Not true. PKI certs/keys are tied to the person.
“With the possible exception of One Time Pads, keying material is not tied directly to an individual.”
While they are fine for most personal and business uses they are too weak for government use.
One of the things that frustrated the Soviets in the 50s & 60s was that we encrypted almost everything at the Top Secret collateral level. They then had to figure out which transmission was really secret and which was a supply request for more toilet paper or a leave request for seaman Schmedlap.
This is one reason why bulk encryption of data (emails, etc) is so important and why Hillary's non-use of a government system is so damning.

I think they did the work of tie in with the invention and use of the CAC card. They made it the only way to get into the system at any level. I carried one for about four years of the 26 I had access to a government computer. (I retired in 2012.) And just to get in, it required a SAAR report.
The real problem I see is not the aspect of her receiving and sending sensitive material at all levels to be hacked, even though this is a problem, but the report that she was instructing her subordinates in how to use patch and paste to bypass the security system, probably with the removal of the level codes. And as this was done on a “private server” it is more than possible she had no CAC requirement at all. This they re not saying. So this is not a matter of a mistake. This is an intentional effort to bypass the system making it espionage. And by trying to do it to her government, it is treason.
And that is a whole different story than a mistake.
