Hash.js serves as an efficient JavaScript library that incorporates various hash functions executable in both web browsers and node.js. Being extensively employed in cryptography, hash functions are paramount for generating a fixed-size text string from any given data input. This is beneficial for the secure storage of passwords, digital data comparisons, data retrieval, and building hash tables, to name a few applications.
In order to utilize the functionalities provided by hash.js, begin by installing the package through npm (Node Package Manager) using the command: npm install hash.js. Once installed, it can easily be included and used in a JavaScript file like so:
var hash = require('hash.js');
hash.sha256().update('abc').digest('hex');
The above code will generate a SHA-256 hash of the string 'abc' and output it in hexadecimal format.
If you wish to use a specific hashing function from the library, you can selectively import and use it as follows:
var sha512 = require('hash.js/lib/hash/sha/512');
sha512().update('abc').digest('hex');
This snippet generates a SHA-512 hash of the string 'abc' and ouputs it in hexadecimal format.
The documentation for hash.js can be found on the GitHub repository. As of now, the README document present there serves as the primary source of documentation and usage instructions for this package.
