bc-lifehash-python - The python implementation

LifeHash is a method of hash visualization. This is a python implementation of bc-lifehash, see there for an overview of LifeHash.

This python library should probably be replaced with bindings to the C implementation, which is the "canonical" reference implementation.

Dependencies

This LifeHash library is self-contained and has no dependencies.

Installation

$ pip3 install lifehash

Use

from lifehash.lifehash import LifeHash, LifeHashVersion
image = LifeHash.make_from(b"hello world", version=LifeHashVersion.version2, module_size=1, has_alpha=True)

Testing

$ python3 -m unittest lifehash/lifehash.py

Building

$ python3 -m build

For releases: git tag and push, then twine upload dist/*

Discussions

The best place to talk about Blockchain Commons and its projects is in our GitHub Discussions areas.

Wallet Standard Discussions. For standards and open-source developers who want to talk about wallet standards, please use the Discussions area of the Airgapped Signing repo. This is where you can talk about projects like our LetheKit and command line tools such as seedtool, both of which are intended to testbed wallet technologies, plus the libraries that we've built to support your own deployment of wallet technology such as bc-bip39, bc-slip39, bc-shamir, Sharded Secret Key Reconstruction, bc-ur, and the bc-crypto-base. If it's a wallet-focused technology or a more general discussion of wallet standards,discuss it here.

Blockchain Commons Discussions. For developers, interns, and patrons of Blockchain Commons, please use the discussions area of the Community repo to talk about general Blockchain Commons issues, the intern program, or topics other than the Gordian System or the wallet standards, each of which have their own discussion areas.

Other Questions & Problems

As an open-source, open-development community, Blockchain Commons does not have the resources to provide direct support of our projects. Please consider the discussions area as a locale where you might get answers to questions. Alternatively, please use this repository's issues feature. Unfortunately, we can not make any promises on response time.

If your company requires support to use our projects, please feel free to contact us directly about options. We may be able to offer you a contract for support from one of our contributors, or we might be able to point you to another entity who can offer the contractual support that you need.
