Installing a Security Provider

Security providers are installed by updating a value in the registry, located as follows:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control
    SecurityProviders
        SecurityProviders = REG_SZ provider1.dll, provider2.dll,...
 

There can be multiple providers in a single DLL. PROVIDER1.DLL can contain two security "packages"; for example, "Protocol 1" and "Protocol 2."
