CipherTool 🔐

Classical Cryptography — Reimagined as an Interactive Web App

Academic Project — 2023

CipherTool is a Python-based cryptography application that lets users encrypt and decrypt messages using 10 classical cipher techniques through an interactive Streamlit interface.

🌐 [https://amna-ciphertool.streamlit.app/]

🔐 Ciphers Implemented

1. Additive Cipher
2. Multiplicative Cipher
3. Affine Cipher
4. Monoalphabetic Substitution Cipher
5. Autokey Cipher
6. Vigenère Cipher
7. Playfair Cipher
8. Keyless Transposition Cipher
9. Keyed Transposition Cipher
10. Double Transposition Cipher

✨ Features

• 🔒 Encryption & Decryption — Encrypt plaintext or decrypt ciphertext using the selected cipher.
• 🔟 10 Classical Ciphers — Explore substitution, transposition, and polyalphabetic techniques.
• 🎛️ Interactive Interface — Select a cipher, operation, and required key directly from the web interface.
• 📋 Instant Results — View encrypted or decrypted output directly in the application.
• 🐍 Pure Python — Core cipher implementations built using Python without external cryptography libraries.

🛠️ Tech Stack
