anproto-rs

Rust implementation of ANProto: the Authenticated and Non-networked protocol or ANother protocol.

Description

ANProto is a protocol for authenticated, non-networked messages using ed25519 signatures, timestamps, and SHA-256 hashes, all base64-encoded.

Usage

Add to your Cargo.toml:

API

• gen() -> Result<String, String>: Generates an ed25519 keypair, returns base64(public + secret).
• hash(data: &str) -> String: Computes SHA-256 of data, returns base64 hash.
• sign(hash: &str, key: &str) -> Result<String, String>: Signs (timestamp + hash) with the secret key, returns base64(public + signature + timestamp + hash).
• open(signed_message: &str) -> Result<String, String>: Verifies the signature and returns (timestamp + hash) if valid.

Example

Run the example:

cargo run --example example

This matches the output of the JavaScript implementation in ANProto/node_ex.js.

Testing
