Common use cases

  • ✓ API keys & secrets: 32–64 hex or alphanumeric characters is the standard for most API authentication schemes
  • ✓ Session tokens: 32+ alphanumeric characters provide enough entropy to make guessing infeasible
  • ✓ Database row IDs: UUID v4 provides collision-resistant identifiers without sequential exposure
  • ✓ CSRF tokens: 32-byte hex strings are commonly used as one-time CSRF protection values
  • ✓ Test data: Random alphanumeric strings make realistic-looking mock user IDs, order numbers, and reference codes
  • ✓ Encryption keys: 32-byte (64 hex char) strings represent 256-bit keys for AES-256
