Our Decrypted Text: Affine Cipher Implementation using JavaIn this implementation we will use Java programming language to encrypt and decrypt a message using Affine Cipher. So basically we will use two secret keys here, first is the Multiplicative Key (A) and the second one is Additive Key (...
The procedure includes few stages by encrypting the plain-text using affine cipher followed by Vigen猫re cipher and columnar transposition using varying key. The number of steps depends on the length of the key size used during the encryption process. Every time the new key retrieved in each ...
