The SpVerifySignature function is the dispatch function for the VerifySignature function of the Security Support Provider Interface.
A handle to the security context used to sign the message.
Pointer to a SecBufferDesc structure containing the message to verify.
Sequence number to assign to the message. Sequence numbers are optional and are used as protection against loss and insertion of messages. A value of zero indicates that sequence numbers are not in use.
Pointer to package-specific flags that indicate the quality of protection.
If the function succeeds, return STATUS_SUCCESS.
If the function fails, return an NTSTATUS code that indicates the reason it failed. The following table lists a common reason for failure and the error code that the function should return.

The signature verified by the SpVerifySignature function is created by the SpMakeSignature function, used by a message sender.
SSP/APs must implement the SpVerifySignature function; however, the actual name given to the implementation is up to the developer.
A pointer to the SpVerifySignature function is available in the SECPKG_USER_FUNCTION_TABLE structure received from the SpUserModeInitialize function.
