[fitsbits] Hash Functions (MD5 is very obsolete)
Hi guys,
Apologies if you see this more than once. FYI. A reminder that MD5 has been obsolete for several years. So obsolete that even the U.S. federal government now regards its successor as similarly obsolete :-) Rob -- Begin forwarded message: From: Danny Mayer Date: July 8, 2008 4:45:30 AM GMT-07:00 To: NTP Working Group Subject: [ntpwg] Fwd: NIST's policy on Hash Functions I'm forwarding this note from a different mailing list on deprecating MD5. Since NTP uses MD5 we may need to consider this for various parts of NTP that makes use of hash functions. Comments? Danny PS: NIST'S POLICY ON HASH FUNCTIONS March 15, 2006: *The SHA-2 family of hash functions (i.e., SHA-224, SHA-256, SHA-384 and SHA-512) may be used by Federal agencies for all applications using secure hash algorithms.* Federal agencies *should* stop using SHA-1 for digital signatures, digital time stamping and other applications that require collision resistance as soon as practical, and must use the SHA-2 family of hash functions for these applications after 2010. After 2010, Federal agencies may use SHA-1 only for the following applications: hash-based message authentication codes (HMACs); key derivation functions (KDFs); and random number generators (RNGs). Regardless of use, NIST encourages application and protocol designers to use the SHA-2 family of hash functions for all new applications and protocols. (from http://csrc.nist.gov/groups/ST/hash/policy.html , I've enclosed emphased words in the original by **) |
