  • Check: entropy, input handling, output format and threat model.
  • Limitation: a generator or checker is not a substitute for secure storage and review.

Common mistakes

  • Assuming the output is correct because the operation completed. Instead, inspect entropy, input handling, output format and threat model.
  • Using production or confidential material as the first test. Use a sample value created specifically for testing, never a real secret instead.
