AES Encrypt / Decrypt — Encrypt text with a password and paste the result into an email, a chat, or a file. The recipient decrypts with the same password.
Encryption and decryption run in your browser. The password and the message never leave the page.

Apa itu AES Encrypt / Decrypt?
Encrypt text with a password and paste the result into an email, a chat, or a file. The recipient decrypts with the same password.
Encryption is AES-256-GCM (authenticated, so tampering is detected). Keys are derived from the password with PBKDF2-SHA256 and 250,000 iterations. Everything runs in your browser — the password and the message never reach a server.
Cara menggunakannya
-
Choose encrypt or decrypt
Two modes. Same password field, different input and output sides.
-
Pick a strong password
A random 20-character string is the right pick for sensitive data. Use the password generator if you do not have one.
-
Encrypt or decrypt
The result is a portable text envelope you can paste anywhere.
Contoh
Send a one-time secret in an email
Encrypt a password, a token, or a short message with a passphrase. Send the ciphertext in an email, share the passphrase by phone. The recipient pastes the ciphertext, enters the passphrase, and gets the original.
Plaintext: "Meeting at 3pm, use the back door" Password: "blue-river-42"
Hasil: A v1:base64... envelope that decrypts only with "blue-river-42".
Encrypt a note for yourself
Store a ciphertext in a note-taking app, a password manager, or a file. Decrypt it from any device with the password. Useful for API keys, recovery codes, or anything you do not want in plaintext.
Plaintext: an API key Password: a strong password you remember
Hasil: The ciphertext is safe to store. Only the password unlocks it.
