Crate gsigner 

Source
Expand description

Universal cryptographic signer library supporting multiple signature schemes.

This crate provides a unified interface for cryptographic signing operations supporting secp256k1 (Ethereum), ed25519, and sr25519 (Substrate) signature schemes.

§Features

  • secp256k1 - Enable Ethereum/secp256k1 ECDSA support (enabled by default)
  • sr25519 - Enable Substrate/sr25519 Schnorrkel support (enabled by default)
  • ed25519 - Enable Substrate-compatible ed25519 support (enabled by default)
  • cli - Enable command-line interface tools
  • codec - Enable parity-scale-codec support for serialization
  • keyring - Keyring support with primary key management
  • gprimitives - Enable gprimitives integration (for ActorId conversions)
  • alloy-primitives - Enable alloy-primitives integration
  • sp-core - Enable sp-core integration (Substrate compatibility)
  • sp-runtime - Enable sp-runtime integration (Substrate compatibility)

§Examples

ⓘ
use gsigner::secp256k1;

// Create an in-memory signer
let signer = secp256k1::Signer::memory();

// Generate a new key
let public_key = signer.generate()?;

// Sign some data
let signature = signer.sign(public_key, b"hello world")?;
