PQencryption

A Python library for classical and post-quantum cryptography.

It wraps in one unified interface the following cryptographic mechanisms:

• AES256 encryption
• Salsa20 256 encryption
• McBits encryption
• SHA256 hashing
• Cryptographic key generation
  • Symmetric keys
  • Public/private keys
  • Signing/verification keys

Installation

• Install dependencies for pycrypto. For example in Ubuntu:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

• Set up a virtual python environment in the folder of your project.

pip install --user pipenv
pipenv --two shell

• Navigate to the root folder of this repository and install python dependencies from there. Also install the PQencryption package.

pipenv install
pipenv install ./PQencryption

Usage

Use the package as indicated in the file crypto_examples.py. Example for generating a public-private key pair:

from PQencryption import utilities
public_key, private_key = utilities.generate_public_private_keys()
