## 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.

## Constructor Details

### SecPkgContext_Sizes

public SecPkgContext_Sizes()

## Method Details

### 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.
