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.
