Encrypt AES

MODEX

About this app

Encrypt AES gives you private, time-limited notes protected with modern
cryptography.

Built for people who want control, not accounts.

Why Encrypt AES
• AES-256-GCM encryption with integrity protection
• Password-based key derivation (PBKDF2-SHA256)
• Random salt and IV for every encrypted bundle
• Secure bundle format with versioning for compatibility
• Time-limited notes: No expiry, 5 min, 10 min, or 30 min
• Trusted expiry checks using network time sync
• Fully local encryption and decryption on your device
• No account system, no cloud storage, no message syncing

How it works

1. Create a secure bundle with optional title and tag, required message, and
timestamps.
2. Encrypt into a compact Base64 payload.
3. Share or store the encrypted bundle.
4. Decrypt using the same secret key.

Expiry protection
• If a message is expired, plaintext is never shown.
• Expiry checks are validated against trusted time to reduce clock tampering.

Privacy and security notes
• Secrets and plaintext are never sent to app servers.
• Decryption errors are intentionally generic to avoid leaking sensitive
details.
• Clipboard copy is available for encrypted bundles only.

Encrypt AES is built for private communication where timing and control
matter.
