I'd challenge that. The largest, and probably disproportionately most
expensive PKI system in Ireland is operated by the Revenue
Commissioners allowing the general public deal with them
electronically.

They issue you with a digital cert and private key in PKCS12 format
from their CA for you to sign all online dealing with them in a non
repudable fashion.

Sing up at www.ros.ie and try and change the password for that PKCS12
file outside of the ROS system. Can't be done with any PKCS12 tool
available.

Similar devices are at the disposal of all CA operators....

Aine.
