Does this AES encryption tool upload my plaintext or password?

No. Encryption happens locally in your browser, so the plaintext, password, and payload remain on your device.

What encryption mode does the tool use?

It uses AES-GCM, which provides authenticated encryption. That means it protects the confidentiality of the plaintext and helps detect tampering with the encrypted payload.

Why does the encrypted output include salt and IV fields?

The salt is used during password-based key derivation and the IV is required by AES-GCM encryption. Both must be stored alongside the ciphertext so the message can be decrypted later with the same password.

Can I decrypt the payload without the original password?

No. The password is required to derive the same encryption key. Without it, the payload cannot be decrypted successfully.

Is this suitable for files too?

This tool is designed for text payloads. For files, use tools built for file encryption workflows or encrypt the file contents separately before transport.

AES Encrypt

Encrypt text locally with AES-GCM using a password-derived key, random salt, and self-contained JSON payload output. Perfect for private notes, shared secrets, and browser-side encryption workflows without server uploads.

AES-GCM Input & Settings

Encrypt plaintext into a self-contained AES-GCM JSON payload.

Plaintext

Characters: 0

Lines: 0

Bytes: 0

Password

How it works: This tool derives a 256-bit AES-GCM key from your password using PBKDF2 with SHA-256, a random salt, and 250,000 iterations. Encryption output is stored as JSON containing the algorithm, salt, IV, and ciphertext so you can decrypt it later with the same password.
