The IESG has approved the following document: - 'US Secure Hash Algorithms (SHA and SHA based HMAC and HKDF)' (draft-eastlake-sha2b-07.txt) as an Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Russ Housley. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-eastlake-sha2b/ Technical Summary The United States of America has adopted a suite of secure hash algorithms (SHAs), including four beyond SHA-1, as part of a Federal Information Processing Standard (FIPS), specifically SHA-224, SHA-256, SHA-384, and SHA-512. This document makes open source code performing the SHA hash functions conveniently available to the Internet community. The sample code supports input strings of arbitrary bit length. Much of the text herein was adapted by the authors from FIPS 180-2. This document replaces RFC 4634, fixing errata and adding code for an HMAC-based extract-and-expand key derivation function, HKDF (RFC 5869). As with RFC 4634, code to perform SHA based HMACs is also included. Working Group Summary This document is not the product of any IETF WG. Document Quality The document was reviewed by Russ Housley for the IESG. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
