Internet Engineering Task Force (IETF) P. Hoffman Request for Comments: 5912 VPN Consortium Category: Informational J. Schaad ISSN: 2070-1721 Soaring Hawk Consulting June 2010 New ASN.1 Modules for the Public Key Infrastructure Using X.509 (PKIX) Abstract The Public Key Infrastructure using X.509 (PKIX) certificate format, and many associated formats, are expressed using ASN.1. The current ASN.1 modules conform to the 1988 version of ASN.1. This document updates those ASN.1 modules to conform to the 2002 version of ASN.1. There are no bits-on-the-wire changes to any of the formats; this is simply a change to the syntax. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. 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). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.

RFC 5912 New ASN.1 for PKIX June 2010 1. Introduction Some developers would like the IETF to use the latest version of ASN.1 in its standards. Most of the RFCs that relate to security protocols still use ASN.1 from the 1988 standard, which has been deprecated. This is particularly true for the standards that relate to PKIX, Cryptographic Message Syntax (CMS), and S/MIME. This document updates the following RFCs to use ASN.1 modules that conform to the 2002 version of ASN.1 [ASN1-2002]. Note that not all the modules are updated; some are included to simply make the set complete. o RFC 2560, PKIX Online Certificate Status Protocol (OCSP) [RFC2560] o RFC 2986, PKCS #10 certificate request [RFC2986] o RFC 3279, PKIX algorithms and identifier [RFC3279] o RFC 3852, contains PKIX attribute certificates, version 1 [RFC3852] o RFC 4055, Additional Algorithms and Identifiers for RSA Cryptography [RFC4055] o RFC 4210, PKIX CMP (Certificate Management Protocol) [RFC4210] o RFC 4211, PKIX CRMF (Certificate Request Message Format) [RFC4211] o RFC 5055, PKIX SCVP (Server-based Certificate Validation Protocol) [RFC5055] o RFC 5272, Certificate Management over CMS (CMC) [RFC5272] o RFC 5280, PKIX certificate and Certificate Revocation List (CRL) profile [RFC5280] (both the implicit and explicit modules) o RFC 5755, PKIX attribute certificates, version 2 [RFC5755] Note that some of the modules in this document get some of their definitions from places different than the modules in the original RFCs. The idea is that these modules, when combined with the modules in [RFC5911] can stand on their own and do not need to import definitions from anywhere else. Also note that the ASN.1 modules in this document have references in their text comments that need to be looked up in original RFCs, and that some of those references may have already been superseded by later RFCs. Hoffman & Schaad Informational [Page 3]
RFC 5912 New ASN.1 for PKIX June 2010 The document also includes a module of common definitions called "PKIX-CommonTypes". These definitions are used here and in [RFC5911]. The document also includes a module of common definitions called "AlgorithmInformation". These definitions are used here and in [RFC5911]. 1.1. Design Notes The modules in this document use the object model available in the 2002 ASN.1 documents to a great extent. Objects for each of the different algorithm types are defined. Also, all of the places where the 1988 ASN.1 syntax had ANY holes to allow for variable syntax now use objects. Much like the way that the PKIX and S/MIME working groups use the prefix of id- for object identifiers, this document has also adopted a set of two-, three-, and four-letter prefixes to allow for quick identification of the type of an object based on its name. This allows, for example, the same back half of the name to be used for the different objects. Thus, "id-sha1" is the object identifier, while "mda-sha1" is the message digest object for "sha1". One or more object sets for the different types of algorithms are defined. A single consistent name for each different algorithm type is used. For example, an object set named PublicKeys contains the public keys defined in that module. If no public keys are defined, then the object set is not created. When importing these object sets into an ASN.1 module, one needs to be able to distinguish between the different object sets with the same name. This is done by using both the module name (as specified in the IMPORT statement) and the object set name. For example, in the module for RFC 5280: PublicKeys FROM PKIXAlgs-2008 { 1 3 6 1 5 5 7 0 995 } PublicKeys FROM PKIX1-PSS-OAEP-Algorithms { 1 3 6 1 5 5 7 33 } PublicKeyAlgorithms PUBLIC-KEY ::= { PKIXAlgs-2008.PublicKeys, ..., PKIX1-PSS-OAEP-Algorithms.PublicKeys } Hoffman & Schaad Informational [Page 4]
