Note to myself: How to disable OTR in ChatSecure



Some weeks ago, a colleague, who unfortunately uses an iPhone (he is not a completely bad person, though) installed ChatSecure. Immediately, I and others were annoyed by unreadable OTR garbage he sent. It took us a while, but at the end of the day (the whole day!) we found out how to disable OTR. Yesterday, a friend who unfortunately also uses an iPhone (he is not a completely bad person neither), had the same issue and it took me the help of strangers on the internet (here; the Conversations MUC), to remember what to do. For the next time and the benefit of the public:
  • One cannot disable OTR globally in ChatSecure, but only contact by contact.
  • You need to open the chat of the contact.
  • Go to the "contact details".
  • Go to "advanced encryption settings" and select "OMEMO", nothing else.
  • Close chat with the contact.
  • Repeat the last four steps for all your 511 contacts.

Welche Messenger unterstützen schon OMEMO?



#messenger #it-sicherheit #xmpp #omemo #olm #xep0384

OMEMO ist seit Dezember 2016 offiziell XEP-0384 und seit Kurzem für ChatSecure verfügbar.

Wer wissen will, wie es mit anderen Messengern aussieht, kann einen Blick auf die Übersicht „Are we OMEMO yet?“ werfen.

YAXT: Yet another XMPP tutorial


Well, this is going to be another tutorial, but I'm going to try to make it a little bit different. This is an XMPP tutorial from an iOS developer's perspective.

While iOS is not my cup of tea, I find this tutorial interesting and well-written. Worth a read for everyone curious about XMPP!

Sander Venema: Why I won’t recommend Signal anymore


One of the things I do is cryptography and infosec training for investigative journalists who have a need to keep either their sources and communications confidential so they can more safely do their work in the public interest. Often they work in places which are heavily surveilled, like Europe, or the United States. Ed Snowden’s documents explain a thing or two about how the US intelligence apparatus goes about its day-to-day business. They sometimes also work in places in the world where rubber hose cryptanalysis is more common than in say the U.S. or Europe. Which is why crypto tools alone are not the Alpha and the Omega of (personal) security. This requires careful consideration of what to use when, and in what situation. One of the things I have recommended in the past for various cases is the OpenWhisperSystems’ app called Signal, available for Android and iOS. In this article, I want to explain my reasons why I won’t be recommending Signal in the future.
To be clear: the reason for this is not security. To the best of my knowledge, the Signal protocol is cryptographically sound, and your communications should still be secure. The reason has much more to do with the way the project is run, the focus and certain dependencies of the official (Android) Signal app, as well as the future of the Internet, and what future we would like to build and live in. This post was mostly sparked by Signal’s Giphy experiment, which shows a direction for the project that I wouldn’t have taken. There are other, bigger issues which deserve our attention.
