That is correct. It is used for encrypted email, but it does not mean
that is is used to secure classified discussions or transmit classified
documents. The CAC serves more as an identity card and authentication
token more than anything else in my experience. If the CAC card is used
to encrypt anthing beyond unclassified, for oficial use only, or
PII-sensitive (containing personally identifiable information) documents
and information is unknown to me. Even if it were, knowledge of the
fact would likely be restricted.
But do ask. I would like to hear what other people's experiences have
