Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`sign(byte[] data, int offset, int length, CommonServerMessageBlock request, CommonServerMessageBlock response)`	Performs MAC signing of the SMB.
`boolean`	`verify(byte[] data, int offset, int length, int extraPad, CommonServerMessageBlock msg)`	Performs MAC signature verification.

- Method Detail
  - sign
```
void sign(byte[] data,
          int offset,
          int length,
          CommonServerMessageBlock request,
          CommonServerMessageBlock response)
```
    Performs MAC signing of the SMB. This is done as follows. The signature field of the SMB is overwritten with the sequence number; The MD5 digest of the MAC signing key + the entire SMB is taken; The first 8 bytes of this are placed in the signature field.
    
    Parameters:
    
    data - The data.
    
    offset - The starting offset at which the SMB header begins.
    
    length - The length of the SMB data starting at offset.
    
    request - request message
    
    response - response message
  - verify
```
boolean verify(byte[] data,
               int offset,
               int length,
               int extraPad,
               CommonServerMessageBlock msg)
```
    Performs MAC signature verification. This calculates the signature of the SMB and compares it to the signature field on the SMB itself.
    
    Parameters:
    
    data - The data.
    
    offset - The starting offset at which the SMB header begins.
    
    length -
    
    extraPad - extra padding to include in signature
    
    msg - The message to verify
    
    Returns:
    
    whether verification was unsuccessful
