EnciphDeWord

Inspired by Cipher System using SpreadSheet by @Stu Schawartz

EnciphDeWord is a Python-based command‑line application designed to help beginners explore and understand classic cryptography. It provides an interactive environment where users can encrypt and decrypt text using a variety of algorithms—from simple substitution methods to more advanced matrix‑based ciphers. Each algorithm is implemented from scratch in pure Python, allowing users to see exactly how plaintext is transformed into ciphertext and back.
