Syntax

typedef struct _SecPkgInfo {
  ULONG fCapabilities;
  USHORT wVersion;
  USHORT wRPCID;
  ULONG cbMaxToken;
  SEC_CHAR SEC_FAR* Name;
  SEC_CHAR SEC_FAR* Comment;
} SecPkgInfo, SEC_FAR *PSecPkgInfo;

Members

  • fCapabilities
    Set of bit flags that describe the capabilities of the security package, which can be a combination of the flags shown in the following table.

    Flag

    Description

    SECPKG_FLAG_INTEGRITY

    Verifies that all messages exchanged have not been tampered with or exchanged out of sequence.

    SECPKG_FLAG_PRIVACY

    All messages are tamperproof and are not passed in clear text. Reserved.

    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.

    SECPKG_FLAG_CONNECTION

    Supports connection-oriented style authentication.

    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.

    SECPKG_FLAG_IMPERSONATION

    Supports 32-bit Windows impersonation in server contexts.

    SECPKG_FLAG_ACCEPT_WIN32_NAME

    Understands 32-bit Windows principal and target names.

    SECPKG_FLAG_STREAM

    Supports stream semantics.
  • wVersion
    Version of the package protocol, which must be 1.
  • wRPCID
    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
    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, which can be any additional string passed back by the package.
