Text Encrypt & Decrypt
Protect private notes and messages with password-based AES-256 encryption that runs fully in your browser. Type your text, set a password and click Encrypt; paste the code and enter the same password to read it back.
Warning: If you forget the password, the text can never be recovered. Nothing is sent to any server — encryption happens only on your device.
How to use
- To encrypt: type your text, set a password, click Encrypt, and copy the code. Share the code anywhere — only the password can open it.
- To decrypt: paste the code, type the same password, click Decrypt.
- Keep the password safe separately — without it, recovery is impossible by design.
Good to know
- Use a long passphrase you can remember — a forgotten password cannot be recovered, ever.
- Send the encrypted code and the password through different channels (for example message plus a phone call).
- Short passwords are always the weak link, even with strong AES-256 encryption.
How it works: PBKDF2 (150,000 rounds) turns your password into a key, then AES-GCM 256 encrypts the text. The random salt and IV are packed with the result in Base64.
