A video is online (it's hard to find, search for his name), along with PowerPoint slides. (Unfortunately, the video isn't set up for streaming; in order to view the it, you'll have to download the ten files, then use a fairly recent version of WinZip to concatenate the files.) EDITED TO ADD (3/26): Now on Google Video. Posted on March 25, 2008 at 1:21 PM • 11 Comments To receive these entries once a month by e-mail, sign up for the Crypto-Gram Newsletter. It also works under unix: Download all 10 parts, then "cat hellman.* >all.zip", then unzip all.zip. I used "UnZip 5.52 of 28 February 2005, by Ubuntu. Original by Info-ZIP". You will get a warning that tells you to ignore warnings, and a output file that's ok.

Search for his name at http://video.google.com Note that this is not You Tube.

I find his Q-and-A at the end disheartening. He seems to really believe that export restrictions are good because they "keep terrorists from getting inviolable secrecy." It's truly saddening, as terrorists aren't exactly opposed to smuggling things around, especially not anything as trivial to duplicate and transport as software. Perhaps the ban on hardware helps (can we still listen to the Taliban's satellite phones?), but software is a non-starter. (As mentioned in the video summary, if the original producer would this video taken down, please contact me. I wasn't certain just how libre "Libre" meant on the page...) Posted by: Josh Myer at March 25, 2008 10:18 PM Let me second Josh Myer's comments. To pillage Bruce's words, Hellman may be a brilliant guy, but I don't think he has the "security mindset". He uncritically accepts that ongoing cryptanalysis by the NSA is an integral part of maintaining the security of the world today, and it's as though he's never come across the idea that security systems are only as strong as their weakest part, and that weakest part is not usually in the cryptographic algorithms used. He considered himself a bit more radical in his younger days, with his "Luke Skywalker" attitude. Well, Bruce has often been just as critical in these pages, yet no-one would characterize him as "Luke Skywalker". :) Posted by: Lawrence D'Oliveiro at March 25, 2008 10:42 PM Dear Josh: Posted by: Jorge Ramio at March 26, 2008 3:54 AM Let's say you want to get a security video cleaned up and posted to a convenient public source. You tell Bruce about it, let him post a blog entry, and other people do the assembly and posting work for you. Almost as good as posting to Craigslist to get someone's house robbed.
