SHA-3

Icon from the Tango Desktop Project

In 2007, it seemed all we read about in crypto circles were successful attacks against the MD5 and SHA family of hashing algorithms. Well after a six year contest, NIST is about ready to announce a suitable replacement to be dubbed SHA-3.

Interestingly, Bruce Schneier isn't so enthusiastic:

It’s not that the new hash functions aren’t any good, it’s that we don’t really need one. [..] We didn’t know [in 2006] how long the various SHA-2 variants would remain secure. But it’s 2012, and SHA-512 is still looking good.

That said, Skein and it's Threefish block cipher look really intriguing. I eschewed Rijndael/AES and use Twofish for all my personal crypto.
