# py-ed25519-zebra-bindings — Python bindings for the ed25519-zebra RUST crate

License: permissive · Maintenance: active · Downloads: 265.1K/mo

## What it is and what it does

py-ed25519-zebra-bindings wraps the ed25519-zebra Rust crate to provide Ed25519 operations in Python. It exposes functions for deriving a keypair from a seed, signing a message with a private key, and verifying a signature against a message and public key. The bindings are compiled to native code, so installation requires a pre-built wheel for your platform or a local Rust build environment; wheels are available for Python 3.9, 3.10, 3.11, 3.12, and 3.13 across common architectures.

The package has no runtime dependencies and is designed for applications that need Ed25519 signatures—blockchain systems, cryptographic protocols, or any system requiring deterministic public-key signing. It is maintained as part of the Polkascan project and carries no known security vulnerabilities.

Use it for:

- Derive Ed25519 keypairs from seeds in blockchain or wallet applications.
- Sign transactions or messages in cryptocurrency or distributed-ledger systems.
- Verify cryptographic signatures in authentication or integrity-checking workflows.
- Integrate Ed25519 signing into Python applications requiring compiled-code performance.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to the ed25519-zebra Rust crate for Ed25519 digital signature operations—key derivation, signing, and verification.

Yes, if you need Ed25519 signing and verification in Python and can accommodate medium install friction. The package is actively maintained, carries no known vulnerabilities, uses a permissive license, and has no runtime dependencies. Install it if your use case requires deterministic Ed25519 operations; skip it if you prefer pure-Python alternatives.

## Install

pip install py-ed25519-zebra-bindings
uv add py-ed25519-zebra-bindings
poetry add py-ed25519-zebra-bindings

## Installing py-ed25519-zebra-bindings

Before you install: Medium install friction due to compiled wheels; pre-built binaries available for Python 3.9–3.13 on Linux (x86_64, aarch64, armv7l, ppc64le, i686), macOS (x86_64, arm64), Windows, and musl systems. Repository is active with recent commits.

License in practice: Licensed under Apache Software License (permissive); no restrictions on commercial or private use, modification, or distribution provided the license and copyright notice are retained.

Quickstart:

pip install py-ed25519-zebra-bindings

import py-ed25519-zebra-bindings

message = b"test"
private_key, public_key = ed_from_seed(seed_bytes)
signature = ed_sign(private_key, message)
if ed_verify(signature, message, public_key):
    print('Verified')

Requires Python 3.9 or later; seed derivation typically requires a separate BIP39 library.

Verify before relying:

- Exact API function names and signatures beyond what the description excerpt shows.
- Performance characteristics compared to pure-Python or other Ed25519 implementations.
- Whether the package is actively maintained beyond the last commit date (2026-06-15).
