An added E-Mail Issue

Hi,

I forgot to add an important issue that can be addressed by the
e-mail<=>PGP Key lookup list.

With PGP 5.0's ability to uses multiple encryption/hash algortihms the
need has arose to be able to set the default algortihms to be used by an
application for a given e-mail address. This can be accomplished by adding
an extra field in the lookup list.

Things like:

  -- Owner of address is using 2.6.x therfore RSA/MD5 signatures should
only be used.

  -- Owner of address is using 5.0 but would prefer that RSA/MD5 be used.

  -- Owner of address has 5.0 but would prefer that RSA/SHA1 be used.

... and so on and so forth.

In the settings either for PGP or the application there should be some
type of option of a general default algortihm to use when presented with
multiple choices:

  - Owner of address has both DSS & RSA keys but their preferances are
unknown. In such a senario it is up to the user to determine which
combination of algorithms should be used (Public key, Session key,
Private/Signature key, and Hash). This may vary between the different
applications that PGP is being used with for a variety of reasons.
