Authentication Services Functions (Compact 2013)

3/28/2014

This section defines the authentication services functions. Among these are the SSPI callback functions, for example, AcceptSecurityContext. A SecurityFunctionTable structure contains pointers to these callback functions.

Note

An SSPI callback function should be called by dereferencing the field of the same name in the SecurityFunctionTable structure retrieved by a call to the InitSecurityInterface function. It is not recommended to call the callback functions directly.

Programming element	Description
AcceptSecurityContext	This function enables the server part of a transport application to establish a security context between the server and a remote client.
AcquireCredentialsHandle	This function allows applications to acquire a handle to preexisting credentials associated with the user on whose behalf the call is made.
ApplyControlToken	This function provides a way to apply a control token to a security context.
CompleteAuthToken	This function completes an authentication token.
DecryptMessage	This function decrypts a message.
DeleteSecurityContext	This function deletes local data structures associated with the specified security context.
EncryptMessage	This function encrypts a message to help provide privacy.
EnumerateSecurityPackages	This function retrieves an array of SecPkgInfo structures that describe the security packages available to the client.
FreeContextBuffer	This function enables callers of security provider functions to free a memory buffer allocated by the security provider.
FreeCredentialsHandle	This function notifies the security system that credentials are no longer required.
InitializeSecurityContext	This function initiates the outbound security context from a credential handle.
InitSecurityInterface	This function returns a pointer to a Security Service Provider Interface (SSPI) dispatch table.
InternetCanonicalizeUrl	This function converts a URL to a canonical form, including the conversion of unsafe characters into escape sequences.
MakeSignature	This function generates a cryptographic checksum of the message and includes sequencing information to prevent message loss or insertion.
NTLMAddGroup	This function adds a new NTLM group.
NTLMAddUserToGroup	This function adds an existing user to an existing NTLM group.
NTLMDeleteUser	This function deletes a user name from the local database.
NTLMEnumGroups	This function enumerates an NTLM group.
NTLMEnumUser	This function enumerates a user in a local database.
NTLMGetGroupList	This function gets a list of groups to which a user belongs.
NTLMGetUserList	This function gets the list of users belonging to an NTLM group.
NTLMRemoveGroup	This function removes an existing NTLM group.
NTLMRemoveUserFromGroup	This function removes a user from an NTLM group.
NTLMSetUserInfo	This function adds user information to the local database.
QueryContextAttributes	This function enables a transport application to query a security package for certain attributes of a security context.
QueryCredentialsAttributes	This function retrieves the attributes of a credential, such as the name associated with the credential.
QuerySecurityPackageInfo	This function retrieves information about a specified security package.
SealMessage	This function seals a message.
UnsealMessage	This function unseals a message.
VerifySignature	This function verifies the signature of a message at the other end.
