WebTo recap, a hill climbing algorithm is shown below: 1. Generate a random key, called the 'parent', decipher the ciphertext using this key. Rate the fitness of the deciphered text, store the result. 2. Change the key slightly (swap two characters in the key at random), measure the fitness of the deciphered text using the new key. WebFeb 9, 2024 · As we know, Hill cipher is a classic cipher in cryptography and is mostly used for encrypting text. I need to encrypt a file (such as .doc, .ppt, .jpeg, etc), and not just the contents of file. I already searched on the Internet, but I didn't find much research that focuses on file encryption.
