As part of the SDES integration in Jitsi, I need to modify the SecurityPanel in the call window. In contrast to ZRTP, there's nothing to validate or check for the user when SDES is being used. (And as soon as MIKEY comes into play again, there should be yet another panel that shows the peer's certificate).
So my idea is to make the existing SecurityPanel abstract and create a specific implementation for each supported encryption.
Along that, I want to remove the OperationSetSecureTelephony: setSasVerified is ZRTP specific, isSecure is never used. Everything needed to set the SAS verification can be placed in the CallPeerSecurityOnEvent (also to be made abstract and create security-procotol specific derived classes).
