A cryptographic hash function takes an input and returns a fixed size string that corresponds to it, called a hash. Cryptographic hashes have a lot of uses, some of which are: detecting data changes, storing or generating passwords, making unique keys in databases and ensuring message integrity. This video will mostly cover detecting file changes, but I hope it gets your mind going in the right direction for how hashes can be used. Specifically covered will be tools for creating MD5 hashes in Windows and Linux.

China is refusing to guarantee that it won’t censor the Internet during this summer’s Olympic Games, but insists that the international media will still be able to function normally. Officials from China’s Technology Ministry took a somewhat odd opportunity to speak about its censorship plans during a press conference after the Olympic torch relay crossed Mount Everest. They said that while the government would be able to “guarantee as much [access] as possible,” there’s no way that China would turn off the Great Firewall entirely during the Games.
“China has always been very cautious when it comes to the Internet,” Technology Minister Wan Gang said, according to Reuters. “I’ve not got any clear information about which sites will be shut or screened. But to protect the youth there are controls on some unhealthy web sites.”

Web application Glasnost simulates BitTorrent downloads on your computer to determine whether or not your internet service provider (ISP) is throttling your BitTorrent transfers. It does so by measuring the difference between your regular download speed and your BitTorrent download speed, testing against different ports and other variables to get a better idea of what exactly is being throttled. The tool is aggregating the results of the test, which the site is publishing to encourage greater transparency among ISPs. If your ISP turns out to be throttling your BitTorrent traffic, you can still avoid the throttling if you know the right tricks.

Members of the Gnucitizen community have announced the House of Hackers Project. House of Hackers is intended to be a social network where hackers can make contacts, form groups, and exchange views. In addition, organizations and companies in the “hacker recruitment market” can post calls for project tenders, creating a kind of jobs board for members of the network.
Companies will pay a fee for each call for tenders to find security consultants or penetration testing teams. The network founders want to use the proceeds for various research projects that will soon be up and running. So far, more than 100 members have registered for the newly founded network.
The network is intended to give companies the opportunity to draw on a broad pool of security experts, while allowing “gifted security consultants to escape from their boring everyday routine and start a new life full of excitement and new opportunities”. However, no clear statement has been made about how ethical or technical standards will be assured. Indeed, the site states “The market is open and it is only supervised by the House of Hackers board members”. This should raise very real concerns such as recently led to the formation of a validation body for penetration testers in the UK.
I suggest signing up, I am one of early adopters!

Our gadget-obsessed brothers at Gizmodo report that many AT&T hotspots—including Starbucks and Barnes and Noble—have started offering free Wi-Fi access to iPhone users. With a little ingenuity, the same free Wi-Fi access can be granted to your laptop. Using it from your iPhone, you just connect to the hotspot and give the site your iPhone number. To get the same access on your laptop, the key is to fool the hotspot into thinking your browser is still an iPhone. Here’s how:
To masquerade as an iPhone, you’ll need to tweak your browser’s user agent, which web sites use to identify your browser when you connect to the site. In Firefox, you can install the previously mentioned User Agent Switcher. In Safari, you can select the iPhone user agent through the Develop menu (which you can enable by navigating to Preferences -> Advanced and checking “Show Develop menu in menu bar.” Likewise, Opera has user agent switching built in. On the non-Safari browsers, you’ll have to manually add a new iPhone user agent like so.
new-user-agent.pngNow that you’re all set up with your spoofed iPhone user agent, head to the hotspot page and enter your iPhone number (or, if you’ve got permission, maybe the number of an iPhone owner you know).* Once you’re done, you should hopefully have free hotspot access from your full screen rather than your tiny iPhone screen.
I haven’t actually been able to verify this yet (though there are reports of success), so if you give it a try, let’s hear how it worked for you in the comments.
