WebIn cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: . A 0 = A, A A = 0, A B = B A, (A B) C = A (B C), (B A) A = B 0 = B,. For example where denotes the exclusive disjunction (XOR) operation. This operation is sometimes called modulus 2 addition (or subtraction, which is identical).

WebJun 11, 2024 · Continuing with the simple example above, the private key of Site B is made from its public key as follows. private decrypt exponent = (public encrypt exponent) -1 Mod f (n) ∵ public encrypt exponent = 7 , and f (n) = 40. ∴ (private decrypt exponent x 7) Mod 40 = 1. ∴ private decrypt exponent = 23. WebImagine Alice and Bob decided to communicate using the Caesar Cipher First, they would need to agree in advance on a shift to use-- say, three. So to encrypt her message, Alice would need to apply a shift of three to each letter in her original message. So A becomes D, B becomes E, C becomes F, and so on.
