Des weakness attack
The Data Encryption Standard is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography. Developed in the early 1970s at IBM and based on an earlier … See more The origins of DES date to 1972, when a National Bureau of Standards study of US government computer security identified a need for a government-wide standard for encrypting unclassified, sensitive information. See more DES is the archetypal block cipher—an algorithm that takes a fixed-length string of plaintext bits and transforms it through a series of complicated operations into another See more Simplified DES (SDES) was designed for educational purposes only, to help students learn about modern cryptanalytic techniques.

EDE stands for Encrypt-Decrypt-Encrypt.) DES has 64 known weak keys, including so-called semi-weak keys and possibly-weak keys [Schneier95, pp 280-282]. The likelihood of picking one at random is negligible.

WebPP is a rare disorder that causes sudden, temporary attacks of muscle weakness, stiffness, or paralysis. PP is a genetic disorder passed down from a parent. The inheritance is dominant, meaning you have a chance of getting it if even one parent has the genetic defect for PP. PP episodes can start in childhood or adulthood.
