Caesar

A fast, robust command-line tool for encrypting and decrypting text and binary files using a customizable Caesar cipher.

📥 Download & Install

Option 1: Pre-compiled Binaries (Recommended)

1. Go to the Releases page.
2. Download the executable for your operating system (Windows, macOS, or Linux).
3. Place the executable in a directory that is in your system's PATH.

Option 2: Using Cargo (Rust Developers) If you have the Rust toolchain installed, you can build and install directly from source:

cargo install --path .

🚀 Usage

The CLI requires an input file, a mode (encrypt or decrypt), and optionally a file type (text or binary), a shift key, or a password.

Encrypt a text file:

caesar input.txt -m encrypt -t text -s 5

Encrypt a binary file with a password:

caesar image.png -m encrypt -t binary -k "my_secret_password"

Decrypt a file:

caesar output/encrypted/input.txt -m decrypt -k "my_secret_password"

Use caesar --help to see all available options.

🗑️ Uninstall

If you installed via Cargo, run:

cargo uninstall caesar
