SSPI Functions and Structures (Windows Embedded CE 6.0)

1/6/2010

The following table shows the SSPI functions that are supported by Windows Embedded CE.

Function	Description
AcceptSecurityContext	Establishes an inbound security context between the server and a remote client.
AcquireCredentialsHandle	Enables an application to acquire a handle to existing user credentials. This function also provides a way for applications to supply credential data.
ApplyControlToken	Provides a way to apply a control token to a security context.
DeleteSecurityContext	Deletes local data structures associated with the specified security context.
EnumerateSecurityPackages	Returns an array of SecPkgInfo structures that describe the security packages available to the client.
FreeContextBuffer	Enables callers of security provider functions to free a memory buffer allocated by the security provider.
FreeCredentialsHandle	Notifies the security system that the credentials are no longer needed.
InitSecurityInterface	Returns a pointer to an SSPI dispatch table.
InitializeSecurityContext	Initiates the outbound security context from a credential handle. This function establishes a security context between the client application and a remote peer.
MakeSignature	Generates a cryptographic checksum of the message and includes sequencing data to prevent message loss or insertion.
QueryContextAttributes	Enables a transport application to query a security package for certain security context attributes.
QueryCredentialsAttributes	Retrieves the credential attributes.
QuerySecurityPackageInfo	Retrieves data about a specified security package.
VerifySignature	Verifies the signature of a peer client message.

The following table shows the SSPI structures supported by Windows Embedded CE.

Structure	Description
SecBuffer	Describes a buffer that is allocated by a transport application to pass to a security package.
SecBufferDesc	Describes an array of SecBuffer structures to pass from a transport application to a security package.
SecPkgContext_Authority	Contains the name of the authenticating authority, if one is available.
SecPkgContext_KeyInfo	Contains data about the keys used in a security context.
SecPkgContext_Lifespan	Indicates the life span of a security context.
SecPkgContext_Names	Indicates the user name associated with a security context.
SecPkgContext_Sizes	Indicates the size of important structures used in the message support functions.
SecPkgContext_StreamSizes	Indicates the size of the various stream objects that are used with the message support functions.
SecPkgCredentials_Names	Indicates the name of the user associated with a credential.
SecPkgInfo	Provides general security package data, such as the name and capabilities of the package.
SecurityFunctionTable	Contains pointers to the callback functions defined in the Sspi.h file.
