PKCS Mime Types

[Rick Beton <ri...@dsl.pipex.com>]

Hi Guys n Gals,

I'm new to this list. Forgive me therefore if I seem to barge in! :-)

I was wondering about the mime.types configuration file. There are what 
appear to me to be a couple of omissions thus:

application/x-pkcs7-certificates     p7b
application/x-x509-email-cert        pem, cer


because these extensions and Mime Types do seem to be in use. Microsoft 
for example, use the .cer extension.

Regards,
Rick

Eh - IANA (see RFC 2048) does not saction extension; all what is
really required/registered are MIME type name and MIME subtype name.
Extensions are just a nice option.

A more correct (in my option) reason for not including the above is that
they start with an 'x-'; i.e. experimental/placeholder.

   Proposed media types are not formally registered and
   must not be used; the "x-" prefix specified in RFC 2045 can
   be used until registration is complete.

Mimetypes which -are- registered are

application/
	pkcs7-mime                                  [RFC2311]
	pkcs7-signature                             [RFC2311]
	pkcs10                                      [RFC2311]

which *suggests* the extensions .p7m/p7c, .p7s and .p10 respectively.

None is registered for x509.

Would it help to have the above official ones registered ? Or would that
just confuse things ?

hi Rick
The only extensions which can go in the mime.types are IANA sanctioned ones.
