    • @milhousevanhoutan9235
      @milhousevanhoutan9235 Před 7 měsíci

      the math is:
      Encryption: C = (p + k) mod 26
      Decryption: p = (C - k) mod 26
      Where C is ciphertext, p is plaintext, using the alphabet indexed from 0-25, and k is the shift. For a Caesar Cipher by definition/default the shift is 3. k is easily derived from the decryption equation, but given that it's mod 26 there's only 25 possibilities so it's easy to brute force.
      This should be trivially easy to convert to code. I don't write C#

  • @muhammadusman5521
    @muhammadusman5521 Před 2 lety +1

    for the last encrypted digit B having index 1. how do we decrypt it (1 - 3) = -2 ??how do we doo that

    • @bilaltahirhacoglu3762
      @bilaltahirhacoglu3762 Před 2 lety +1

      (1-3)mod26 = -2 + 26= 24 which is 'y'

    • @mdafeef3911
      @mdafeef3911 Před 2 lety +1

      Add 26 to -2. You will get the answer 24 ---> Y

    • @nishoscribbles
      @nishoscribbles Před rokem

      By default it's 3 but in our university exam they made the last digit of our roll numbers the shift key... So 3 IS THE DEFAULT KEY, you'll be using that

      if in answer the value for key will not be given in that case we will take the key value as 3.

    sir there is one wrong value in encryption which is 'm', the encryption of 'm' is 's'.....not 'p'
    like that
    c=(p+k) mod 26
    =(15+3) mod 26
    =18 mod 26
    =18
    =s
