"A mere three days after Mark Zuckerberg announced Facebook's acquisition of Whatsapp, the popular smartphone messaging app suffered a major service outage that lasted three and a half hours. Left to their own devices, Whatsapp users worldwide went rushing to its rival apps, including secure chat provider Telegram. The surge in new users quickly turned into a tidal wave that brought Telegram's service to its knees:
The SMS gateways we use to send registration codes are overloaded and slow 100 SMS per second is too much. Trying to find a solution.
In its official twitter, Telegram announced that more than 1.8 million new users had joined on Saturday, Feb 22. Four hours later, it reported an additional 800 thousand.
Telegram's messaging service, which uses 256-bit symmetric AES encryption, RSA 2048 encryption and Diffie-Hellman secure key exchange, began enjoying a spike in popularity after Whatsapp's acquisition. Although it has released the source code for its java libraries and all its official clients, its server software is still closed source."

According to your friendly neighbor Wikipedia, the Diffie-Hellman key exchange method [wikipedia.org] "allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure communications channel".

But if you can trust your software clients the picture stuff does give some sort of plausibility if you verify them over a different channel (or you directly verify the keys over that channel).
