In cryptography, black-bag cryptanalysis is a euphemism for the acquisition of cryptographic secrets via burglary, or other covert means – rather than mathematical or technical cryptanalytic attack. The term refers to the black bag of equipment that a burglar would carry or a black bag operation. As with rubber-hose cryptanalysis, this is technically not a form of cryptanalysis; the term is used sardonically. However, given the free availability of very high strength cryptographic systems, this type of attack is a much more serious threat to most users than mathematical attacks because it is often much easier to attempt to circumvent cryptographic systems (e.g. steal the password) than to attack them directly. Regardless of the technique used, such methods are intended to capture highly sensitive information e.g. cryptographic keys, key-rings, passwords or unencrypted plaintext. The required information is usually copied without removing or destroying it, so capture often takes place without the victim realizing it has occurred. (Wikipedia).

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

27c3: News Key Recovery Attacks on RC4/WEP (en)
Speaker: Martin Vuagnoux In this paper, we present several weaknesses in the stream cipher RC4. First, we present a technique to automatically reveal linear correlations in the PRGA of RC4. With this method, 48 new exploitable correlations have been discovered. Then we bind these new b

Cryptanalysis of Vigenere cipher: not just how, but why it works
The Vigenere cipher, dating from the 1500's, was still used during the US civil war. We introduce the cipher and explain a standard method of cryptanalysis based on frequency analysis and the geometry of vectors. We focus on visual intuition to explain why it works. The only background
