Class Hierarchy

• dkim.canonicalization.CanonicalizationPolicy

  • logging.Handler: Handler instances dispatch logging events to specific destinations.
    • dkim.util.NullHandler
• dkim.canonicalization.Relaxed: Class that represents the "relaxed" canonicalization algorithm.
• dkim.canonicalization.Simple: Class that represents the "simple" canonicalization algorithm.
• object: The most base type
  • exceptions.BaseException: Common base class for all exceptions
    • exceptions.Exception: Common base class for all non-exit exceptions.
      • dkim.asn1.ASN1FormatError
