Creating Custom Security Packages

SSP Security Packages

If a custom security support provider (SSP) security package will be used exclusively for client/server security support it can implement the Microsoft Security Support Provider Interface.

The SampSSP sample shipped with the Platform Software Development Kit (SDK) contains a sample SSP security package implementation.

SSP/AP Security Packages

Custom security support provider/authentication packages (SSP/APs) contain security packages that function as authentication packages (APs) and security support providers (SSPs). These packages implement separate APIs to support each role.

Because it functions as an AP, a custom SSP/AP security package must provide implementations for all of the Functions Implemented by Authentication Packages.

To provide integrated security support, a custom SSP/AP security package must provide implementations for the Functions implemented by SSP/APs. LSA Functions Called by SSP/APs describes the support functions available to the SSP/AP developers that want to interact with the LSA.

SSP/AP security packages, in order to perform as both an AP and an SSP, may execute as part of the operating system and as part of a user application. These two modes of execution are known as LSA mode and user mode, respectively. For details about custom security packages in LSA mode see LSA Mode Initialization. For details about user mode, see User Mode Initialization.

If a custom SSP/AP security package offers services for client/server applications it should provide implementations for the functions described in Functions Implemented by User-mode SSP/APs. LSA Functions Called By User-mode SSP/APs describes the support functions available to an SSP/AP executing in a client or server process.

For information about registering an SSP/AP DLL, see Registering SSP/AP DLLs.
