WebReturning to our Key Generation example with plaintext P = 10, we get ciphertext C −. C = 10 5 mod 91 RSA Decryption. The decryption process for RSA is also very straightforward. Suppose that the receiver of public-key pair (n, e) has received a ciphertext C. Receiver raises C to the power of his private key d. The result modulo n will be the ... WebRSA requires padding for entirely different reasons than CBC mode encryption. Block ciphers such as AES and (triple) DES can only be used to permute one block of plaintext to one block of ciphertext. This is not very useful as generally we would like to encrypt multiple messages of variable size.
