AES Encrypt & Decrypt
Encrypt and decrypt text using AES-256-GCM with PBKDF2 key derivation — entirely in your browser.
Everything runs in your browser. No data is ever sent to any server.
Use a long, unique passphrase. It is derived into a 256-bit key using PBKDF2 (100k iterations, SHA-256).

How It Works
AES-256-GCM
Military-grade authenticated encryption. GCM mode detects any tampering with the ciphertext, so you know decryption results are trustworthy.
PBKDF2 Key Derivation
Your passphrase is never used directly. PBKDF2 with 100,000 iterations and SHA-256 transforms it into a strong 256-bit encryption key with a unique random salt.
Browser-Only
All cryptographic operations run via the browser's native Web Crypto API. Zero server calls — your data never leaves your device.
