Understood.

So about this chunksize, is it ever expected to assume other values
than 1 (for stream ciphers) or the block size (for block ciphers)?
Having block size, IV size *and* chunk size fields may be confusing to
some already, so if the purpose of chunk size can be fulfilled by a
single 'stream cipher' flag, perhaps we should change that first.
