OBSOLETE: It is strongly recommended to use the OpcLabs.EasyOpc.UA.Discovery.IUAReadOnlyApplicationElement.ApplicationName and other such properties instead.
The subject name of the client application certificate. When empty, the component will make a subject name automatically, and it will be the same as the application name.
'Declaration<NotNullAttribute()> ReadOnly Property InstanceCertificateSubject As String
'UsageDim instance As IUAReadOnlyApplicationManifest Dim value As String value = instance.InstanceCertificateSubject
[NotNull()] string InstanceCertificateSubject {get;}
The subject name is used when looking for the certificate.
The automatically created name is based on the description (title) of the application assembly.
When the certificate subject differs from the application name, problems such as multiple creation of instance certificates may arise. WE THEREFORE STRONGLY RECOMMEND THAT YOU KEEP THIS PARAMETER EMPTY.
In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.
This is the distinguished name of an X509 certificate according to the Abstract Syntax Notation One (ASN.1) syntax.
The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension. Where it is non-empty, the subject field MUST contain an X.500 distinguished name (DN). Name is defined by the following ASN.1 structures:
Name ::= CHOICE {RDNSequence }
RDNSequence ::= SEQUENCE OF RelativeDistinguishedName
RelativeDistinguishedName ::= SET OF AttributeTypeAndValue
AttributeTypeAndValue ::= SEQUENCE {type AttributeType, value AttributeValue }
AttributeType ::= OBJECT IDENTIFIER
AttributeValue ::= ANY DEFINED BY AttributeType
DirectoryString ::= CHOICE {
teletexString TeletexString (SIZE (1..MAX)),
printableString PrintableString (SIZE (1..MAX)),
universalString UniversalString (SIZE (1..MAX)),
utf8String UTF8String (SIZE (1..MAX)),
bmpString BMPString (SIZE (1..MAX)) }
The Name describes a hierarchical name composed of attributes, such as country name, and corresponding values, such as US. The type of the component AttributeValue is determined by the AttributeType; in general it will be a DirectoryString.
String X.500 AttributeType:
This notation is designed to be convenient for common forms of name. This section gives a few examples of distinguished names written using this notation. First is a name containing three relative distinguished names (RDNs): CN=Steve Kille,O=Isode Limited,C=GB
