neuron-crypto

Cryptographic provider traits for neuron — signing and verification

Overview

neuron-crypto defines the CryptoProvider trait for signing and verifying data within the neuron system. It provides an abstraction over key material and signing backends, keeping the operator code independent of whether keys are held in software, a hardware token, or a remote KMS.

This crate contains no implementations — for concrete providers see the backend crates:

Usage

[dependencies]
neuron-crypto = "0.4"

Implementing a custom crypto provider

use neuron_crypto::{CryptoProvider, SignatureBytes};
use async_trait::async_trait;

pub struct MySigningProvider;

#[async_trait]
impl CryptoProvider for MySigningProvider {
    async fn sign(&self, data: &[u8]) -> Result<SignatureBytes, neuron_crypto::CryptoError> {
        // sign data with your key
        todo!()
    }

    async fn verify(&self, data: &[u8], sig: &SignatureBytes) -> Result<bool, neuron_crypto::CryptoError> {
        todo!()
    }
}
