That's INSANE
Like, that had to be malicious right? ssh-keygen won't generate a key like this, and neither will openssl or whatever Microsoft is doing behind their CA server.
Maybe it was just a mistake and they intended to generate a `--bitsize 4` thinking it was in kilobyte units.
shrug
I think they're just absolutely inept and should never be trusted with anything security related as an organisation if this is a mistake they could make.
It's 0x0000000000000000000....4, but no, just good ol' human failure (and a bunch of extra f-ups along the way)
