JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

Cheatsheet: pyenv, virtualenvwrapper, and pip

Installation (for Mac OS)

Install pyenv with brew

brew update
brew install pyenv

Server-Sent Events Demo

Server-Sent events is a specification for implementing server-side-push for web frontend applications, through plain-old HTTP.

It is best contrasted with WebSockets, which offer a full-duplex messaging channel over a custom protocol, operating within a single TCP connection (with an HTTP-compatible handshake).

Trying out the demo

Ruby to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in Ruby and Rust so that programmers most comfortable with Ruby can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?
