Key Types Explained

AES Keys

AES-128: 128-bit (16-byte) key for AES encryption
AES-256: 256-bit (32-byte) key for stronger AES encryption
Most commonly used symmetric encryption standard

API Keys

Custom-length keys for API authentication
Commonly 32-64 bytes
Used for authenticating API requests

Random Tokens

General-purpose random tokens
Useful for session IDs, CSRF tokens
Cryptographically secure randomness

Strong Passwords

Random passwords with letters, numbers, symbols
Configurable length and character sets
Suitable for account passwords

Security Note: All keys are generated using your browser's cryptographically secure random number generator (crypto.getRandomValues). Keys are never sent to any server.
