Ed25519 public-key signatures (BLAKE2b fork)
Decision gist · record as of 2026-08-14
Yes, if you need Ed25519 signatures with BLAKE2b for NANO or a compatible system. The package is actively maintained, has no known vulnerabilities, and uses a permissive license. Install friction is moderate due to C compilation, but prebuilt wheels cover common platforms. Verify that this fork is the recommended version for your use case, as the repository has minimal visibility (1 star).AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a C compiler if building from source; prebuilt wheels available for Python 3.10–3.11 on major platforms.
- Medium install friction due to C compilation requirement, but prebuilt wheels are available for common platforms (Python 3.10–3.11 on macOS, Linux, Windows, and musl).
- Repository is active with a recent commit.

What it is and what it does
This package wraps a C implementation of Ed25519 digital signatures, modified to use BLAKE2b as the hash algorithm instead of SHA512. It allows you to create signing and verifying keypairs, sign messages deterministically, and verify signatures. The underlying C code is from the SUPERCOP benchmark suite and is in the public domain; the Python binding is MIT-licensed.
The package is designed for systems like NANO that require Ed25519 signatures with BLAKE2b hashing. Keys and signatures are compact (32 bytes for keys, 64 bytes for signatures), and operations complete in milliseconds. It provides both binary and ASCII-encoded (base64, base32, base16, hex) interfaces for keys and signatures, making it easy to serialize and transmit them.
Use it for
- Sign and verify messages in NANO or other systems that require Ed25519 with BLAKE2b hashing.
- Generate and manage Ed25519 keypairs for cryptographic protocols that need deterministic signatures.
- Serialize public keys and signatures to ASCII formats for storage in JSON, configuration files, or over text-based protocols.
- Derive signing keys from existing secrets by providing a 32-byte seed.
- Verify message authenticity in distributed systems or peer-to-peer applications.
