comment Is Telegram secure?
Also, dismissing the entire post because of one angry comment is a bit dishonest: this is also an emotional response, and not making a decision on facts. I corrected the errors in good faith, while they avoided a lot of my questions. Adding to that the frustration of reading a weirdly design protocol, and their attitude, yes, I got angry, I'm only human :) If there's a good reason to avoid that post now, it would be because it is 2 years old, so it may not reflect Telegram's current protocol.

comment Is Telegram secure?
Hi, I'm the author of the "Unahandlede expression" blog. Since I still get traffic from this page even 2 years after writing that post, I'd like to correct a few things: WhatsApp uses the Axolotl protocol, an improvement on OTR developed by WhisperSystems. They helped Whatsapp in implementing it, so it is closed source, yet reviewed. If you still don't trust closed source, see the open source Python Whatsapp lib, using Axolotl

comment How do you Secure VOIP in a large organization
There is a lot of research around using IBE (identity based encryption) to simplify key management in VoIP. It would be a good idea to investigate these solutions.
