Detailed Description

Validates certificates.

Constructor & Destructor Documentation

UnifiedAutomation.UaBase.CertificateValidator.CertificateValidator

(

ApplicationInstance

application

)

The default constructor.

Member Function Documentation

X509CertificateValidator UnifiedAutomation.UaBase.CertificateValidator.GetChannelValidator

(

)

Returns an object that can be used with WCF channel.

bool UnifiedAutomation.UaBase.CertificateValidator.GetIssuers	(	ICertificate	certificate,
		List< ICertificate >	issuers,
		ICertificate[]	chain,
		int	chainIndex
	)

Returns the issuers for the certificate.

virtual void UnifiedAutomation.UaBase.CertificateValidator.InternalValidate ( ICertificate[]  certificates, bool  mustValidateChain  )

protectedvirtual

Throws an exception if validation fails.

Parameters

certificates	The certificates.
mustValidateChain	if set to true the all certificates in the chain must be available and valid.

Exceptions

StatusException

If certificate cannot be accepted

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate ( ICertificate  certificate )

virtual

Validates a certificate.

Parameters

certificate

The certificate to validate.

Each UA application may have a list of trusted certificates that is different from all other UA applications that may be running on the same machine. As a result, the certificate validator cannot rely completely on the Windows certificate store and user or machine specific CTLs (certificate trust lists). The validator constructs the trust chain for the certificate and follows the chain until it finds a certification that is in the application trust list. Non-fatal trust chain errors (i.e. certificate expired) are ignored if the certificate is in the application trust list. If no certificate in the chain is trusted then the validator will still accept the certification if there are no trust chain errors. The validator may be configured to ignore the application trust list and/or trust chain.

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate ( ICertificate  certificate, ICertificate[]  chain, bool  mustValidateChain  )

virtual

Validates the specified certificate.

Parameters

certificate	The certificate.
chain	The chain.
mustValidateChain	if set to true then all certificates in the chain must be available and valid.

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate ( ICertificate[]  certificates, bool  mustValidateChain  )

virtual

Validates a certificate.

Parameters

certificates	The certificate chain. Must start with the certificate to validate.
mustValidateChain	if set to true then all certificates in the chain must be available and valid.
