I wonder why they used an assymetric algo.

Maybe for performance so as to decrease the chances of detection

Edit: sorry disregard my comment, I read that as “symmetric”. In the case of asymmetric they can only deploy one part of the key which if intercepted cannot be used to decrypt.

Yeah that makes sense, I figured they’d just spin up a symmetric key, use it, send it home and delete it locally.

Can someone elaborate? I’m not as informed…

Check my comment to flyswat.

Why would they use a symmetric algorithm?

Valmond@lemmy.world on 18 Mar 2025 09:23 collapse

Uncrackable.

I mean big assymetrics are too, but it’s more complicated to use and much slower.
