@benjojo it was enough that it makes the difference between my laptop fans running or not. https://flak.tedunangst.com/post/why-did-my-fans-come-on

@benjojo doesn't seem like much compared to LLMs or cryptocurrencies.

@benjojo 500 successful ssh connections with RSA key exchange takes 33s against a Pi4, which is ~200J (~6-7W) which gives you 0.4J for each completed connection. This is an upper bound as it includes the entire power consumption for the machine (3W at idle). My laptop estimates a 2W marginal increase in consumption during the test so intel/arm is similar efficiency. Complete connection setup/teardown is therefore around ~ 0.1-0.2J at each end.

hey @benjojo we've figured out how to nerdsnipe @beasts , this information can be weaponised.

@_aD @benjojo only *one* of the ways!

@benjojo enforce ed25519, it becomes cheaper ;)

@leah @benjojo All of a sudden I'm wondering how many bulk attackers would go away if we only offered ed25519 host keys.

@cks @benjojo only one way to find out :)

@cks @leah @benjojo I actually do this and it's more effective than one would think

disabling http/1.0 goes that way too
