pytezos-crypto

This is a friendly fork of the crypto module from the pytezos project, containing only the cryptographic utilities from the upstream repository, located at pytezos/crypto.

Motivation

The purpose of this fork is to provide the cryptographic functionalities of pytezos while keeping dependencies to a minimum. The upstream project includes a large number of additional dependencies such as Jupyter Notebook which are unnecessary for those seeking only the cryptographic utilities. This fork extracts the core crypto functionality and eliminates non-essential dependencies.

Approach

This project is not intended to diverge from the upstream. Please submit all proposed changes to the upstream project first, and only open Pull Requests here after those changes have been accepted upstream.

Installation

pip install aleph-pytezos

Dependencies

This fork only includes the essential cryptographic dependencies:

• base58
• importlib-metadata
• mnemonic
• pynacl
• python-magic
• coincurve
• typing_extensions
• fastecdsa
• pysodium

Comparison with Upstream Dependencies

The upstream pytezos project has a much broader set of dependencies, supporting a variety of additional features beyond cryptography, including container management, CLI tools, and notebook integrations. Here is a breakdown of the differences:

Dependencies in pytezos-crypto (this fork):

• base58
• importlib-metadata
• mnemonic
• pynacl
• python-magic
• coincurve
• typing_extensions
• fastecdsa
• pysodium

Additional Dependencies in the Upstream Project:

• Python version constraint: python >= 3.8.1
• CLI and utility dependencies:
  • click
  • tqdm
• Development and container-related tools:
  • docker
  • notebook
  • testcontainers
• Data manipulation and validation libraries:
  • attrs
  • cattrs
  • jsonschema
  • simplejson
  • strict-rfc3339
  • tabulate
• Cryptography-related extensions:
  • cryptography
  • py-ecc
  • deprecation
  • ply
• Networking and API libraries:
  • requests
  • netstruct
  • python-dateutil
• Specialized serialization:
  • simple-bson

The upstream project is suited for broader use cases such as Tezos contract management, testing, and development environments, which require additional dependencies. In contrast, pytezos-crypto focuses strictly on cryptographic functionalities, reducing complexity and improving performance for users needing only the core cryptographic tools.
