Advanced tools
Package description
The @aws-crypto/sha256-js package is a JavaScript implementation of the SHA-256 hash function. It is part of the AWS SDK for JavaScript and is used to compute SHA-256 cryptographic hash values. This package is particularly useful when working with AWS services that require SHA-256 hashes, such as signing requests for AWS Signature Version 4.
Computing SHA-256 hash
This feature allows you to compute the SHA-256 hash of a given input. The code sample demonstrates how to create a new instance of the Sha256 class, update it with the data to be hashed, and then compute the digest.
const { Sha256 } = require('@aws-crypto/sha256-js');
async function computeHash(data) {
const hash = new Sha256();
hash.update(data);
return hash.digest();
}
computeHash('data to hash').then(console.log);Crypto-js is a popular package that provides cryptographic functions including SHA-256. It offers a wide range of cryptographic algorithms and is often used for encryption and hashing in JavaScript applications. Compared to @aws-crypto/sha256-js, crypto-js is more general-purpose and not AWS-specific.
js-sha256 is a simple SHA-256 hash function for JavaScript that supports UTF-8 encoding. It is lightweight and has no dependencies. Unlike @aws-crypto/sha256-js, it is not part of the AWS SDK and is designed for general use cases where SHA-256 hashing is needed.
hash.js is a JavaScript hash library that supports several hash functions including SHA-256. It is a pure JavaScript implementation and can be used in various environments. While @aws-crypto/sha256-js is focused on SHA-256 and AWS integration, hash.js provides a broader set of hash functions for different use cases.
