LocalWeb Crypto (AES‑GCM + PBKDF2)
AES Encrypt / Decrypt — Local Text Encryption
Encrypt and decrypt text using AES-256-GCM with a passphrase. All processing happens locally in your browser.
Mode
Encrypt creates a Base64 payload. Decrypt reverses it with the same passphrase.
Input
Paste plaintext (or upload a .txt file).
Output
Encrypted Base64 payload.
Passphrase
Use a long passphrase. We can’t recover it if you forget it.
