WebAug 15, 2024 · I am aware of how i would go about doing this (without looking solutions): 1) convert the string to binary 2) loop through all character values XORing them individually with the given ciphertext 3) checking these XORd results to see which one looks "the most english" I guess im just confused on the way bytes behave in python. here is my code: WebStep 1: Let’s Stream That (Block) Cipher Here’s info on CTR mode (wikipedia). Notable points: Encryption and decryption both use the AES encryption process on the keystream bytes. All we do to encrypt or decrypt the plaintext/ciphertext is XOR with this encrypted keystream. CTR converts our block cipher into a stream cipher.
