This structure indicates the sizes of important structures used in the message support functions. The QueryContextAttributes function uses this structure.

typedef struct _SecPkgContext_Sizes {ULONG cbMaxToken;ULONG cbMaxSignature;ULONG cbBlockSize;ULONG cbSecurityTrailer;} SecPkgContext_Sizes, SEC_FAR *PSecPkgContext_Sizes;

Members

  • cbMaxToken
    Maximum size of the security token used in the authentication exchanges*.*
  • cbMaxSignature
    Maximum size of the signature created by the MakeSignature function. This member should be zero if integrity services are not requested or available.
  • cbBlockSize
    Preferred integral size of the messages. For example, 8 indicates that messages should be of size 0 mod 8 for optimal performance. Messages other than this block size can be padded.
  • cbSecurityTrailer
    Size of the security trailer to be appended to messages. This member should be zero if the relevant services are not requested or available.
