AES-GCM Encryption
Encrypt and decrypt text with AES-256-GCM. PBKDF2 key derivation (100,000 iterations). Everything happens in your browser.
Algorithm: AES-256-GCM (authenticated encryption)
Key derivation: PBKDF2 with SHA-256, 16-byte random salt, 100,000 iterations
IV: 12 random bytes generated for each encryption
Output format: base64(salt || iv || ciphertext)
