Example of the ephemeral form of ECDH exchange with forward secrecy

Features

• Re-usable core crypto module
• ECDH Exchange (+ Key derviation) with manual key rotation for ephemeral encryption
• AES Encryption/Decryption
• CLI UI

Future

• (In progress) Session management
• (TODO) Semi-auto exchange using tunnels (peer-to-peer)
• (TODO) GUI

Prerequisites

1. pip install cryptography
2. python main.py

Usage

1. Share your pubkey to your peer (end party)
2. Enter your peer pubkey to terminal input
3. Use encrypt to encrypt your text message, decrypt to decrypt, rotate to rotate keys
