Needed for its AES-256 cipher, which is used to build the AES-IGE mode used by Telegram.
Used to generate secure padding when encrypting outgoing messages.
Used for hand-rolled RSA encryption, which is used during the generation of an authorization key.
This may make the second part of the authorization key vulnerable to a certain type of timing attack, although I'm not sure how dangerous it is in practice.
If this concerns you, please propose a fix and send a pull request.
Used in certain functions that require a certain AES key.
Used for calculating the AES key given an authorization key, and also for 2FA.
Used for methods relied on by the 2-factor offered by Telegram.
