Answer

If one character in the plain text is changed in the Playfair Cipher, explain for example how many characters are changed in the ciphertext for all possible cases.

Answer: According to the process of diffusion, if single bit of plaintext is changed, then half of the bits are changed in cipher text. So for example, if a single character is changed in the plain text, then half of the characters are changed in the cipher text.

Let me know if you have any doubts or if you need anything to change. 

If you are satisfied with the solution, please leave a +ve feedback : ) Let me know for any help with any other questions.

Thank You!

Vigenère Cipher. In the Vigenère Cipher, we use a special keyword to encrypt a message. We represent each letter of the alphabet as a number from 0-25. In order, we add each letter from the keyword to the message and mod by 26. If the keyword is shorter than the message, we simply repeat the keyword. For example, lets say that the message is HOWSTUFFWORKS and the keyword is CIPHER. The following table shows how we can find the final...

USE C programming (pls label which file is libcipher.h and libcipher.c) Q4) A shift cipher is one of the simplest encryption techniques in the field of cryptography. It is a cipher in which each letter in a plain text message is replaced by a letter some fixed number of positions up the alphabet (i.e., by right shifting the alphabetic characters in the plain text message). For example, with a right shift of 2, ’A’ is replaced by ’C’, ’B’ is...
