About Random Bytes

This tool uses the Web Crypto API's crypto.getRandomValues() to generate cryptographically secure random bytes. These are suitable for security-sensitive applications.

Common Use Cases

  • Generate encryption keys and initialization vectors (IVs)
  • Create session tokens and CSRF tokens
  • Generate API keys and secrets
  • Create random salts for password hashing
  • Generate nonces for cryptographic protocols

Security: The generated bytes use a cryptographically strong random number generator suitable for security-sensitive applications.
