What is ethereum-cryptography?

The ethereum-cryptography package provides a set of cryptographic functions that are commonly used in Ethereum-related projects. It includes functionalities such as hashing, key derivation, and signature verification, which are essential for creating and managing Ethereum wallets, signing transactions, and ensuring secure communication within the Ethereum network.

What are ethereum-cryptography's main functionalities?

Keccak-256 Hashing

This feature allows you to compute the Keccak-256 hash of an input, which is a common cryptographic hash function used in Ethereum for various purposes, including hashing transaction data.

const { keccak256 } = require('ethereum-cryptography/keccak');
const hash = keccak256(Buffer.from('hello'));

Public Key Recovery

This feature enables the recovery of a public key from a signature, which is useful for verifying the signer of a message or transaction in Ethereum.

const { ecdsaRecover } = require('ethereum-cryptography/secp256k1');
const publicKey = ecdsaRecover(signature, recovery, hash, compressed);

BIP39 Mnemonic Generation

This feature is used to generate a BIP39 mnemonic phrase, which can be used to derive a wallet's private keys in a human-readable form.

const { generateMnemonic } = require('ethereum-cryptography/bip39');
const mnemonic = generateMnemonic();
