TopicLet God be God, Caesar's Caesar.Here we introduce the world's most popular Caesar password Caesar cipher, also known as the shift password.The shift password, which is the letter in the password, is shifted according to the specified number.A common case is the ROT13 password, which shifts the letters to 13 positions. By ' A '? ' N ', ' B '? ' O ', and so on.Write a ROT13 function, implement input encryption string, output decrypt string.All lett

In CFB mode, the previous ciphertext packet is sent back to the input of the cryptographic algorithm. The so-called feedback, which refers to the meaning of the return input, as shown:In the ECB mode and CBC mode, the plaintext packet is encrypted by the cipher algorithm, whereas in the CFB mode, the plaintext packet is not encrypted directly by the cipher algorithm.We can see the difference between the CBC

CTR Mode is a stream cipher that generates a key stream by encrypting successive accumulated counters, and in CTR mode, each packet corresponds to a successive cumulative counter, and the key stream is generated by encrypting the counter. The final cipher packet is obtained by XOR the bit sequence encrypted by the counter and the plaintext packet, as shown in:The method for generating the counter is as foll
