  I wonder why they used an assymetric algo.

    Maybe for performance so as to decrease the chances of detection

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

    Why would they use a symmetric algorithm?

      Uncrackable.

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