I sent the President [JFK] a telegram marked SECRET to be sure that it had wide distribution.
In America they started to refer to Telegram as 'ISIS's preferred messaging app,' But in reality there are many more legitimate users.
At WhatsApp, our engineers spend all their time fixing bugs, adding new features and ironing out all the little intricacies in our task of bringing rich, affordable, reliable messaging to every phone in the world. That's our product, and that's our passion. Your data isn't even in the picture. We are simply not interested in any of it.
One thing Telegram does is make mass surveillance impossible.
Our focus remains on delivering the promise of WhatsApp far and wide so that people around the world have the freedom to speak their mind without fear.
We need to make sure that organisations like WhatsApp - and there are plenty of others like that - don't provide a secret place for terrorists to communicate with each other.
Texting is a supremely secretive medium of communication - it's like passing a note - and this means we should be very careful what we use it for.
The No. 1 reason for me to support and help launch Telegram was to build a means of communication that can't be accessed by the Russian security agencies, so I can talk about it for hours.
Terrorists will always find a way to communicate. They will always find a solution.
The terrorists that we are up against today do not rely upon cell phones and SAT phones and emails. They rely on couriers. You cannot intercept what a courier is telling somebody.
One advantage that I think Slack has for most people who use it is, you pull out your phone, you look at the home screen, there's the Slack icon. You know when you tap this one, it's all the people you work with, and it's only the people you work with. And that's a big advantage.
I am sending this message to you by wire, since I want to be certain that this message reaches you in the right place at the right time.
The President was unable to attend a testimonial luncheon for his postmaster general and wired his regrets:
I trust and use RakEM for my private messages and calls. Other messengers collected metadata about who I messaged, when and where - RakEM does not collect metadata, encrypts local files, and uses the strongest end-to-end encryption around.
We think that providing this kind of secure private means of communication for the masses for 99.999 percent of people that have nothing to do with terrorism means more than the threat that we see from the other side.
I realized I don't have a safe means of communications. That's how Telegram started.
In this age of communications that span both distance and time, the only tool we have that approximates a 'whisper' is encryption. When I cannot whisper in my wife's ear or the ears of my business partners, and have to communicate electronically, then encryption is our tool to keep our secrets secret.
If you send emails to your spouse or your lawyer or family members, you want to have these messages be confidential.
The first rule in keeping secrets is nothing on paper: paper can be lost or stolen or simply inherited by the wrong people; if you really want to keep something secret, don't write it down.
