Repeated calls are equivalent to a single call with the concatenation of all the arguments. In other words: >>> m.update(a); m.update(b) is equivalent to: >>> m.update(a+b) :Parameters: data : byte string/byte array/memoryview The next chunk of the message being hashed. r N)r � md4_updater r r r �lenr )r r r s r r zMD4Hash.updateZ st � �" �(�(��� � �):�):�)4�T�):�):�)1�#�d�)�)�)<�)<�>� >�� � '� � ?� %� &� '� '� '� '� 'r c �� � t | j � � }t � | j � � � |� � }|rt d|z � � �t |� � S )ar Return the **binary** (non-printable) digest of the message that has been hashed so far.
