X509ChainStatusFlags Enum

Definition

Defines the status of an X509 chain.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Fields

CtlNotSignatureValid 262144

Specifies that the certificate trust list (CTL) contains an invalid signature.

CtlNotTimeValid 131072

Specifies that the certificate trust list (CTL) is not valid because of an invalid time value, such as one that indicates that the CTL has expired.

CtlNotValidForUsage 524288

Specifies that the certificate trust list (CTL) is not valid for this use.

Cyclic 128

Specifies that the X509 chain could not be built.

ExplicitDistrust 67108864

Specifies that the certificate is explicitly distrusted.

HasExcludedNameConstraint 32768

Specifies that the X509 chain is invalid because a certificate has excluded a name constraint.

HasNotDefinedNameConstraint 8192

Specifies that the certificate has an undefined name constraint.

HasNotPermittedNameConstraint 16384

Specifies that the certificate has an impermissible name constraint.

HasNotSupportedCriticalExtension 134217728

Specifies that the certificate does not support a critical extension.

HasNotSupportedNameConstraint 4096

Specifies that the certificate does not have a supported name constraint or has a name constraint that is unsupported.

HasWeakSignature 1048576

Specifies that the certificate has not been strong signed. Typically, this indicates that the MD2 or MD5 hashing algorithms were used to create a hash of the certificate.

InvalidBasicConstraints 1024

Specifies that the X509 chain is invalid due to invalid basic constraints.

InvalidExtension 256

Specifies that the X509 chain is invalid due to an invalid extension.

InvalidNameConstraints 2048

Specifies that the X509 chain is invalid due to invalid name constraints.

InvalidPolicyConstraints 512

Specifies that the X509 chain is invalid due to invalid policy constraints.

NoError 0

Specifies that the X509 chain has no errors.

NoIssuanceChainPolicy 33554432

Specifies that there is no certificate policy extension in the certificate. This error would occur if a group policy has specified that all certificates must have a certificate policy.

NotSignatureValid 8

Specifies that the X509 chain is invalid due to an invalid certificate signature.

NotTimeNested 2

Deprecated. Specifies that the CA (certificate authority) certificate and the issued certificate have validity periods that are not nested. For example, the CA cert can be valid from January 1 to December 1 and the issued certificate from January 2 to December 2, which would mean the validity periods are not nested.

NotTimeValid 1

Specifies that the X509 chain is not valid due to an invalid time value, such as a value that indicates an expired certificate.

NotValidForUsage 16

Specifies that the key usage is not valid.

OfflineRevocation 16777216

Specifies that the online certificate revocation list (CRL) the X509 chain relies on is currently offline.

PartialChain 65536

Specifies that the X509 chain could not be built up to the root certificate.

RevocationStatusUnknown 64

Specifies that it is not possible to determine whether the certificate has been revoked. This can be due to the certificate revocation list (CRL) being offline or unavailable.

Revoked 4

Specifies that the X509 chain is invalid due to a revoked certificate.

UntrustedRoot 32

Specifies that the X509 chain is invalid due to an untrusted root certificate.

Remarks

This enumeration is used in conjunction with the X509ChainStatus structure and the ChainStatus property.

The flags ExplicitDistrust, HasNotSupportedCriticalExtension and HasWeakSignature were introduced with the .NET Framework 4.6.1.
