public void debug(String format, Object... args)

Prints out a formatted string, called in various places inside then NTLM implementation for debugging/logging purposes. When the system property "ntlm.debug" is set, System.out.printf(format, args) is called. This method is designed to be overridden by child classes to match their own debugging/logging mechanisms.

Parameters
format:String

a format string

args:Object[]

the arguments referenced by format

public void debug(byte[] bytes)

Prints out the content of a byte array, called in various places inside the NTLM implementation for debugging/logging purposes. When the system property "ntlm.debug" is set, the hexdump of the array is printed into System.out. This method is designed to be overridden by child classes to match their own debugging/logging mechanisms.
