CipherVault – Lightweight Browser-Based Encryption Tool

I’m excited to share CipherVault, a project by PXL – Programming eXperience Lab! It’s a lightweight, client-side tool for secure message encryption and decryption, built entirely with HTML, CSS, and Vanilla JS.

🔒 Key Features:

Encrypt and decrypt messages directly in the browser using AES-GCM 256-bit.

Password-based key derivation with PBKDF2 + 500,000 iterations.

Randomized salt & IV for each message.

Automatic field clearing and strong password enforcement.

Modern, responsive UI with optional retro-neon “Matrix-style” animations.

Base64 output for easy sharing.

💻 Why it stands out:

Runs entirely client-side, so sensitive data never leaves your device.

Combines strong cryptography, security-conscious UX, and a visually appealing interface.

Compared to other lightweight web encryptors, it enforces password strength, memory hygiene, and automatic clearing.

⚠️ Limitations:

Works best on modern browsers (uses Crypto API).

Password strength is critical—weak passwords reduce security.

Not intended for very large files or messages.

🚀 Future Plans:

Multi-file encryption support.

Passphrase hints without weakening security.

Integration with WebAssembly for faster crypto.

Export/import encrypted messages as .pxl files.

CipherVault is about privacy, security, and simplicity, with a bit of flair for those who love a retro-neon aesthetic. Feedback and contributions are welcome!
