.. py:class:: CryptStream(fh: BinaryIO, cipher: str, key: bytes, key_size: int | None = None, offset: int = 0, size: int | str | None = None, iv_tweak: int = 0, sector_size: int = 512)

   Bases: :py:obj:`dissect.util.stream.AlignedStream`


   Transparently decrypting stream.

   :param fh: The original file-like object, usually the encrypted disk.
   :param cipher: The cipher name/specification.
   :param key: The encryption key.
   :param key_size: Optional key size hint.
   :param offset: Optional base offset to the encrypted region. Segment offset in LUKS.
   :param size: Optional size hint. If ``None`` or ``"dynamic"``, determine the size by seeking to the end of ``fh``.
   :param iv_tweak: Optional IV tweak, or offset.
   :param sector_size: Optional sector size. Defaults to 512.
