Clear text always has some non-random redundant information, especially documents, reports and other format files. During World War II, the Germans used the Enigma Enigma rotor cipher to encrypt their telegrams, creating a very efficient encryption
password by adding salt, you can increase the complexity of the password, even if the simplest password, after adding salt, can also become a complex string, which greatly improve the difficulty of password cracking. However, if the salt is hard

PBKDF2 (password-based Key derivation Function).Encrypted through a hashing algorithm. Because the hashing algorithm is unidirectional, data of any size can be converted to a fixed-length "fingerprint" and cannot be reversed. Also, the result of the
Cryptographic decryption related conceptsThree ways in which man-in-the-middle attacks are commonly used on the Internet: 1) eavesdropping 2) data tampering 3) session hijackingClassification of cryptographic algorithm protocols:
a)
It is important to understand the following for encryption and decryption:The two sides want to communicate, the middle connection may be bugged or even tampered with. The solution is to encrypt the contents of the transmission, using ciphertext to
