+/**

+  @par Protocol Description:

+  The EFI_BIS_PROTOCOL is used to check a digital signature of a data block against a digital

+  certificate for the purpose of an integrity and authorization check.

+

+  @param initialize

+  Initializes an application instance of the EFI_BIS protocol,

+  returning a handle for the application instance. Other functions in

+  the EFI_BIS protocol require a valid application instance

+  handle obtained from this function.

+  

+  @param Shutdown 

+  Ends the lifetime of an application instance of the EFI_BIS

+  protocol, invalidating its application instance handle. The

+  application instance handle may no longer be used in other

+  functions in the EFI_BIS protocol.

+

+  @param Free 

+  Frees memory structures allocated and returned by other

+  functions in the EFI_BIS protocol. 

+

+  @param GetBootObjectAuthorizationCertificate

+  Retrieves the current digital certificate (if any) used by the

+  EFI_BIS protocol as the source of authorization for verifying

+  boot objects and altering configuration parameters.

+

+  @param GetBootObjectAuthorizationCheckFlag

+  Retrieves the current setting of the authorization check flag that

+  indicates whether or not authorization checks are required for

+  boot objects.

+

+  @param GetBootObjectAuthorizationUpdateToken

+  Retrieves an uninterpreted token whose value gets included and

+  signed in a subsequent request to alter the configuration

+  parameters, to protect against attempts to replay such a request.

+

+  @param GetSignatureInfo 

+  Retrieves information about the digital signature algorithms

+  supported and the identity of the installed authorization

+  certificate, if any.

+

+  @param UpdateBootObjectAuthorization

+  Requests that the configuration parameters be altered by

+  installing or removing an authorization certificate or changing the

+  setting of the check flag. 

+

+  @param VerifyBootObject

+  Verifies a boot object according to the supplied digital signature

+  and the current authorization certificate and check flag setting.

+

+  @param VerifyObjectWithCredential

+  Verifies a data object according to a supplied digital signature

+  and a supplied digital certificate.
