Messages will be output one per line. Each line will start with a single capital letter, a colon, and a space. The letters indicate the type of message:
- B: Bug. Your certificate has a feature not handled by certlint.
- I: Information. These are purely informational; no action is needed.
- N: Notice. These are items known to cause issues with one or more implementations of certificate processing but are not errors according to the standard.
- W: Warning. These are issues where a standard recommends differently but the standard uses terms such as "SHOULD" or "MAY".
- E: Error. These are issues where the certificate is not compliant with the standard.
- F: Fatal Error. These errors are fatal to the checks and prevent most further checks from being executed. These are extremely bad errors.
