Loading the Security Support Provider DLL

To use SSPI with Microsoft® Windows NT®/Microsoft® Windows® 2000, both the client and server components of a transport application call the LoadLibrary function to load Secur32.dll, a security support provider (SSP). This SSP supports all security packages available on the system, including:

• Kerberos package
• NTLM package
• MSN package
• Negotiate and Negotiate2 packages

The Kerberos package is available only with Windows 2000 or later.

For code using LoadLibrary, see the InitPackage function in Using SSPI with a Windows Sockets Client or Using SSPI with a Windows Sockets Server.
