Cryptography weakness

WebWeak generators generally take less processing power and/or do not use the precious, finite, entropy sources on a system. While such PRNGs might have very useful features, these … WebSymmetric encryption is also called “secret key” encryption because the key must be kept secret from third parties. Strengths of this method include speed and cryptographic strength per bit of key; however, the major weakness is that the key must be securely shared before two parties may communicate securely.

WebWeaknesses. Since the affine cipher is still a monoalphabetic substitution cipher, it inherits the weaknesses of that class of ciphers. The Caesar cipher is an Affine cipher with a = 1 since the encrypting function simply reduces to a linear shift. The Atbash cipher uses a = −1.
