With quantum getting more feasible, I’d imagine it’s almost without question that some parts of the government can use that to break AES. To me the question is really one of throughput — if they can only break, say, one a day, they won’t bother doing that for a small potatoes Signal convo between people planning a protest, or something.
If it’s more like 100 million a day, though, It’s definitely time to start getting more worried...
Well AES is actually believed to be quantum resistant for any reasonable attack (however we have no proof). RSA and other factoring based key exchanges are not secure, however we already have quantum resistant lattice algorithms ready to go. IMO breaking a single in use Diffie Helman key exchange algorithm with a quantum computer is still at least 6-10+ years away.
