vCard S/MIME Capabilities Property
draft-turner-vcard-smimecaps-00.txt
Abstract
This document defines a vCard S/MIME Capabilities property and it
defines or references values for many algorithms. The SMIME
Capability values can also be included in S/MIME messages as a signed
attribute and in public key certificates as an extension. The S/MIME
Capabilities property is a complement to key property, which together
enable usage of S/MIME without an initial exchange of email messages.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."

1. Introduction
This document defines or references values for the vCard S/MIME
Capabilities property. The syntax for the property is defined in
[RFC5751], but the values for each capability instance are defined in
separate RFCs and in some cases not at all. Capability values can
also be included in S/MIME messages as an attribute and in public key
certificates as an extension [RFC4262].
The majority of the values in this document are defined in other
RFCs, and this document references those RFCs before the SMIME
Capability. Values are encoded using the Distinguished Encoding Rule
(DER) [X.690] and are a sequence of algorithm object identifier plus
any parameters. The values provided in this document are values for
single SMIMECapability instance, which contain one algorithm-
parameter pair. These values may be concatenated and preceded by a
tag and length value to produce a SMIMECapabilities value. The
syntax for the attribute is as follows and is repeated here from
[RFC5751] for convenience:
SMIMECapabilities ::= SEQUENCE OF SMIMECapability
SMIMECapability ::= SEQUENCE {
capabilityID OBJECT IDENTIFIER,
parameters ANY DEFINED BY capabilityID OPTIONAL }
As specified in [RFC5751]: "the object identifiers (OIDs) are listed
in order of their preference, but SHOULD be separated logically along
the lines of their categories (signature algorithms, symmetric
algorithms, key encipherment algorithms, etc.)" As the "structure of
the SMIMECapabilities attribute is [designed] to facilitate simple
table lookups and binary comparisons in order to determine matches",
the values are given in encoded format.
In the following sections, the DER [X.690] values for the
capabilities are preceded by the algorithm's name, and, if they were
previously defined a reference for the document in which they are
defined.
1.1. Requirements Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this

document are to be interpreted as described in [RFC2119].
2. Message Digest Algorithms
[RFC3370] and [RFC5754] define the following message digest
algorithms for use with CMS:
MD5: 300a 0608 2a86 4886 f70d 0205
NOTE: Though [RFC3370] allows NULL parameters for SHA-1, SHA-224,
SHA-256, SHA-384, SHA-512, parameters MUST NOT be included in
SMIMECapability values as per [RFC5751] because there is no
differentiating by parameters for SHA-1 (e.g., output length).
SHA-1: 3007 0605 290e 0302 1a
[RFC5754] SHA-224: 300b 0609 6086 4801 6503 0402 04

3. Digital Signature Algorithms
[RFC3370], [RFC4056], [RFC5754], and [RFC5753] define the following
digital signature algorithms for use with CMS:
RSA Encryption: 3009 0608 2a86 4886 f70d 0101 01
RSA With MD5: 3009 0608 2a86 4886 f70d 0101 04

NOTE: [RFC4055] includes NULL parameters with SHA-1.

[RFC5754] DSA With SHA-256: 300b 0609 6086 4801 6503 0403 02
NOTE: [RFC5753] shows the ECDSA with SHA-1 with NULL parameter
values, but the NULL parameters should not have been included
according to [RFC5751]. The NULL is retained for backwards
compatibility.

CMS:
[RFC3274] ZLIB: 300D 060B 2A86 4886 F70D 0109 1003 08
10. Security Considerations
This document does not advocate the use of any particular algorithm.
The strength of the algorithms and applicability to their use in a
particular environment is defined in the algorithms specifications.
Unlike the S/MIME Capabilities attribute that may be included in
S/MIME messages or the S/MIME capabilities attribute that may be
included in X.509 certificates, the vCard property defined in this
document is not signed. Locally stored copies of the vCard property
should be updated as necessary when presented a signed S/MIME
capabilities instance.
11. IANA Considerations
This document registers a new vCard property [RFC6350] for S/MIME
Capabilities defined in Section 1. The registation template is
specified below:
Purpose: To specify a list of S/MIME capabilities associated with
the object that the vCard represents. Each value represents a single
SMIMECapability.
Value type: A text value (base64-encoded DER [X.690]). It can also
be reset to a single URI. [[Or just always use data: URIs?]]
Cardinality: *
ABNF:
SMIMECAPA-param = SMIMECAPA-uri-param / SMIMECAPA-text-param
SMIMECAPA-value = SMIMECAPA-uri-value / SMIMECAPA-text-value
; Value and parameter MUST match.
Turner December 14, 2013 [Page 13]
Internet-Draft vCard S/MIME Capabilities Property June 12, 2013
SMIMECAPA-uri-param = "VALUE=uri" / mediatype-param
SMIMECAPA-uri-value = URI
SMIMECAPA-text-param = "VALUE=text"
SMIMECAPA-text-value = text
SMIMECAPA-param =/ altid-param / pid-param / pref-param /
type-param / any-param
Examples:
SMIMECAPA:<... remainder of base64-encoded data ...>
