Route SSH connections through HAProxy using the SSH ProxyCommand feature and SNI.

Russian-funded English-language website aimed at sowing divisions among Americans has had a vital internet security certificate yanked, meaning U.S. internet users will have difficulty accessing the site.

Those that know me or have followed me online will know I'm a massive advocate of encryption on the web. One of my goals is to help encrypt as much of the web as I can by sharing knowledge and information, building tools and services, speaking at conferences and countless other things. I see this blog post as part of that mission.

First, I find amusing that many people like to quote "if that is free, then you are the product", but when it comes to Let's Encrypt, they forget this statement and enjoy their certificates carelessly.

Google has warned that all certificates issued by Chinese company WoSign and subsidiary StartCom will be distrusted with the release of Chrome 61.

Let’s Encrypt will begin issuing wildcard certificates in January of 2018. Wildcard certificates are a commonly requested feature and we understand that there are some use cases where they make HTTPS deployment easier. Our hope is that offering wildcards will help to accelerate the Web’s progress towards 100% HTTPS.

I've written quite a few blogs on how to get started with Let's Encrypt and covered both RSA and ECDSA certificates. In this blog I'm going to look at how we revoke them.

C'est la controverse de la semaine, lancée par un billet de SSL Store, autorité qui délivre des certificats SSL payants.

This code was introduced in OpenSSL 1.1.0d, which was released a couple of days ago. This is in the server SSL code, ssl/statem/statem_srvr.c, ssl_bytes_to_cipher_list()), and can easily be reached remotely. Can you spot the vulnerability? (read ahead for the answer)

All systems behind a hypertext transfer protocol secure (HTTPS) interception product are potentially affected.

L’offre de certificats gratuits proposée par Let’s Encrypt est généralement vue comme une aubaine qui a permis aux administrateurs de site web de facilement adopter le chiffrement HTTPS sur leurs sites. Mais ces certificats sont également utilisés par des cybercriminels qui souhaitent légitimer leurs sites contrefaits.

Nick Sullivan and I gave a talk about TLS 1.3 at 33c3, the latest Chaos Communication Congress. The congress, attended by more that 13,000 hackers in Hamburg, has been one of the hallmark events of the security community for more than 30 years.

LetsEncypt est une autorité de certification utilisant une API basée sur des appels HTTP et un client côté serveur qui va générer des tokens lus par les serveurs LetsEncrypt.

Nous allons ici voir une architecture LetsEncrypt typique dans laquelle nous allons utiliser le client acme-client d’OpenBSD disponible dans les ports et les packages FreeBSD.

Rich Salz and Tim Hudson started off their LinuxCon Europe 2016 talk by stating that April 3, 2014 shall forever be known as the "re-key the Internet date." That, of course, was the day that the Heartbleed vulnerability in the OpenSSL library was disclosed. A lot has happened with OpenSSL since that day, to the point that, Salz said, this should be the last talk he gives that ever mentions that particular vulnerability. In the last two years, the project has recovered from Heartbleed and is now more vital than ever before.

J’ai moi aussi sauté le pas vers let’s encrypt avec toute l’encre numérique qu’il a fait couler ces dernières semaines j’ai eu envie d’en voir un peu plus. Cela tombe bien je projetais depuis un moment de chiffrer le blog alors « endavant ! » comme on dit par chez moi.

This application is intended for creating and managing X.509 certificates, certificate requests, RSA, DSA and EC private keys, Smartcards and CRLs. Everything that is needed for a CA is implemented. All CAs can sign sub-CAs recursively. These certificate chains are shown clearly. For an easy company-wide use there are customiseable templates that can be used for certificate or request generation. All crypto data is stored in an endian-agnostic file format portable across operating systems.

Les autorités de certification racine… Comment pourrait-on ne pas en parler quand on parle de TLS ou de HTTPS…
