tweetnacl 0.14.5

TweetNaCl is a port of the TweetNaCl cryptographic library to JavaScript intended for modern browsers and Node.js. Its primary purpose is to offer an idiomatic high-level API on top of TweetNaCl while keeping the translation as close as possible to the original C implementation. As the package name suggests, it focuses on encryption and decryption, providing API functions for public-key authenticated encryption, secret-key authenticated encryption, scalar multiplication, signatures, hashing and random bytes generation.

Using TweetNaCl involves importing it into your project and then calling its functions as needed. For instance, after installing TweetNaCl via npm or yarn, you might use it in a Node.js script like this:

var nacl = require('tweetnacl');
nacl.randomBytes(10);

The above code imports the 'tweetnacl' module and uses it to generate an Uint8Array with 10 random byte values. In the browser, the package exposes itself as a global object named 'nacl'. Here's a sample usage:

var pair = nacl.box.keyPair();
console.log(pair.publicKey, pair.secretKey);

This script creates a new public and secret key pair for box encryption and logs them to the console.

Keep in mind that to leverage TweetNaCl fully, you must familiarize yourself with a variety of methods it offers like 'nacl.box', 'nacl.box.keyPair', 'nacl.box.open', 'nacl.secretbox', 'nacl.secretbox.open' and 'nacl.hash', among others.

For complete documentation of TweetNaCl, see the README in its GitHub repository. This document provides detailed explanations of all the library's functions, along with examples of how to call them. For more hands-on learning, you can check out the usage examples in the package's wiki. Remember that understanding how to use TweetNaCl effectively requires a basic understanding of cryptographic concepts and the specific algorithms it implements.
