[CISSP-D] NIST dropping DES

Not exactly following the thread here, but since it's about crypto: the DES 
standard is no longer being used by NIST due to it's low security and they 
have adopted AES as a better choice. Also, SHA-1 may be dropped in favor of 
stronger SHA algorithms. SHA-1 is breakable, according to a few researchers 
who have been trying to break it, but the final results aren't out yet. Read 
all about it: http://csrc.nist.gov/index.html (see CSD News on right side of 
page).
