<cLocation>
A character string which selects the location of the certificate store. This can be either "user" or "machine". If no location is passed, the machine context is used as the default.

Description

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.
