Question

1. Encrypt the plaintext message a dime a dozen using a Caesar cipher with a shift (to the right) of 5.

Answer 1

Caesar Cipher is a substitution cipher in which each letter of the plain text is replaced by another letter of the alphabet, which occurs a fixed number of places down the alphabet.

For example, if we have to shift 3 places to the right, then A will be replaced by D, B will be replaced by E and so on.

Now, in the above question we have to move 5 places to the right.

The Encryption will be : f inrj f itejs
