A dead simple tool to sign files and verify signatures

Project description

Minisign Python

This is a pure Python implementation of Frank Denis' minisign, following the specifications copied from there.
Currently following version 0.9.

IMPORTANT NOTE: this is currently under heavy development, and it hasn't undergone an external security assessment.


  • Compatible public interface: all commands and options must be 100% compatible and with same results.
  • Usage as CLI and as Python module.
  • Follow semver.

Secondary goals

  • Small amount of dependencies (I would love to keep it just to cryptolibraries).
  • If possible, maintain current active Python versions (3.7+).


  • Define goals and license.
  • Create initial project structure.
    • Code structure.
    • Contribution guidelines.
    • Pipeline.
  • Achieve basic functionality:
    • Create key pair.
    • Verify signature.
    • Sign.
  • Ensure coverage 100%.
  • Make first release.
  • Add remaining options.


  • Python 3.7+
  • PyNaCl 1.3+
