@aws-sdk/md5-js

What is @aws-sdk/md5-js?

@aws-sdk/md5-js is a JavaScript library provided by AWS that allows you to compute MD5 hashes. It is part of the AWS SDK for JavaScript and is typically used for generating checksums for data integrity verification.

What are @aws-sdk/md5-js's main functionalities?

Compute MD5 Hash

This feature allows you to compute the MD5 hash of a given input string. The code sample demonstrates how to create an instance of the Md5 class, update it with a string, and then compute the hash synchronously.

const { Md5 } = require('@aws-sdk/md5-js');

const md5 = new Md5();
md5.update('Hello, world!');
const hash = md5.digestSync();
console.log(Buffer.from(hash).toString('hex'));

Compute MD5 Hash Asynchronously

This feature allows you to compute the MD5 hash of a given input string asynchronously. The code sample demonstrates how to create an instance of the Md5 class, update it with a string, and then compute the hash using a promise.

const { Md5 } = require('@aws-sdk/md5-js');

const md5 = new Md5();
md5.update('Hello, world!');
md5.digest().then(hash => {
  console.log(Buffer.from(hash).toString('hex'));
});

Other packages similar to @aws-sdk/md5-js

crypto

The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including the ability to compute MD5 hashes. It is more versatile and widely used compared to @aws-sdk/md5-js, as it supports a variety of cryptographic algorithms and is part of the Node.js standard library.

md5

The 'md5' package is a popular npm package for computing MD5 hashes. It is lightweight and easy to use, making it a good alternative to @aws-sdk/md5-js for simple MD5 hashing needs. However, it does not offer the same level of integration with AWS services.

hash.js

The 'hash.js' package is a JavaScript library that provides a variety of hash functions, including MD5. It is more comprehensive than @aws-sdk/md5-js, offering multiple hashing algorithms and a consistent API for all of them. It is suitable for applications that require more than just MD5 hashing.
