  • Matthew Green on Telegrams Encryption

    Hello Jay!

    From https://telegram.org/faq#secret-chats

    "Newer versions of Telegram apps will show a larger
    picture along with a textual representation of the key
    (this is not the key itself, of course!) when both
    participants are using an updated app."

    At least they acknowledge there are issues with the current
    representation. Meaning.. there maybe a significant number of
    users who provided feedback to influence a change.


    Looks like it might be a fingerprint of the actual key.

    Yes.. that's a better way of describing that part.

    Below the picture and sequence of hex numbers it says:
    "This image and text were derived from the encryption
    key..." So it's clear it's not the key itself!

    Yeah.. I glossed over the accompanying text and derived a
    stupid question. :( In restrospect it would seem dumb to
    expose an actual key like that. Perhaps it would have been
    better to call it "special comparison sequence". Jay's comment
    about calling it a fingerprint is good.
