What is @ethersproject/signing-key?

@ethersproject/signing-key is a part of the ethers.js library, which provides utilities for handling cryptographic signing keys. It allows you to create, manage, and use signing keys for cryptographic operations, particularly in the context of Ethereum and other blockchain technologies.

What are @ethersproject/signing-key's main functionalities?

Creating a Signing Key

This feature allows you to create a new signing key from a given private key. The SigningKey object can then be used for various cryptographic operations.

const { SigningKey } = require('@ethersproject/signing-key');
const privateKey = '0x0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef';
const signingKey = new SigningKey(privateKey);
console.log(signingKey);

Signing a Message

This feature allows you to sign a message using the signing key. The message is first hashed, and then the hash is signed to produce a signature.

const { SigningKey } = require('@ethersproject/signing-key');
const privateKey = '0x0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef';
const signingKey = new SigningKey(privateKey);
const message = 'Hello, world!';
const messageHash = ethers.utils.keccak256(ethers.utils.toUtf8Bytes(message));
const signature = signingKey.signDigest(messageHash);
console.log(signature);

Recovering a Public Key

This feature allows you to recover the public key from a signed message. This can be useful for verifying the authenticity of a message.

const { SigningKey } = require('@ethersproject/signing-key');
const privateKey = '0x0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef';
const signingKey = new SigningKey(privateKey);
const message = 'Hello, world!';
const messageHash = ethers.utils.keccak256(ethers.utils.toUtf8Bytes(message));
const signature = signingKey.signDigest(messageHash);
const recoveredPublicKey = SigningKey.recoverPublicKey(messageHash, signature);
console.log(recoveredPublicKey);
