System 2.0.0.0 4.0.0.0 System.Enum System.Flags This enumeration is used in conjunction with the structure and the property. Defines the status of an X509 chain. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the certificate trust list (CTL) contains an invalid signature. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags 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. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the certificate trust list (CTL) is not valid for this use. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain could not be built. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid because a certificate has excluded a name constraint. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the certificate has an undefined name constraint. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the certificate has an impermissible name constraint. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the certificate does not have a supported name constraint or has a name constraint that is unsupported. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to invalid basic constraints. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to an invalid extension. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to invalid name constraints. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to invalid policy constraints. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain has no errors. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags 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. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to an invalid certificate signature. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags 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. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is not valid due to an invalid time value, such as a value that indicates an expired certificate. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the key usage is not valid. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the online certificate revocation list (CRL) the X509 chain relies on is currently offline. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain could not be built up to the root certificate. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags 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. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to a revoked certificate. Field 2.0.0.0 4.0.0.0 System.Security.Cryptography.X509Certificates.X509ChainStatusFlags Specifies that the X509 chain is invalid due to an untrusted root certificate.
