tweetnacl-js VS RbNaCl

This is great, finding NaCl (libsodium) has been a godsend, specifically the JS lib.

On cryptography, our whitepaper shares information on the general cryptography choices - login, authentication, keypairs, etc. It's quite similar to password managers or encrypted communication apps. In the actual product (code here https://github.com/skiff-org/skiff-mail), we use the library TweetNaCl (https://github.com/dchest/tweetnacl-js) which is designed to be fast, trustworthy, and performant

Working with encryption more broadly will equip you to understand the fundamentals that underpin the web3/crypto world: hashes, asymmetric crypto, signatures, signature chains, etc. And it also has many uses, of course, outside the web3 realm.

If you're working with Node, tweetnacl.js (https://github.com/dchest/tweetnacl-js) gives you secure defaults and a nice API to start learning and building with.

Once you're familiar with this stuff, blockchains/cryptocurrency/web3 loses a lot of its mystery. They're essentially all just different takes on using key management and signature chains to verify identities and

Those things are not the same. With the Berne Convention Implementation Act of 1988 (and the earlier Copyright Act of 1976, which went into effect in 1978), all works were by default copyright protected. In the absence of a legal notice, nobody can reliably use this for anything at all. Most jurisdictions don't even have a way of reliably dedicating anything to the public domain, hence the existence of permissive licenses. Please at least consider adding the ISC or MIT or Unlicense text or similar to a LICENSE or NOTICE file in your repository. An example: https://github.com/dchest/tweetnacl-js/blob/master/LICENSE

The other gem I want to explore is rbnacl. This gem provides general purpose cryptography for many different scenarios and algorithms. They do so in a simplified way so that mortals like us don't have to become cryptography experts. Check out these docs to see what I'm talking about!
