Result = '' for character in input_string: ''' # Set default alphabet to lower and upper case english chars > encrypt('a lowercase alphabet', 5, 'abcdefghijklmnopqrstuvwxyz')

'bpm 圜qks jzwEv nwF rCuxA wDmz Bpm tiHG lwo' > encrypt('The quick brown fox jumps over the lazy dog', 8) Our final message would be 'Jgnnq, ecrvckp' ('Z' would shift to 'a' then 'b' and so on). Our letter is at the end of the alphabet, we just start at the beginning Since 'J' is two letters away, and so on. We can then encode the message, one letter at a time.

'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' Where very character in the plain-text is shifted by a certain number knownĪnd our alphabet is made up of lower and uppercase letters: The caesar cipher is named after Julius Caesar who used it when sending * A string containing the encoded cipher-text Specified, the standard english alphabet with upper and lowercase * alphabet (None): the alphabet used to encode the cipher, if not * key: the number of letters to shift the message by * input_string: the plain-text that needs to be encoded

While encrypting the message, whitespace, special characters and numbers remain unaffected.Def encrypt( input_string: str, key: int, alphabet: str | None = None) -> str:Įncodes a given string with the caesar cipher and returns the encoded.

Whitespace, special characters, and numbers do not take into consideration keywords although you can put them in there.

All the messages are encoded in uppercase.

Lets encode the given message 'Zombie Here' This means 'A' means 'S', 'B' means 'E' and 'C' means 'C' and so on. When 'secret' keyword is used, the new encrypting text becomes :Įncrypting : S E C R T A B D F G H I J K L M N O P Q U V W X Y Z Plain Text : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Encrypting the message “knowledge is power” using the keyword “Kryptos”: Encrypting the message: Knowledge is PowerĬiphered String : ZLJEFT DTOT Take the first example, we used 'secret' keyword there. With KRYPTOS as the keyword, all As become Ks, all Bs becoming Rs, and so on. Plaintext: A B C D E F G H I J K L M N O P Q R S T U V W X Y ZĮncrypted: K R Y P T O S A B C D E F G H I J L M N Q U V W X Z The second line of input contains the string which you have to encrypt. The first line of input contains the keyword which you wish to enter.
