Encrypt & Decrypt Text
Military-grade AES-256-GCM encryption. Processed locally in your browser. Large payloads can be attached as TXT files instead of pasted.
True Zero-Knowledge. Encryption keys are derived locally. Nothing is transmitted to the server except this static page. Close the tab and everything vanishes, even from your local memory. Clipboard actions may be limited outside the secure context, but file attach and file download still work offline and when hosted.
