HexaPDF - Digital signature via sign pad
To provide some context, I generate the signature image on the frontend using a sign pad (Wacom STU430) through the JavaScript library signature-sdk-js, also from Wacom. This library takes the PDF document from my Ruby backend as input and produces two output files: the PNG image of the signature and a specific ISO file. This ISO file, from what I understand, utilizing the PDF hash, ensures the secure linkage between the signature and the PDF.

Online Cryptography Course by Dan Boneh
This is great, finding NaCl (libsodium) has been a godsend, specifically the JS lib.

I am considering adding Skiff as an encrypted email provider and would like community feedback
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

Ask HN: Should I learn the tech behind crypto even if I don't want to own any?
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

A Hold'em Poker game in Clojure
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
