Internet Engineering Task Force (IETF) Q. Dang Request for Comments: 5758 NIST Updates: 3279 S. Santesson Category: Standards Track 3xA Security ISSN: 2070-1721 K. Moriarty EMC D. Brown Certicom Corp. T. Polk NIST January 2010 Internet X.509 Public Key Infrastructure: Additional Algorithms and Identifiers for DSA and ECDSA Abstract This document updates RFC 3279 to specify algorithm identifiers and ASN.1 encoding rules for the Digital Signature Algorithm (DSA) and Elliptic Curve Digital Signature Algorithm (ECDSA) digital signatures when using SHA-224, SHA-256, SHA-384, or SHA-512 as the hashing algorithm. This specification applies to the Internet X.509 Public Key infrastructure (PKI) when digital signatures are used to sign certificates and certificate revocation lists (CRLs). This document also identifies all four SHA2 hash algorithms for use in the Internet X.509 PKI. 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 This specification defines the contents of the signatureAlgorithm, signatureValue, and signature fields within Internet X.509 certificates and CRLs when these objects are signed using DSA or ECDSA with a SHA2 hash algorithm. These fields are more fully described in RFC 5280 [RFC5280]. This document also identifies all four SHA2 hash algorithms for use in the Internet X.509 PKI. This document profiles material presented in the "Secure Hash Standard" [FIPS180-3], "Public Key Cryptography for the Financial Services Industry: The Elliptic Curve Digital Signature Standard (ECDSA)" [X9.62], and the "Digital Signature Standard" [FIPS186-3]. This document updates RFC 3279 [RFC3279] Sections 2.1, 2.2.2, and 2.2.3. Note that RFC 5480 [RFC5480] updates Sections 2.3.5, 3 (ASN.1 Module), and 5 (Security Considerations) of RFC 3279.
