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

Generate MD5 Hash

This feature allows you to generate an MD5 hash from a given input string. The code sample demonstrates how to create an MD5 hash of the string 'Hello, world!' and print it in hexadecimal format.

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

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

Update Hash with Multiple Chunks

This feature allows you to update the MD5 hash with multiple chunks of data. The code sample demonstrates how to update the hash with two separate strings and then generate the final hash.

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

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

Asynchronous Hashing

This feature allows you to perform MD5 hashing asynchronously. The code sample demonstrates how to generate an MD5 hash of the string 'Hello, world!' using a promise-based approach.

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

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