@ethersproject/hash

What is @ethersproject/hash?

@ethersproject/hash is a part of the ethers.js library, which provides utilities for hashing data. It includes functions for creating various cryptographic hashes, such as Keccak256, SHA256, and RIPEMD160, which are commonly used in Ethereum and other blockchain applications.

What are @ethersproject/hash's main functionalities?

Keccak256 Hashing

This feature allows you to create a Keccak256 hash of the given data. Keccak256 is a cryptographic hash function used extensively in Ethereum.

const { keccak256 } = require('@ethersproject/hash');
const data = '0x123456';
const hash = keccak256(data);
console.log(hash);

SHA256 Hashing

This feature allows you to create a SHA256 hash of the given data. SHA256 is a widely used cryptographic hash function.

const { sha256 } = require('@ethersproject/hash');
const data = '0x123456';
const hash = sha256(data);
console.log(hash);

RIPEMD160 Hashing

This feature allows you to create a RIPEMD160 hash of the given data. RIPEMD160 is another cryptographic hash function used in various blockchain applications.

const { ripemd160 } = require('@ethersproject/hash');
const data = '0x123456';
const hash = ripemd160(data);
console.log(hash);

Other packages similar to @ethersproject/hash

crypto-js

crypto-js is a widely-used library that provides a variety of cryptographic algorithms, including MD5, SHA1, SHA256, and more. It is more general-purpose compared to @ethersproject/hash, which is more focused on Ethereum-related hashing functions.

hash.js

hash.js is a library that provides a simple interface for creating various cryptographic hashes, including SHA256, SHA512, and RIPEMD160. It is similar to @ethersproject/hash but does not include Ethereum-specific optimizations.

js-sha3

js-sha3 is a library specifically for Keccak and SHA3 hashing functions. It is similar to @ethersproject/hash in terms of Keccak256 functionality but does not offer other types of hashes like SHA256 or RIPEMD160.
