PAVEL DUROV REVEALS BROTHER NIKOLAI DESIGNED TELEGRAM’S ENCRYPTION SYSTEM
Pavel Durov:
"My brother has, like, two PhDs in maths, super smart.
He is an expert in cryptography. He designed the basic principles of Telegram’s encryption.
I was more on the user interface side, the way how the app works, the features, etcetera.
He was responsible for it, for the encryption side."
