Questions tagged [sspi]

Use for questions having to do with the Security Support Provider Interface (SSPI) API.

It is implemented as a a dynamic-link library (DLL) supplied with the operating system. SSPI is the means by which the operating system loads SSPs (Security Support Providers), such as Kerberos and NTLM, when the system boots. The SSPI is the implementation of the Generic Security Service API () in Windows.
