"What the heck is a Yubikey and why did I buy one?": A user guide

(EDIT: Besides Reddit, I've also put this up on Github Gist)

So while looking for information on security keys before getting one myself, I got very confused reading about all the different modes and advertised features of Yubikeys and other similar dongles. The official documentation tends to be surprisingly convoluted at times, weirdly organized and oddly shy about a few of the limitations of these keys (which I'm making a point of putting front and center). Now that I have one, I decided to write down everything I figured out in order to help myself (and hopefully some other people reading this) make sense of all this.

Since I'm partly writing these notes for myself, there might be some back and forth between "exp

Renew GPG key

Given that your key has expired.

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

Copy Trello Board as text or markdown

Wouldn't it be nice to copy out your Trello board as plain text or markdown to be able to put it in a weekly memo, shipping notice or release notes? Now you can!

How to use this

Copy this line of JS and paste it into the CONSOLE in your browser. The results will be saved to your clipboard.

Option 1: Copy your Trello Board as Markdown

This will copy your columns + cards as markdown right to left

var s = []; s.push("# " + jQuery(".board-header").children()[0].innerText); jQuery.fn.reverse = [].reverse; jQuery(".list:has(.list-header-name)").reverse().each(function() {s.push("\n## " + jQuery(this).find(".list-header-name-assist")[0].innerText + "\n"); jQuery(this).find(".list-card-title").each(function() {s.push("* " + this.innerText); }); }); copy(s.join("\n"));

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from
