Is there a good archive of all the algorithms submitted for AES? I'd be interested especially in one that also had info on what's been broken so far, plus implementations and performance numbers. I can't find all this info on any one site, but I can't believe that one doesn't exist.

The home page for the AES is http://www.nist.gov/aes/ There is a page with current attack/break information at: http://www.ii.uib.no/~larsr/aes.html. Bruce Schneier et al have done performance comparisons of AES algorithms; links to their results at http://www.counterpane.com/AES-performance.html.
