Function IsCertificateAvailable() Professional
Checks whether a certificate is available on the computer.
IsCertificateAvailable( [<cSubject>] [, <cStoreName>] [, <cLocation>] )
The logical value true (.T.), if the specified certificate is available on the computer. Otherwise, the value false (.F.) is returned.
The function IsCertificateAvailable() checks whether a certain certificate is installed in the specified certificate store of the computer. The function can be used, for example, to check whether a certain SSL certificate is available prior to establishing an SSL connection via a HttpEndPoint() or a socket. See the function CertificateSelect() and the methods HttpEndPoint:setCertificate() and HttpClient:setCertificate() for further information.
The certificate must be specified via the subject name, the name of the certificate store, and the location the store resides in. A certificate store can exist either in the user or in the machine context. The user context contains certificates for the current user, whereas certificates in the machine context are valid for the local machine.
