A semantic refusal, never a substitute for resource or decoding failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IssuerForm

Issuer is not V2 with exactly one nonempty directoryName and no other forms.

Serial

Serial is zero, negative, or exceeds the twenty encoded octet limit.

Validity

The inclusive validity interval is reversed.

HolderIssuer

A holder baseCertificateID has an out-of-profile issuer name.

NameForm

RFC5755 §4.2 excludes X.400, EDI party and registered-ID name forms.

ObjectDigest

Optional objectDigestInfo names a forbidden object/type combination.

Criticality

Criticality contradicts the extension’s profile.

UnknownCritical

An unrecognized critical extension cannot be accepted by this profile.

AuditIdentity

Audit identity is outside the one-through-twenty octet range.

TargetCertificate

A forbidden targetCert alternative was written.

AuthorityKeyIdentifier

The issuer key identifier required by the PKIX profile is absent.

OcspLocation

An OCSP access location is not an HTTP URL.

DistributionPoint

CRL distribution points do not have the single fullName/profile form.

RevocationConflict

NoRevAvail contradicts a written OCSP/CRL revocation pointer.

HolderAbsent

Explicitly selected Holder alternative is absent.

HolderCertificate

Supplied certificate’s issuer or serial does not match the base identity.

HolderName

None of the written entity names identifies the supplied certificate.

HolderUniqueId

A present holder issuerUID is absent/different in the supplied PKC.

AuthorityName

AC issuer DN does not identify the supplied authority certificate.

AuthorityUniqueId

AC issuer UID does not agree with the authority’s subject UID.

AuthorityIsCa

An AC authority cannot also be a certificate authority.

AuthorityUsage

Present keyUsage permits neither digitalSignature nor contentCommitment.

EmptyPath

A supplied AA path is empty.

MissingControls

A certificate below the explicitly selected AA CA lacks AAControls.

ControlDistance

AAControls pathLenConstraint is smaller than the actual distance.
