I have wanted this for a long time. there are actually three separate
problems to be solved.
1) How to make S/MIME work with OpenPGP credentials
2) How to make OpenPGP work with S/MIME credentials
3) How to merge the two specifications into one.
The first two are pretty easy, I've been doing that for years. For S/MIME,
use the subjectKeyIdentifier form of the key ID. For PGP, use an
issuerAndSerialNumber in a type-and-value subpacket.
The third is impossible. While at an abstract level PGP and S/MIME do the
same thing, the bit-bagging formats used to encode the abstraction are
completely incompatible. You can't make them compatible without either
moving
S/MIME to the PGP format or PGP to the S/MIME format. I can't see either
of
those happening...
That would clearly be impossible if it was what was being proposed.
What I am suggesting is rather different, A new application for managing
encrypted content, Word, Powerpoint, PDF, etc. that has crypto designed
into the metal and also provides a messaging capability.
I am suggesting Blu Ray, not trying to develop adapters to play VHS on
Betamax.
