Cryptography has been the weapon of choice for generations of spies, generals, and governments. Today, crypto is the foundation for secure communications, e-commerce, and online anonymity. Yet crypto still gets cracked or brute-forced. What gives? Crypto is like a parachute -- it's dangerous to roll your own unless you're a professional. Nobody can make you a pro in 2 1/2 hours, but this workshop will give you a working knowledge of cryptography -- from the fundamentals to commercial and military-grade ciphers. Not only will you understand what happens "under the hood", but you'll know the difference between major encryption algorithms, and have better insight into what ciphers are better than others for particular applications.
