hexafid 0.7.5

The Hexafid Cipher reference implementation

Hexafid

Hexafid is an experimental block cipher. DANGER!

The project goals are to produce a cipher that:

• works easily with pen and paper
• secures confidentiality of information
• offers plausible deniability if discovered
• exhibits greater strength in software

Caveat Emptor

• Hexafid began as a hobby project during the COVID-19 pandemic
• The work has NOT yet been peer reviewed by the academic community
• The algorithms have NOT yet been proven to have strong security
• The software is released under an open source licence (MIT) that:
  • Limits ANY liability, and
  • Provides NO warranty

Installation

Use the package manager pip to install hexafid.

$ pip install hexafid

Usage

As an end user:

$ hexafid --version
$ hexafid --help
$ hexafid

As a developer:

from hexafid import hexafid_core as hexafid
hexafid.encrypt(message, key, mode, iv, period, rounds)  # returns ciphertext string
hexafid.decrypt(message ,key, mode, period, rounds)  # returns plaintext string

NOTE: use of these libraries assumes that you understand the cryptographic implications of changing parameters.

Contributing

Merge Requests are welcome. For all changes, please:

1. open an Issue first to document the activity;
2. label the Issue (e.g. Bug, Feature, Refactor, Suggestion, Test);
3. update or add any related tests to support your work;
4. create an associated Merge Request to discuss changes with a maintainer.

We expect team members to have minimum knowledge as found in https://www.coursera.org/learn/crypto.

Key areas of future research and development include:

1. linear and differential cryptanalysis
2. constraint optimized key search algorithm
3. publishable reference implementation in C
