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
Specifies the size of the security trailer to be appended to messages. This member should be zero if the relevant services are not requested or available.
