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 RSA certification authority is supplied, and sample RSA
   certificates are provided for two "personas", Alice and Bob.

   Additionally, an Ed25519 ([RFC8032]) certification authority is
   supplied, along with sample Ed25519 certificates for two more
   "personas", Carlos and Dana.

   This document focuses narrowly on functional, well-formed identity
   and key material.  It is a starting point that other documents can
   use to develop sample signed or encrypted messages, test vectors, or
   other artifacts for improved interoperability.

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

   *  "Certification 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.

   [RFC8410] includes an example X25519 certificate that is certified
   with Ed25519, but it appears to be self-issued, and it is not
   directly useful in testing an S/MIME-capable MUA.

2.  Background

Gillmor                 Expires 15 November 2021                [Page 4]
Internet-Draft    S/MIME Example Keys and Certificates          May 2021

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, as part of test suites and interoperability frameworks.

   All end-entity and intermediate CA certificates are marked with
   Certificate Policies from [TEST-POLICY] indicating that they are
   intended only for use in testing environments.  End-entity
   certificates are marked with policy 2.16.840.1.101.3.2.1.48.1 and
   intermediate CAs are marked with policy 2.16.840.1.101.3.2.1.48.2.

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 either the Example RSA CA (Section 3) or the
   Example Ed25519 CA (Section 6) as a legitimate root authority.

Gillmor                 Expires 15 November 2021                [Page 5]
Internet-Draft    S/MIME Example Keys and Certificates          May 2021

   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
   ([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 example end-entity certificates in this document can be used with
   either a simple two-link certificate chain (they are directly
   certified by their corresponding root CA), or in a three-link chain.

   For example, Alice's encryption certificate (Section 4.3,
   "alice.encrypt.crt") can be validated by a peer that directly trusts
   the Example RSA CA's root cert (Section 3.1, "ca.rsa.crt"):

   ╔════════════╗  ┌───────────────────┐
   ║ ca.rsa.crt ╟─→│ alice.encrypt.crt │
   ╚════════════╝  └───────────────────┘

   And it can also be validated by a peer that only directly trusts the
   Example Ed25519 CA's root cert (Section 6.1, "ca.25519.crt"), via an
   intermediate cross-signed CA cert (Section 3.3, "ca.rsa.cross.crt"):

   ╔══════════════╗  ┌──────────────────┐  ┌───────────────────┐
   ║ ca.25519.crt ╟─→│ ca.rsa.cross.crt ├─→│ alice.encrypt.crt │
   ╚══════════════╝  └──────────────────┘  └───────────────────┘

   By omitting the cross-signed CA certs, it should be possible to test
   a "transvalid" certificate (an end-entity certificate that is
   supplied without its intermediate certificate) in some
   configurations.

2.6.  Passwords

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

Gillmor                 Expires 15 November 2021                [Page 6]
Internet-Draft    S/MIME Example Keys and Certificates          May 2021

   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 RSA 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
   secret Ed25519 and X25519 keys in this document are all derived by
   hashing a simple string.  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 RSA seeds used are 224 bits long (the first 224 bits of the
   SHA-256 digest of the origin string), and are represented in
   hexadecimal.

3.  Example RSA Certification Authority

   The example RSA Certification Authority has the following
   information:

   *  Name: "Sample LAMPS RSA Certification Authority"

3.1.  RSA Certification Authority Root Certificate

   This cerificate is used to verify certificates issued by the example
   RSA Certification Authority.

9.  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.

10.  IANA Considerations

   IANA has nothing to do for this document.

11.  Document Considerations

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

   *  Added S/MIME Capabilities extension for Carlos and Dana's
      encryption keys, indicating preferred ECDH parameters.

   *  Ensure no serial numbers are negative.

   *  Encode keyUsage extensions in minimum-length BIT STRINGs.

11.1.3.  Substantive Changes from draft-ietf-*-00 to draft-ietf-*-01

   *  Added Curve25519 sample certificates (new CA, Carlos, and Dana)

11.1.4.  Substantive Changes from draft-dkg-*-05 to draft-ietf-*-00

   *  WG adoption (dkg moves from Author to Editor)

11.1.5.  Substantive Changes from draft-dkg-*-04 to draft-dkg-*-05

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

11.1.6.  Substantive Changes from draft-dkg-*-03 to draft-dkg-*-04

   *  Describe deterministic key generation

   *  label PEM blobs with filenames in XML

11.1.7.  Substantive Changes from draft-dkg-*-02 to draft-dkg-*-03

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

11.1.8.  Substantive Changes from draft-dkg-*-01 to draft-dkg-*-02

   *  PKCS#12 objects are deliberately locked with simple passphrases

11.1.9.  Substantive Changes from draft-dkg-*-00 to draft-dkg-*-01

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

   *  set keyEncipherment keyUsage flag instead of dataEncipherment in
      EE certs
