🛡️ Secure Journal App

Your thoughts deserve the same protection as your passwords. A beautifully minimal, end-to-end secure journal built with Rust — where privacy, performance, and design meet.

---

✨ Overview

Secure Journal App is a private journaling tool built in Rust that keeps your notes safe and encrypted. Every entry is protected with Argon2 password hashing and rpassword-based encryption, ensuring that your data stays truly yours — even offline.

This isn’t just a journal — it’s a fortress for your thoughts.

🔐 Features

• 🧠 Encrypted Entries — Uses rpassword to handle passwords securely without exposing them in terminal input.
• 🧩 Strong Password Hashing — Implements argon2 to hash and verify master passwords.
• ⚡ Async & Fast — Powered by tokio for asynchronous, non-blocking operations.
• 🎨 Colorized CLI Experience — Beautiful terminal output with colorized for clear and intuitive interaction.
• 💾 Next-Gen Database — Uses SurrealDB for flexible and secure data storage.
• 🧰 Robust Error Handling — Managed with anyhow for clear, user-friendly error messages.
• 📦 Serialization Made Simple — Data structures powered by serde for seamless serialization and deserialization.
