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.

1. 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].
