SecPkgInfo

The SecPkgInfo structure provides general information about a security package, such as its name and its capabilities.

typedef struct _SecPkgInfo {
      ULONG fCapabilities;  // capability of bit mask
      USHORT wVersion;      // version of driver
      USHORT wRPCID;        // identifier for RPC run time
      ULONG cbMaxToken;     // size of authentication token
      SEC_CHAR * Name;      // text name
      SEC_CHAR * Comment;   // comment
} SecPkgInfo, * PSecPkgInfo;   
 

Members

fCapabilities

A set of bit flags that describe the capabilities of the security package. This member can be a combination of the following flags.

Value	Meaning
SECPKG_FLAG_INTEGRITY	Verify that all messages exchanged have not been tampered with or exchanged out of sequence.
SECPKG_FLAG_PRIVACY	All messages are tamper proof and are not passed in cleartext. Reserved for future use.
SECPKG_FLAG_TOKEN_ONLY	The package is interested only in the security-token portion of messages, and will ignore any other buffers. This is a performance-related issue.
SECPKG_FLAG_DATAGRAM	Supports datagram-style authentication. For more information, see Context Semantics.
SECPKG_FLAG_CONNECTION	Supports connection-oriented style authentication. For more information, see Context Semantics.
SECPKG_FLAG_MULTI_REQUIRED	Multiple legs are required for authentication.
SECPKG_FLAG_CLIENT_ONLY	Server authentication support is not provided.
SECPKG_FLAG_EXTENDED_ERROR	Supports extended error handling. For more information, see Extended Error Information.
SECPKG_FLAG_IMPERSONATION	Supports Win32 impersonation in server contexts.
SECPKG_FLAG_ACCEPT_WIN32_NAME	Understands Win32 principal and target names.
SECPKG_FLAG_STREAM	Supports stream semantics. For more information, see Context Semantics.

wVersion

Specifies the version of the package protocol. Must be 1.

wRPCID

Specifies a DCE RPC identifier, if appropriate. If the package does not implement one of the DCE registered security systems, the reserved value SECPKG_ID_NONE is used.

cbMaxToken

Specifies the maximum size, in bytes, of the token.

Name

Pointer to a null-terminated string that contains the name of the security package.

Comment

Pointer to a null-terminated string. This can be any additional string passed back by the package.
