* Byte1('p')
* Identifies the message as a password response. Note that this is also used for GSSAPI and SSPI response messages (which is really a design error, since the contained data is not a null-terminated string in that case, but can be arbitrary binary data).
* Int32
* Length of message contents in bytes, including self.
* String
* The password (encrypted, if requested).
