Crate alloy_signer_local 

alloy-signer-local

Local signer implementations:

• K256 private key
• Secp256k1 private key (feature-gated)
• Mnemonic phrase
• YubiHSM2

Features

• keystore: enables Ethereum keystore functionality on the PrivateKeySigner and Secp256k1Signer types.
• mnemonic: enables BIP-39 mnemonic functionality for building PrivateKeySigners.
• secp256k1: enables the Secp256k1Signer type, an alternative signer implementation using the secp256k1 crate instead of k256.
• yubihsm: enables LocalSigners with YubiHSM2 support.

Secp256k1 vs K256

This crate provides two ECDSA implementations:

• PrivateKeySigner (default): Uses the k256 crate, a pure Rust implementation.
• Secp256k1Signer (feature-gated): Uses the secp256k1 crate, Rust bindings to libsecp256k1.

Both implementations produce identical signatures and addresses for the same private key. The secp256k1 crate may offer better performance in some scenarios due to its optimized C implementation.
