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

1. 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.
