WebA Caesar cipher (or shift cipher) is a simple encryption method. Each letter in what's called plaintext (the un-encrypted text) shifts some fixed number of positions along the alphabet. After Z, the shifting "wraps around" and goes back to A. For example, “ABCZ123abcz” shifted by 4 would become “EFGD567efgd”. This technique is named ... Webvoid caesar_decipher(unsigned char cryptotext[MAX_STR_LEN], unsigned char password[MAX_STR_LEN]) // This function reverses the encryption process and returns the original // text given the encrypted string and the password used to encrypt it.

You don't need to differentiate between decode and encode, you can simply provide negative shift. You can hide the big lambda into a char -> char function. You actually don't need the string -> string nor vector -> vector implementations. encodeStr is a terrible name :) green architecture uk
