Internet-Draft HTTP Digest Algorithm Values Registry October 2009 1. Introduction The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" defines values for digest algorithms used in HTTP. This registry was created by [RFC3230] in 2002 and some useful values could be added to it. [[ Discussion of this draft should take place on IETF HTTP WG mailing list at ietf-http-wg@w3.org or directly to the author. ]] 1.1. Examples Examples of Instance Digest for SHA-256: Digest: SHA-256=MWVkMWQxYTRiMzk5MDQ0MzI3NGU5NDEyZTk5OWY1ZGFmNzgyZTJlO DYzYjRjYzFhOTlmNTQwYzI2M2QwM2U2MQ== 2. IANA Considerations This document makes use of the IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" specified in [RFC3230]. Accordingly, IANA has made the following registrations: Digest Algorithm: SHA-224 Description: The SHA-224 algorithm [SHS]. The output of this algorithm is encoded using the base64 encoding [RFC2045]. Reference: [SHS] [RFC2045] Digest Algorithm: SHA-256 Description: The SHA-256 algorithm [SHS]. The output of this algorithm is encoded using the base64 encoding [RFC2045]. Reference: [SHS] [RFC2045] Digest Algorithm: SHA-384 Description: The SHA-384 algorithm [SHS]. The output of this algorithm is encoded using the base64 encoding [RFC2045]. Reference: [SHS] [RFC2045] Digest Algorithm: SHA-512 Description: The SHA-512 algorithm [SHS]. The output of this algorithm is encoded using the base64 encoding [RFC2045]. Reference: [SHS] [RFC2045] Bryan Expires April 9, 2010 [Page 3]

Appendix A. Acknowledgements and Contributors Thanks to Mark Nottingham, Eran Hammer-Lahav, and Nils Maier. Appendix B. Document History (to be removed by RFC Editor before publication) [[ to be removed by the RFC editor before publication as an RFC. ]] Known issues concerning this draft: o Current registry: MD5 lists both RFC1521 and RFC20456 for base64 encoding. Should this draft update it to refer to just one? o Current registry: SHA link ( http://csrc.nist.gov/fips/fip180-1.txt ) is no longer valid. Should this draft update it? o If we update SHA in the registry, should this draft refer to SHS or RFC3174? -00 : September 08, 2009. o Initial draft. Bryan Expires April 9, 2010 [Page 4]
