👋 New here? Type your message → set a password → press Encrypt. That's it — decrypting works the same way in reverse.
Your message ?Type or paste the message you want to lock with a password.
You can also drag & drop a .txt file here 0 / 20,000 characters
Scan a QR code ?Point your camera at a QR code someone sent you, or upload a screenshot/photo of one — the encrypted text will be read straight into the box above.

Camera access needs your permission, and works best on https:// pages.

Password ?Anyone who wants to unlock this text will need this exact password.
Confirm password
Password strength: —
Cipher: AES-256-GCM (authenticated) · Key derived with PBKDF2-SHA256 (60,000 iterations) using your browser's native encryption engine — fast, and far stronger against brute-force than a single hashing round. ?This is a real security upgrade, not just a label: deriving the encryption key takes real computational work, which makes large-scale password-guessing attacks dramatically slower.
Second password
Both passwords will be needed to unlock this message. Store them separately for maximum security.
Self-destruct ?After this time, the message can no longer be decrypted — even with the right password.
Password hint (optional) ?Shown to anyone with the encrypted text, before they enter a password. Never put the password itself here.
Overall protection: Basic Set a stronger password to improve this score.

Result
Cover image (optional)

Leave empty and we'll auto-generate a suitable image. PNG output only — JPEG, WhatsApp, and other apps that recompress images will destroy the hidden data, so share the downloaded PNG file directly.

Frequently asked questions

Can this decrypt any encrypted text?
It decrypts messages created with this tool. Text encrypted with other software uses other formats and will not open here.

The password is case sensitive and must match exactly. A message that was edited or cut when copying also fails to open.
Does decryption upload my message?
No. The message and password are used only inside your browser.
