(Delphi ActiveX) Belgium eHealth Platform - checkAccessControl

See more Belgian eHealth Platform Examples

Demonstrates the checkAccessControl operation of PlatformIntegrationConsumerTest, which requires an X.509 certificate and signature. This tests the validity of your certificate and signature.
