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...

Write a function called char_counter that counts the number of a certain character in a text file. The function takes two input arguments, fname, a char vector of the filename and character, the char it counts in the file. The function returns charnum, the number of characters found. If the file is not found or character is not a valid char, the function return -1. As an example, consider the following run. The file "simple.txt" contains a single line: "This...
