Brainstorming session: what is key management really useful for? VPN.!?! Whatever is VPN for? Well, it could create a “private space”. A space where we could share documents, put private messaging server, or just make it a gateway to an existing office network or even the internet.

Transaction Security with Slow Clock and Counter – How to Conjure Up Entropy

I love cryptography. It’s an abstract science, where I can define a problem, come up with a solution and prove it (eventually). I also like applying cryptography as it involves real world (users, limitations of computers, …), which messes everything up and turns pure mathematics into a fun game.

Self-driving Cyber Security – Step 1: Professional PKI

Many companies drive their computer systems without wearing seatbelts, even though they know and constantly witness they risk being injured by cyber crashes. There are simple economic reasons for this. It is not the unavailability of cyber “seat belts”, but the difficulty of putting them in. Enigma Bridge technology gives customers self-driving cyber-security for safe navigation through the cyberspace and protection of its payload.

How Certbot and Letsencrypt Work (DNS and SNI-TLS automation)

We introduce an integration plugin for Let’s Encrypt. It provides integration for a variety of mechanisms that enable and simplify verification of domain control and certificate installation. We already tested it with Dehydrated (former letsencrypt.py) . It supports all existing verification methods: DNS, HTTP and TLS-SNI, in their current versions “01”.

Letsencrypt’s Vulnerability Or Feature – Eternal Account Key

 

The growth of Let’s Encrypt is phenomenal – 7 million certificates in last four months. The remaining hurdle for automation is verification of domain ownership. Well, actually it is NOT true. We were doing syntax testing – hoping to get the right kind of verification error … only to discover we have been successfully verified without providing any information.
