Internet Engineering Task Force (IETF) S. Josefsson Request for Comments: 7468 SJD AB Category: Standards Track S. Leonard ISSN: 2070-1721 Penango, Inc. April 2015 Textual Encodings of PKIX, PKCS, and CMS Structures Abstract This document describes and discusses the textual encodings of the Public-Key Infrastructure X.509 (PKIX), Public-Key Cryptography Standards (PKCS), and Cryptographic Message Syntax (CMS). The textual encodings are well-known, are implemented by several applications and libraries, and are widely deployed. This document articulates the de facto rules by which existing implementations operate and defines them so that future implementations can interoperate. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Introduction Several security-related standards used on the Internet define ASN.1 data formats that are normally encoded using the Basic Encoding Rules (BER) or Distinguished Encoding Rules (DER) [X.690], which are binary, octet-oriented encodings. This document is about the textual encodings of the following formats: 1. Certificates, Certificate Revocation Lists (CRLs), and Subject Public Key Info structures in the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile [RFC5280]. 2. PKCS #10: Certification Request Syntax [RFC2986]. 3. PKCS #7: Cryptographic Message Syntax [RFC2315]. 4. Cryptographic Message Syntax [RFC5652].
