Create a new HMAC object. key: bytes or buffer, key for the keyed hash object. msg: bytes or buffer, Initial input for the hash or None. digestmod: A hash name suitable for hashlib.new(). *OR* A hashlib constructor returning a new hash object. *OR* A module supporting PEP 247. Required as of 3.8, despite its position after the optional msg argument. Passing it as a keyword argument is recommended, though not required for legacy API reasons. z,key: expected bytes or bytearray, but got %rz'Missing required parameter 'digestmod'.r c s t �� | �S �N��_hashlib�new��d�� digestmodr r �<lambda>= r zHMAC.__init__.<locals>.<lambda>c s � � | �S r �r r r r r r ? r r � z:block_size of %d seems too small; using our default of %d.� z<No block_size attribute on given digest object; Assuming %d.� N)r )r )� isinstance�bytes� bytearray� TypeError�type�__name__�callabler �strr r r �hasattrr � _warnings�warn� blocksize�RuntimeWarning�len�digest�ljust�update� translate�trans_5C�trans_36)�self�key�msgr r- r r r �__init__&
