I just pushed a fix to the repository that increases the maximum
buffer size to 128. Actually I am not sure if we really need such a
hard limit, so I just raised it for now. With BUFSIZE being 16384 that
would result in a maxium size of 2097152 bytes or 2 megabyte. That
should be enough to hold all encrypted data that is required to
decrypt the requested amount of data.

Best regards,
Marc
