.. autoapi-nested-parse::

   AES encryption routines

   The `AES` module contains classes used to implement encryption
   and decryption. It aims to be low overhead in terms of memory.





.. py:class:: AES(key, mode=0, iv=None, segment_size=8)

   Encrypt and decrypt AES streams

   .. method:: encrypt_into(src, dest)


      Encrypt the buffer from ``src`` into ``dest``.

      For ECB mode, the buffers must be 16 bytes long.  For CBC mode, the
      buffers must be a multiple of 16 bytes, and must be equal length.  For
      CTX mode, there are no restrictions.


   .. method:: decrypt_into(src, dest)


      Decrypt the buffer from ``src`` into ``dest``.
      For ECB mode, the buffers must be 16 bytes long.  For CBC mode, the
      buffers must be a multiple of 16 bytes, and must be equal length.  For
      CTX mode, there are no restrictions.
