Internet-Draft    S/MIME Example Keys and Certificates     February 2021


1.  Introduction

   The S/MIME ([RFC8551]) development community, in particular the
   e-mail development community, benefits from sharing samples of signed
   and/or encrypted data.  Often the exact key material used does not
   matter because the properties being tested pertain to implementation
   correctness, completeness or interoperability of the overall system.
   However, without access to the relevant secret key material, a sample
   is useless.

   This document defines a small set of X.509v3 certificates ([RFC5280])
   and secret keys for use when generating or operating on such samples.

   An example certificate authority is supplied, and samples are
   provided for two "personas", Alice and Bob.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

1.2.  Terminology

   *  "Certificate Authority" (or "CA") is a party capable of issuing
      X.509 certificates

   *  "End-Entity" is a party that is capable of using X.509
      certificates (and their corresponding secret key material)

   *  "Mail User Agent" (or "MUA") is a program that generates or
      handles [RFC5322] e-mail messages.

1.3.  Prior Work

   [RFC4134] contains some sample certificates, as well as messages of
   various S/MIME formats.  That older work has unacceptably old
   algorithm choices that may introduce failures when testing modern
   systems: in 2019, some tools explicitly mark 1024-bit RSA and
   1024-bit DSS as weak.

   This earlier document also does not use the now widely-accepted PEM
   encoding for the objects, and instead embeds runnable perl code to
   extract them from the document.

   It also includes examples of messages and other structures which are
   greater in ambition than this document intends to be.  This document
   intends to focus specifically on identity and key material, as a
   starting point for other documents that can develop examples or test
   cases from them.

2.  Background

2.1.  Certificate Usage

   These X.509 certificates ([RFC5280]) are designed for use with S/MIME
   protections ([RFC8551]) for e-mail ([RFC5322]).

   In particular, they should be usable with signed and encrypted
   messages.

2.2.  Certificate Expiration

   The certificates included in this draft expire in 2052.  This should
   be sufficiently far in the future that they will be useful for a few
   decades.  However, when testing tools in the far future (or when
   playing with clock skew scenarios), care should be taken to consider
   the certificate validity window.

   Due to this lengthy expiration window, these certificates will not be
   particularly useful to test or evaluate the interaction between
   certificate expiration and protected messages.

2.3.  Certificate Revocation

   Because these are expected to be used in test suites or examples, and
   we do not expect there to be online network services in these use
   cases, we do not expect these certificates to produce any revocation
   artifacts.

   As a result, there are no OCSP or CRL indicators in any of the
   certificates.

2.4.  Using the CA in Test Suites

   To use these end-entity certificates in a piece of software (for
   example, in a test suite or an interoperability matrix), most tools
   will need to accept the example CA (Section 3) as a legitimate root
   authority.

   Note that some tooling behaves differently for certificates validated
   by "locally-installed root CAs" than for pre-installed "system-level"
   root CAs).  For example, many common implementations of HPKP



Gillmor                  Expires 22 August 2021                 [Page 4]

Internet-Draft    S/MIME Example Keys and Certificates     February 2021


   ([RFC7469]) only applied the designed protections when dealing with a
   certificate issued by a pre-installed "system-level" root CA, and
   were disabled when dealing with a certificate issued by a "locally-
   installed root CA".

   To test some tooling specifically, it may be necessary to install the
   root CA as a "system-level" root CA.

2.5.  Certificate Chains

   In most real-world examples, X.509 certificates are deployed with a
   chain of more than one X.509 certificate.  In particular, there is
   typically a long-lived root CA that users' software knows about upon
   installation, and the end-entity certificate is issued by an
   intermediate CA, which is in turn issued by the root CA.

   The examples presented in this document use a simple two-link
   certificate chain, and therefore may be unsuitable for simulating
   some real-world deployments.

   In particular, testing the use of a "transvalid" certificate (an end-
   entity certificate that is supplied without its intermediate
   certificate) is not possible with the configuration here.

2.6.  Passwords

   Each secret key presented in this draft is unprotected (it has no
   password).

   As such, the secret key objects are not suitable for verifying
   interoperable password protection schemes.

   However, the PKCS#12 [RFC7292] objects do have simple textual
   passwords, because tooling for dealing with passwordless PKCS#12
   objects is underdeveloped at the time of this draft.

2.7.  Secret key origins

   The secret keys in this document are all deterministically derived
   using provable prime generation as found in [FIPS186-4], based on
   known seeds derived via [SHA256] from simple strings.  The seeds and
   their derivation are included in the document for informational
   purposes, and to allow re-creation of the objects from appropriate
   tooling.

   All seeds used are 224 bits long (the first 224 bits of the SHA-256
   digest of the origin string), and are represented in hexadecimal.

6.  Security Considerations

   The keys presented in this document should be considered compromised
   and insecure, because the secret key material is published and
   therefore not secret.

   Applications which maintain blacklists of invalid key material SHOULD
   include these keys in their lists.

7.  IANA Considerations

   IANA has nothing to do for this document.

8.  Document Considerations

   [ RFC Editor: please remove this section before publication ]

   This document is currently edited as markdown.  Minor editorial
   changes can be suggested via merge requests at
   https://gitlab.com/dkg/lamps-samples or by e-mail to the author.
   Please direct all significant commentary to the public IETF LAMPS
   mailing list: "spasm@ietf.org"

8.1.  Document History

8.1.1.  Substantive Changes from -04 to -05

   *  PEM blobs are now "sourcecode", not "artwork"

8.1.2.  Substantive Changes from -03 to -04

   *  Describe deterministic key generation

   *  label PEM blobs with filenames in XML

8.1.3.  Substantive Changes from -02 to -03

   *  Alice and Bob now each have two distinct certificates: one for
      signing, one for encryption, and public keys to match.

8.1.4.  Substantive Changes from -01 to -02

   *  PKCS#12 objects are deliberately locked with simple passphrases

8.1.5.  Substantive Changes from -00 to -01

   *  changed all three keys to use RSA instead of RSA-PSS

   *  set keyEncipherment keyUsage flag instead of dataEncipherment in
      EE certs

9.  Acknowledgements

   This draft was inspired by similar work in the OpenPGP space by
   Bjarni Runar and juga at [I-D.bre-openpgp-samples].

   Eric Rescorla helped spot issues with certificate formats.

   Sean Turner pointed to [RFC4134] as prior work.

   Deb Cooley suggested that Alice and Bob should have separate
   certificates for signing and encryption.

   Wolfgang Hommel helped to build reproducible encrypted PKCS#12
   objects.

   Carsten Bormann got the XML "sourcecode" markup working for this
   draft.
