I can successfully verify the signatures on all these now (except for
Diane's sig on 5.6, as we don't support parameter inheritance).

Ok, I can successfully decrypt all these now, except for 6.7 which I
haven't tested yet.

Note that 6.4, 6.5, and 6.8 all still have the wrong OId in the
KeyEncryptionAlgorithmIdentifier.

Umm, this is getting confusing. For one, the key and certificate you
just provided are identical to those in the examples-06 document. The
correct key however can be found in
http://www.imc.org/ietf-smime-examples/mail-archive/bin00002.bin .
Using this I can decrypt 6.2, 6.3, and 6.9.

OTOH, I can't verify Bob's signature 11.2 - was that perchance
generated using the key from examples-06?
