The Caesar Cipher encryption rule can be expressed mathematically as: c = (x + n) % 26 Where c is the encoded character, x is the actual character, and n is the number of positions we want to shift the character x by. We're taking mod with 26 because there are 26 letters in the English alphabet. Caesar Cipher in Python Caesar Cipher Using Python. Now, we will be writing the code for implementing the caesar cipher algorithm. We shall be defining two functions - one for encryption and another for decryption. Lets us look at both separately. Encryption algorithm explaination. To perform encryption, we will be creating a user defined function - caesar_encryption(): The function will accept two arguments. Caesar Cipher Technique is the simple and easy method of encryption technique. It is simple type of substitution cipher. Each letter of plain text is replaced by a letter with some fixed number of positions down with alphabet. The following diagram depicts the working of Caesar cipher algorithm implementation â . In a simple way, it reorganize all the letter from a sentence based on a shifted alphabet. For example, if we choose a right shift..
Your function prints the result instead of returning it, which gets the job done but makes the function less reusable. Suppose that you want to read a textfile (using Python), encrypt it using Caesar cipher, and then write the ciphertext to a new textfile. Or that you have a list of strings and want to make a new list with these strings encrypted. What will you do? Sure you can make other functions to get this done, but if you make this function return the rotated text you can. In python it is recomendend to do this kind of replacement with a comprehesnion: def cipherencrypt(word, key): return .join( chr(((ord(i) - ord('a')) + key) % 26 + ord('a')) for i in word.lower() ) Your cipher does not currently support space or any non latin character. If passed a non latin character, like space, your program will not be able to decrypt it. consider expanding your range to all printable characters or adding a special case for space
