Create PDF files from Markdown sources in OSX

When [Markdown][markdown] appeared more than 10 years ago, it aimed to make it easier to express ideas in an easy-to-write plain text format. It offers a simple syntax that takes the writer focus away from the formatting, thus giving her time to focus on the actual content.

The market abunds of editors to be used for help with markdown. After a few attempts, I settled to Sublime and its browser preview plugin, which work great for me and have a small memory footprint to accomplish that. To pass the results around to other people, less technical, a markdown file and a bunch of images is not the best approach, so converting it to a more robust format like PDF seems like a much better choice.

[Pandoc][pandoc] is the swiss-army knife of converting documents between various formats. While being able to deal with heavy-weight formats like docx and epub, we will need it for the more lightweight markdown. To be able to generate PDF files, we need LaTeX. On OSX, the s

I'm working on cleaning up this advisory so that it's more informative at a glance. Suggestions are welcome.

This advisory addresses the underlying PHP vulnerabilities behind Dawid Golunski's [CVE-2016-10033][CVE-2016-10033], [CVE-2016-10045][CVE-2016-10045], and [CVE-2016-10074][CVE-2016-10074]. It assumes prior understanding of these vulnerabilities.

This advisory does not yet have associated CVE identifiers.

OpenPGP SSH access with Yubikey and GnuPG

NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

  • Simpler stack / less moving parts
  • Works directly with ssh, ssh-add and ssh-keygen on most computers
  • Simpler
  • Private key can never leave the FIDO device

Cons of FIDO
