Crate caesar_cipher_enc_dec

Caesar Cipher Encryption/Decryption Library

This library provides a comprehensive implementation of the Caesar cipher, including both basic and safe (error-handling) encryption/decryption functions, as well as a command-line interface for easy usage.

Features

• Basic encryption and decryption functions
• Safe versions with input validation and error handling
• Command-line interface with multiple operation modes
• Interactive mode for repeated operations
• Brute force decryption for unknown shift values
• Support for file input/output

Quick Start

use caesar_cipher_enc_dec::caesar_cipher::{encrypt, decrypt};

let original = "Hello World";
let encrypted = encrypt(original, 3);
let decrypted = decrypt(&encrypted, 3);
assert_eq!(original, decrypted);

Modules

• caesar_cipher - Core encryption/decryption functionality
• cli - Command-line interface implementation
