Expand description

An error that occurs during certificate validation or name validation.

Variants

BadDER

The encoding of some ASN.1 DER-encoded item is invalid.

BadDERTime

The encoding of an ASN.1 DER-encoded time is invalid.

CAUsedAsEndEntity

A CA certificate is veing used as an end-entity certificate.

CertExpired

The certificate is expired; i.e. the time it is being validated for is later than the certificate’s notAfter time.

CertNotValidForName

The certificate is not valid for the name it is being validated for.

CertNotValidYet

The certificate is not valid yet; i.e. the time it is being validated for is earlier than the certificate’s notBefore time.

EndEntityUsedAsCA

An end-entity certificate is being used as a CA certificate.

ExtensionValueInvalid

An X.509 extension is invalid.

InvalidCertValidity

The certificate validity period (notBefore, notAfter) is invalid; e.g. the notAfter time is earlier than the notBefore time.

InvalidSignatureForPublicKey

The signature is invalid for the given public key.

NameConstraintViolation

The certificate violates one or more name constraints.

PathLenConstraintViolated

The certificate violates one or more path length constraints.

SignatureAlgorithmMismatch

The algorithm in the TBSCertificate “signature” field of a certificate does not match the algorithm in the signature of the certificate.

RequiredEKUNotFound

The certificate is not valid for the Extended Key Usage for which it is being validated.

UnknownIssuer

A valid issuer for the certificate could not be found.

UnsupportedCertVersion

The certificate is not a v3 X.509 certificate.

UnsupportedCriticalExtension

The certificate contains an unsupported critical extension.

UnsupportedSignatureAlgorithmForPublicKey

The signature’s algorithm does not match the algorithm of the public key it is being validated for. This may be because the public key algorithm’s OID isn’t recognized (e.g. DSA), or the public key algorithm’s parameters don’t match the supported parameters for that algorithm (e.g. ECC keys for unsupported curves), or the public key algorithm and the signature algorithm simply don’t match (e.g. verifying an RSA signature with an ECC public key).

UnsupportedSignatureAlgorithm

The signature algorithm for a signature is not in the set of supported signature algorithms given.
