File Encryption and Decryption using Vigenère Cipher

This project extends the Vigenère cipher implementation to support file encryption and decryption. It provides a command-line interface (CLI) for encrypting and decrypting files, with a progress bar to show the operation's progress.

Features

• Encrypt files using the Vigenère cipher in ECB mode.
• Decrypt files using the Vigenère cipher in ECB mode.
• Command-line interface for easy usage.
• Progress bar to visualize the encryption/decryption process.

Prerequisites

Ensure you have Rust installed on your system.

Installation

Clone the repository and navigate to the project directory:

git clone https://github.com/martian58/vigenc.git
cd vigenc

Building the Project

To build the project, use the following command:

cargo build

For a release build, use:

cargo build --release

Running the Project

Command-Line Interface

The project provides a command-line interface for encrypting and decrypting files. The available options are:

• --input or -i: The input file to use (required).
• --output or -o: The output file to use (optional).
• --key or -k: The encryption/decryption key (optional, will prompt if not provided).
• --decrypt or -d: Decrypt the input file instead of encrypting.

Example Usage

Encrypt and Overwrite the Input File

cargo run --bin vigenc -- --input input_file.txt

Encrypt and Create a New Output File

cargo run --bin vigenc -- --input input_file.txt --output output_file.txt

Decrypt and Overwrite the Input File

cargo run --bin vigenc -- --input encrypted_file.txt --decrypt

Decrypt and Create a New Output File

cargo run --bin vigenc -- --input encrypted_file.txt --output decrypted_file.txt --decrypt
