Because md5 makes more sense for the simple reasons that
1) we already use it in regression tests
2) a md5/md5sum binary is available anywhere, I do not know
something comparable for sha
3) for security-relevant stuff they are all "useless"
Which leaves me to ask: why sha1? I don't really see anything in
its favour (though supporting both, is trivial, the only question
would be how, I do not like any of the methods proposed so far).
