The package management functions of the Security Support Provider Interface (SSPI) enumerate and query the attributes of the security packages of a security provider.
A security provider is a dynamic-link library that implements the SSPI to make one or more security packages available to applications. Each security package provides the necessary mapping between the SSPI and the actual security model, such as Kerberos or Microsoft LAN Manager.
The following functions provide management services for these packages.
| Function | Description |
|---|---|
| EnumerateSecurityPackages | List available security packages and their capabilities. |
| InitSecurityInterface | Retrieve a pointer to a security provider dispatch table. |
| QuerySecurityPackageInfo | Query an individual security package for its capabilites. |
