Request for Comments: 5967 IECA
Updates: 2986 August 2010
The application/pkcs10 Media Type
This document specifies a media type used to carry PKCS #10
certification requests as defined in RFC 2986. It carries over the
original specification from RFC 2311, which recently has been moved
to Historic status, and properly links it to RFC 2986.

[RFC2311] first defined the application/pkcs10 media type. When
[RFC2633] was published, the application/pkcs10 section was dropped,
but for some reason the text was not incorporated into the PKCS #10
document [RFC2986]. [RFC2311] was moved to Historic status by
[RFC5751]. To ensure the IANA media type registration points to a
non-Historic document, this document updates [RFC2986] with the
definition of the application/pkcs10 media type and an IANA
registration based on [RFC4288].
The text for Section 2 is adapted from Section 3.7 of [RFC2311].
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. Creating a Certification Request
A typical application that allows a user to generate cryptographic
information has to submit that information to a Certification
Authority (CA), who transforms it into a certificate. PKCS #10
[RFC2986] describes a syntax for certification requests.
The details of certification requests and the process of obtaining a
certificate are beyond the scope of this memo. Instead, only the
format of data used in application/pkcs10 is defined.
2.1. Format of the application/pkcs10 Body
PKCS #10 defines the ASN.1 type CertificationRequest for use in
submitting a certification request. For transfer to a CA, this
abstract syntax needs to be encoded and identified in a unique

manner. When the media type application/pkcs10 is used, the body
