Secure Text Encryptor
Security Tips:
- Passphrases are processed locally. Your data never leaves your device.
- Important: Send the ciphertext and the passphrase through different channels (e.g., email for ciphertext, signal/phone for passphrase).
- Use a long passphrase consisting of several random words for better security.
- This tool is a single-file application. You can save it and use it offline.
