TweetNaCl.js: Cryptographic Library

TweetNaCl.js is a JavaScript port of the TweetNaCl/NaCl cryptographic library, designed for modern browsers and Node.js. It provides a thin layer of idiomatic high-level API over a faithful translation of the original C implementation, prioritizing security and correctness. The library ships with two versions: `nacl.js` (a direct port) and `nacl-fast.js` (which includes faster, optimized functions and is used by default when installed via npm). Currently at version 1.0.3, it maintains a stable release cadence with updates typically addressing security fixes or minor improvements. A key differentiator is its public domain license and a comprehensive audit by Cure53 in 2017, which found no security problems, cementing its reputation as a robust and secure cryptographic tool. All API functions operate on `Uint8Array` for byte handling.
