.. py:class:: Blob(data: bytes)


   Represents a DPAPI blob.

   .. py:method:: decrypt(master_key: bytes, entropy: Optional[bytes] = None, strong_password: Optional[str] = None, smart_card_secret: Optional[bytes] = None) -> bool

      Try to decrypt the blob with the given master key.

      :param master_key: Decrypted master key value.
      :param entropy: Optional entropy for decrypting the blob.
      :param strong_password: Optional password for decrypting the blob.
      :param smart_card_secret: MS Next Gen Crypto secret (e.g. from PIN code).

      :returns: True if decryption is succesful, False otherwise.


   .. py:method:: __repr__() -> str

      Return repr(self).
