@FieldOrder({"cbMaxToken","cbMaxSignature","cbBlockSize","cbSecurityTrailer"}) public static class Sspi.SecPkgContext_Sizes extends Structure
The SecPkgContext_Sizes structure indicates the sizes of important structures used in the message support functions.

The `Secur32.QueryContextAttributes(com.sun.jna.platform.win32.Sspi.CtxtHandle, int, com.sun.jna.Structure)` function uses this structure.

- ## Field Details

  - ### cbMaxToken

    public int cbMaxToken
    Specifies the maximum size of the security token used in the authentication exchanges.

  - ### cbMaxSignature

    public int cbMaxSignature
    Specifies the maximum size of the signature created by the MakeSignature function. This member must be zero if integrity services are not requested or available.

  - ### cbBlockSize

    public int cbBlockSize
    Specifies the preferred integral size of the messages. For example, eight indicates that messages should be of size zero mod eight for optimal performance. Messages other than this block size can be padded.

  - ### cbSecurityTrailer

    public int 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.

  - ### toString

    public String toString()
    Description copied from class: `Structure`
    If `jna.dump_memory` is true, will include a native memory dump of the Structure's backing memory.
    Overrides:
      `toString` in class `Structure`
    Returns:
      String representation of this object.
