Steganography Tutorial - Hide Messages In Images
Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it

Martin Hellman: The Wisdom of Foolishness
Stanford Engineering Hero Lecture When Martin Hellman started working in cryptography in the early 1970s, his colleagues told him he was crazy to do so; he couldn't possibly compete with the U.S. National Security Agency (NSA) and its enormous budget. He was also warned that if he did acco
