Encrypting & Decrypting Sensitive Data With the Web Crypto API

Chris Veness created a really great gist that shares code to encrypt and decrypt data using the Web Crypto API here.

This gist breaks down the code in that gist step by step, detailing a real-world scenario with actual data.

It might be helpful to have that gist open in another tab and use this gist to walk through each line of code.

One interesting use case for this would be to encrypt on a client, and then decrypt in the cloud with something like a Lambda function. In order to do this, you could use Node's latest version as of this gist, version 15, which includes a webcrypto module that's designed to be a Node implementation of the Web Crypto API. Lambdas can't use v15 by default -- however, you can create a custom Lambda layer that contains v15.

Lazy/Dynamic Loadable Modules in PureScript

Motivation

https://discourse.purescript.org/t/lazy-loading-routes-in-tea-style-app/141/2

Ideas

• Here, we aren't first-class modules, because we are still using the normal module definition and import system. We believe that first-class modules refer to a special feature in OCaml.
• Can not refer to type classes across a lazy-load boundary. Type-class instances and classes are not first-class values.

List comprehensions

To see a working version of the code check out https://codesandbox.io/s/j497w26383 and open the console.

This file demonstrates a very basic List as an applicative functor for the purpose of demonstrating a simple list comprehension.

The idea for this was taken from: https://egghead.io/lessons/javascript-list-comprehensions-with-applicative-functors by https://twitter.com/drboolean

// Immutable Data Implementation
// Based on Hash Tries
// (NOTE: The actual implementation is based on hashed mapped tries!)
// But this can be seen as a basis for the actual implementation.
// This is only for learning purposes!

// Hash Trie or Hash Tree is a persistent data structure, commonly used
// to implement immuable maps.
