1. Introduction
JSON Web Key ([JWK]) describes an abstract data structure to
represent public keys using JavaScript Object Notation (JSON)
[RFC4627]. The JSON Web Algorithms ([JWA]) define specific key
representations for raw asymmetric key types, such as RSA [RFC3447]
or Elliptic Curve [DSS]. However, there are times when it is
desirable to represent a Public Key Infrastructure (X.509)
certificate chain, such as to associate with a JSON Web Encryption
([JWE]) or JSON Web Signature ([JWS]) object. This document
specifies an approach which encodes a chain of PKIX certificates as
an array of strings within a JWK object.
PKIX certificates have a number of advantages, such as an established
process of certification and attribution of entities. It is also
sometimes desirable for JSON-based cryptographic operations to
support the existing and widespread deployment of PKIX-based
technologies.
2. Terminology
This document inherits JSON Web Algorithms (JWA)-related terminology
from [JWA], JSON Web Encryption (JWE)-related terminology from [JWE],
and JSON Web Key (JWK)-related terminology from [JWK]. Security-
related terms are to be understood in the sense defined in [RFC4949].
The capitalized 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].

3. PKIX Key Type
The "PKIX" key type is used to contain a chain of PKIX certificates.
The following parameters are defined:
3.1. 'x5c' (X.509 Certificate Chain) Parameter
The REQUIRED "x5c" parameter contains a chain of one or more PKIX
certificates [RFC5280]. The certificate chain is represented as an
array of certificate value strings. Each string in the array is a
DER [ITU.X690.1994] PKIX certificate encoded as base64 [RFC4648] (not
base64url). The array MUST have at least one value, which MUST be
the PKIX certificate of the actor (e.g., the singer of a [JWS], or a
recipient of a [JWE]). Each additional value of the array (if any)
MUST be the PKIX certificate that certifies the previous certificate.
4. Examples
The following is a non-normative example of a JWK Set containing a
single JWK utilizing the PKIX Key Type ("kty") defined in this
document.
