I don't think so. I did a quick little proof of concept implementation
(which would work for any algorithm supported by the digest stuff) and
it ended up like:
size lib/md5.o common/digest.o commands/md5.o
text data bss dec hex filename
2841 152 0 2993 bb1 lib/md5.o
339 16 0 355 163 common/digest.o
969 0 0 969 3c9 commands/md5.o
So less than 1K if you already use md5/digest for something else,
I'll clean up the code a bit more and send a patch.
