module HexaPDF:: Filter:: Encryption
This filter module allows access to the standard encryption and decryption routines implemented by the SecurityHandler using the standard Filter interface.
The options hash for ::decoder and ::encoder must contain two keys: :key (the encryption/decryption key) and :algorithm (the class used for encrypting/decrypting).
This module must not be confused with the Crypt filter specified in the PDF specification!
