String += String

Im in a 200 level java class. We're just learning inheritance. I could have told you why thats a bad way to do things.

Do people not study what arrays are and why its expensive to continually append to them anymore?

Maybe these folks need to go back to basics.

And you've provided no evidence or analysis why you're supposed mitigations are an insurmountable defense; at best they're only a stop-gap.

In THEORY breaking most encryption is just guessing the right 2048-bit code. At best, increasing the length from 1024 to 2048 is just a stopgap.

In reality, some attacks are so esoteric and hard to pull off (famous example: hard drive magnetic domain remnant detection) that they are not a real-world threat. MAYBE they could adapt this, but it already requires
A) a machine connected to the internet that is compromised (!)
B) an AIR-GAPPED, high-security machine directly adjacent to it (!!!)
C) That that air-gapped machine be compromised as well (!!!!!)
D) Sensors in both machines sensitive enough to detect incredibly minor fluctuations in temperature (given that a steady stream of air will be flowing through)

The proper security procedure is to analyze the chance of the risk, the annualized loss expectancy, etc, and then come up with mitigations. Ok, let me give this a shot.
1) DONT GET YOUR AIRGAPPED MACHINE INFECTED
2) probably dont stick it directly adjacent to non-airgapped machines
