hey gentleman, would you like to share your wisdom? we want to implement encryption in our app too, and we are not knowledgeable enough, ofcourse you don't have to share your wisdom for nothing.

It is unclear how F gets its private key at 6'16''. It is also unclear why the rachet can go up the tree as well as down the tree.

It’s a bit confusing in the graphics but F must derive its own Public Private key pairs itself first, give Alice the public key, then Alice will wrap the group secrets (tree private keys) with Franks public key so that F can join the group chat. F gets its welcome message directly from Alice. Basically you can use any method to give F the welcome message.

Also think of the ratchet as the “propagation path” for a new key. The ratchet doesn’t HAVE to go unidirectional on the tree. The ratchet is in the direction of any new key that’s being propagated.

HELP

Epic? Quit saying epic. Its clearly the other pronunciation. Because your way of doing it is ambiguous with another word.

I've never heard it aloud that way. How bizarre. I wouldn't have thought it was a controversial word

Ikr. If pronouncing it as epic is ambigous, why not save us the confusion?
