encryptor

🔐 Encryptor

A Python desktop application for encrypting and decrypting text files using a custom character-substitution cipher.

---

✨ Features

• Encrypt text files with a custom encoding scheme
• Decrypt previously encrypted files back to plain text
• GUI-based interface — no command line needed
• Error logging to track any issues during processing
• Modular design: separate encrypt.py and decrypt.py modules

📝 Notes

• Version 2.1 — built through 2 major iterations (2.0 → 2.1).
• The encryption approach is a custom-designed cipher rather than a standard algorithm (e.g., AES) — built as a learning exercise in file I/O, string manipulation, and GUI development.
• A great project for understanding the basics of how encryption and decryption pipelines work.
