Without being able to directly answer that question: the encryption is byzantine trash, and they've never properly explained why they designed such a bizarre cryptosystem. Every time actual cryptographers ask (and several have), they just accuse them of being NSA stooges and defame them on twitter. According to the few attacks people have bothered to publish, Telegram have access to material that could let them break or spoof keys.
