This site has some really neat pictures and a video detailing Babbage's Difference Engine. The pictures are gigapixel, so they are incredibly detailed.
A summary of why encryption wouldn't have prevented General Petraeus from getting caught. Like the quote: "If you think cryptography is the solution to your problem, you either don't understand cryptography or you don't understand your problem."
Quantum computing has teased us with its potential for some time, but we won't be seeing qubits in our laptops anytime soon. However, science has also sought to leverage quantum physics in cryptography, and a recent breakthrough will allow for quantum encryption over fiber optic cables already in use.
Since Israel's bombardment of Gaza, 44 million hacking attempts have been made on Israeli government websites. This article discusses the details of the hacking attempts, and the extent of their success or failure.
An overview of Al-Qaeda's use of encryption technology in their terrorist activities. Relevant to the debate about distributing powerful cryptography to everyone, including those with bad intentions.
The "uncrackable codes" made by exploiting the branch of physics called quantum mechanics no longer require the use of special "dark fibres" and have been sent down kilometres of standard broadband fibre.
Britain's code-breakers acknowledged Friday that an encrypted handwritten message from World War II, found on the leg of a long-dead carrier pigeon in a household chimney in southern England, has thwarted all their efforts to decode it since it was sent to them last month.
