नि:शुल्क Text Encryption
Encrypt and decrypt text with a password using strong AES-256-GCM. The password never leaves your browser. Share secrets safely.
Strong, standard encryption: AES-256-GCM with a key derived from your password via PBKDF2 (250,000 iterations, SHA-256). Each message uses a fresh random salt and IV.
The password is never stored or sent anywhere — everything runs in your browser. If you lose the password, the message cannot be recovered. Share the encrypted text and the password through separate channels.

यो कसरी काम गर्छ
Send a secret over an insecure channel (email, chat) by encrypting it with a password only you and the recipient know. This uses the same strong, standard cryptography as password managers — running entirely in your browser.
- 1You enter text and a passwordNothing is uploaded; the password is never stored or transmitted.
- 2A key is derived from your passwordPBKDF2 stretches your password with 250,000 SHA-256 iterations and a fresh random salt, making brute-force attacks slow.
- 3The text is encrypted with AES-256-GCMA random IV is used each time, and GCM adds an authentication tag so tampering (or a wrong password) is detected on decryption.
- 4You share the encrypted textSend the base64 result over any channel, and the password separately. The recipient pastes both here to decrypt.
All cryptography runs locally with the browser's native Web Crypto. The plaintext and password never leave your device. If the password is lost, the message is unrecoverable — that's the point.
