Text encrypt / decrypt
Encrypt and decrypt text with a password, using AES-256.
AES-256-GCM with a PBKDF2 key from your password. Encrypted in your browser — the password is never stored or sent. Lose the password and the message is unrecoverable.
How it works
Enter your text
Type or paste the message you want to protect.
Set a password
Choose a strong password — it is the only way to decrypt the result.
Encrypt or decrypt
Copy the encrypted output to share, or paste ciphertext and your password to read it back.
Why use Text encrypt / decrypt
Strong, standard encryption
Text is protected with AES-256 via the browser’s Web Crypto API, with your password stretched into a key.
Only you hold the key
Encryption and decryption happen locally and the password is never sent anywhere, so only someone with it can read the message.
Shareable ciphertext
The output is plain text you can paste into a message or note; the recipient decrypts it with the same password.
