Encryption Key Generator

Generate cryptographically secure random keys for encryption, API authentication, tokens, and more.

Key Configuration

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.
