Caesar cipher encryption, decryption, and brute-force cracking CLI with frequency analysis.

This is a quick overview — security theory, architecture, and full walkthroughs are in the learn modules.

What It Does

  • Encrypt text using Caesar cipher with a specified shift key
  • Decrypt ciphertext back to plaintext with the original key
  • Brute-force crack unknown ciphertext by testing all 26 shifts
  • Frequency analysis ranking to identify the most likely plaintext
  • Clean Rich terminal output with colored tables

Quick Start

uv tool install caesar-salad-cipher
caesar-cipher encrypt "HELLO WORLD" --key 3

[!TIP] This project uses just as a command runner. Type just to see all available commands.

Install: curl -sSf https://just.systems/install.sh | bash -s -- --to ~/.local/bin

Commands

Command Description
