Sorry for the brain fart. I've been up without sleep for a very long time... Ever since I attempted to attend the Austin CP meeting which didn't take place, then I was in Dallas most of yesterday and last night. I am running on nicotine, caphine, and.... Its *Dr. Dobbs Journal.* Appologies to the publishers and for those who are sending me corrections...
For non Dr. Jobbs subscribers:
Dr. Jobbs Journal has several articles on encryption, including an article by Ian and Dave on the Netscape crack, multiple encryption, and using MD5 for passwords.
Also, there is a very interesting article by the author of Applied Cryptography (the Big Mac himself), looking at differential and linear cryptoanalysis of the DES algorithm.
There are also some compression articles as well.
