What is @smithy/hash-node?
@smithy/hash-node is an npm package designed to provide hashing utilities for Node.js applications. It is part of the Smithy framework, which is used for building SDKs and other tools. This package offers functionalities to create hash digests using various algorithms.
What are @smithy/hash-node's main functionalities?
Creating SHA-256 Hash
This feature allows you to create a SHA-256 hash of a given input string. The code sample demonstrates how to initialize a SHA-256 hash, update it with a string, and then get the hexadecimal digest of the hash.
const { Hash } = require('@smithy/hash-node');
const hash = new Hash('sha256');
hash.update('Hello, World!');
const digest = hash.digest('hex');
console.log(digest);
Creating MD5 Hash
This feature allows you to create an MD5 hash of a given input string. The code sample shows how to initialize an MD5 hash, update it with a string, and then get the hexadecimal digest of the hash.
const { Hash } = require('@smithy/hash-node');
const hash = new Hash('md5');
hash.update('Hello, World!');
const digest = hash.digest('hex');
console.log(digest);
Other packages similar to @smithy/hash-node
crypto
The 'crypto' module is a built-in Node.js module that provides cryptographic functionalities, including hashing. It supports various algorithms like SHA-256, MD5, and more. Compared to @smithy/hash-node, 'crypto' is more versatile and widely used but may not be as specialized for SDK development.
hash.js
The 'hash.js' package is a JavaScript library that provides hash functions for various algorithms like SHA-256, SHA-512, and more. It is similar to @smithy/hash-node in terms of functionality but is more focused on providing a wide range of hash algorithms.
bcrypt
The 'bcrypt' package is used for hashing passwords and is known for its security features. While it provides hashing functionalities, it is more specialized for password hashing and security, unlike @smithy/hash-node, which is more general-purpose.
