## 1. Introduction

The S/MIME ([RFC8551]) development community, in particular the email 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. Terminology

"Certification Authority" (or "CA"):
  a party capable of issuing X.509 certificates¶
"End Entity" (or "EE"):
  a party that is capable of using X.509 certificates (and their corresponding secret key material)¶
"Mail User Agent" (or "MUA"):
  a program that generates or handles email messages ([RFC5322])¶

### 1.2. 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 marked 1024-bit RSA and 1024-bit DSS as weak.¶

This earlier document also does not use the now widely accepted Privacy-Enhanced Mail (PEM) encoding (see [RFC7468]) for the objects and instead embeds runnable Perl code to extract them from the document.¶

It also includes examples of messages and other structures that 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

### 2.1. Certificate Usage

These X.509 certificates ([RFC5280]) are designed for use with S/MIME protections ([RFC8551]) for email ([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 document 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, none of the certificates include either an Online Certificate Status Protocol (OCSP) indicator (see `id-ad-ocsp` as defined in the Authority Information Access X.509 extension in Section 4.2.2.1 of [RFC5280]) or a Certificate Revocation List (CRL) indicator (see the CRL Distribution Points X.509 extension as defined in Section 4.2.1.13 of [RFC5280]).¶

### 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.¶

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 HTTP Public Key Pinning (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 either with 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 (`alice.encrypt.crt`; see Section 4.3) can be validated by a peer that directly trusts the example RSA CA's root cert (`ca.rsa.crt`; see Section 3.1):¶

¶
Figure 1: Validating Alice's encryption certificate directly when the issuing CA is a trust anchor

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

¶
Figure 2: Validating Alice's cert from a different trust anchor via an intermediate cross-signed CA certificate

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 document is represented as a PEM-encoded PKCS #8 ([RFC5958]) object in cleartext form (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 document.¶

### 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 SHA-256 ([SHA]) from simple strings. The validation parameters for these derivations are stored in the objects themselves as specified in [RFC8479].¶

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 recreation 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:¶
