I briefly looked into implementing this as a dynamic, however we appear
to lack the needed dynamic functions currently (as of 1.7.9-jumbo-6).
Specifically, I couldn't find a way to reuse raw (as opposed to
hex-encoded) output of SHA-1 for another SHA-1 computation.
Please help implement this dynamic for 1.7.9-jumbo-6 or confirm that
this is not currently possible (and make it possible in a later version).
Thanks,
Alexander
