WebHill cipher is one of the techniques to convert a plain text into ciphertext and vice versa. There are two parts in the Hill cipher – Encryption and Decryption. Encryption – Plain text … WebThe Caesar Cipher program in C is a simple and old method to convert data into secret code. It provides a method to encrypt and decrypt the given information. It shifts the current character to a couple of characters in a cyclic manner. As it is simple it is easy to implement and thus, also easy to crack. It is friendly for non-complex systems.
