# Enum Class PKIXReason

java.lang.Object
java.lang.Enum<PKIXReason>
java.security.cert.PKIXReason

All Implemented Interfaces:
  `Serializable, Comparable<PKIXReason>, Constable, CertPathValidatorException.Reason`

public enum PKIXReason extends Enum<PKIXReason> implements CertPathValidatorException.Reason
The `PKIXReason` enumerates the potential PKIX-specific reasons that an X.509 certification path may be invalid according to the PKIX (RFC 5280) standard. These reasons are in addition to those of the `CertPathValidatorException.BasicReason` enumeration.
