RFC3709, "Internet X.509 Public Key Infrastructure: Logotypes in X.509 Certificates", February 2004

Source of RFC: pkix (sec)

Errata ID: 2679

Status: Held for Document Update
Type: Technical

Reported By: Alexey Melnikov

Section 4.1 says:

LogotypeDetails ::= SEQUENCE {
   mediaType       IA5String, -- MIME media type name and optional
                              -- parameters
   logotypeHash    SEQUENCE SIZE (1..MAX) OF HashAlgAndValue,
   logotypeURI     SEQUENCE SIZE (1..MAX) OF IA5String }

Notes:

The mediaType is underspecified, as no specific syntax is given.
E.g. are spaces allowed before parameters? Also, my understanding is that IA5String disallows UTF-8, while media type parameters can possibly include UTF-8 values.

I would recommend referencing ABNF from Section 4.2 of RFC 4288.

Section 4.1 says:

   When using indirect addressing, the URI (refStructURI) pointing to
   the external data structure MUST point to a binary file containing
   the DER encoded data with the syntax LogotypeData.  The referenced
   file name SHOULD include a file extension of "LTD".

Notes:

There is no IETF process for only registering a file extension. IETF MIME type registry allows to register MIME types together with the corresponding file extensions. An update to this document should register a new MIME type for "LTD".
