Bill:
I should think that a signer would not apply a countersignature without
verifying the signature that it covers. One important place that
countersignature might be used is a workflow application where concurrance
is needed.

Hi all,
I would like to know whether anyone uses or intends to use the
Countersignature attribute type defined in section 11.4 in
draft-ietf-smime-cms-04.txt.
I myself do not see a use for it as I can't trust it. It is not
authenticated and it provides one or more signatures on a signature value
which may not be valid.
Bill.
