@ethersproject/sha2
Advanced tools
Package description
@ethersproject/sha2 is a part of the ethers.js library, which provides utilities for interacting with the Ethereum blockchain. This specific package focuses on SHA-2 hashing algorithms, allowing developers to create secure hashes for data integrity and cryptographic purposes.
SHA-256 Hashing
This feature allows you to create a SHA-256 hash of a given input. SHA-256 is a widely used cryptographic hash function that produces a 256-bit hash value.
const { sha256 } = require('@ethersproject/sha2');
const data = 'Hello, world!';
const hash = sha256(data);
console.log(hash);SHA-512 Hashing
This feature allows you to create a SHA-512 hash of a given input. SHA-512 is another cryptographic hash function that produces a 512-bit hash value, offering a higher level of security compared to SHA-256.
const { sha512 } = require('@ethersproject/sha2');
const data = 'Hello, world!';
const hash = sha512(data);
console.log(hash);The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including a variety of hash functions like SHA-256 and SHA-512. It is more versatile and widely used but may not be as specialized for Ethereum-related tasks as @ethersproject/sha2.
The 'js-sha256' package is a lightweight library for SHA-256 hashing in JavaScript. It is highly optimized for performance and can be used in both Node.js and browser environments. However, it does not support SHA-512 hashing.
The 'sha.js' package is a simple library for SHA family hashing algorithms, including SHA-256 and SHA-512. It is similar in functionality to @ethersproject/sha2 but is not specifically tailored for Ethereum development.
