      Description copied from interface: `PGPDataDecryptorFactory`
      Constructs a data decryptor.
      Specified by:
        `createDataDecryptor` in interface `PGPDataDecryptorFactory`
      Parameters:
        `withIntegrityPacket` - `true` if the packet to be decrypted has integrity checking enabled.
        `encAlgorithm` - the identifier of the `encryption algorithm` to decrypt with.
        `key` - the bytes of the key for the cipher.
      Returns:
        a data decryptor that can decrypt (and verify) streams of encrypted data.
      Throws:
        `PGPException` - if an error occurs initialising the decryption and integrity checking functions.
