SecPkgContext_Sizes
The SecPkgContext_Sizes 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, * PSecPkgContext_Sizes;
Members
-
cbMaxToken
-
Specifies the maximum size of the security token used in the authentication exchanges.
-
cbMaxSignature
-
Specifies the maximum size of the signature created by the MakeSignature function. This member should be zero if integrity services are not requested or available.
-
cbBlockSize
-
Specifies the 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.
