@matthew_d_green ah, so the @signalapp secure contact enclave is weakened?
@matthew_d_green I don’t see it as “less security”
It’s more that they handle one attack vector very well and another vector very badly.
It’s then becomes a discussion about threat models.
If people have physical access to the server then all bets are off, but that’s not top of the threat model for most people.
@matthew_d_green deterministic encryption strikes again!
