X509ChainPolicy::VerificationTime Property

 

The time that the certificate was verified expressed in local time.

Namespace:   System.Security.Cryptography.X509Certificates
Assembly:  System (in System.dll)

public:
property DateTime VerificationTime {
	DateTime get();
	void set(DateTime value);
}

Property Value

Type: System::DateTime

A DateTime object.

This property returns a value indicating the time the certificate was validated, expressed in local time. This is important when validating signed messages, since the signature must have been valid at the time of signing, not at the time of validation.

The following example opens the current user's personal certificate store, allows the user to select a certificate, then writes certificate and certificate chain information to the console. The output depends on the certificate you select.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
Console::WriteLine( "Chain revocation flag: {0}", ch->ChainPolicy->RevocationFlag );
Console::WriteLine( "Chain revocation mode: {0}", ch->ChainPolicy->RevocationMode );
Console::WriteLine( "Chain verification flag: {0}", ch->ChainPolicy->VerificationFlags );
Console::WriteLine( "Chain verification time: {0}", ch->ChainPolicy->VerificationTime );
Console::WriteLine( "Chain status length: {0}", ch->ChainStatus->Length );
Console::WriteLine( "Chain application policy count: {0}", ch->ChainPolicy->ApplicationPolicy->Count );
Console::WriteLine( "Chain certificate policy count: {0} {1}", ch->ChainPolicy->CertificatePolicy->Count, Environment::NewLine );
