AES Cipher
AES-128/192/256 encryption in GCM/CBC mode with .NET compatibility
Password mode uses PBKDF2 derivation. Manual mode uses direct key/IV.
Higher = more secure but slower (10,000 - 1,000,000)
GCM provides authentication. CBC is classic mode compatible with most systems.
Hex: standard format. UTF-8: for .NET Encoding.UTF8.GetBytes() compatibility.
Select key strength: AES-128 (fast), AES-192 (balanced), AES-256 (maximum security)
Any even number of hex characters (e.g., 64 for AES-256)
Any even number of hex characters (depends on cipher mode)
Privacy & Security: All encryption happens locally in your browser. Your data and passwords never leave your device.
Auto mode extracts key from password. Manual mode uses provided key/IV.
