Yes, sure.

There's no reason for upset to create more than one style of checksum.
MD5, SHA512, SHA512/base64, whatever.  What I'm talking about is the
client side.  The setup tool should understand all types of checksums
used.  Right now it identifies MD5 vs. SHA512 just by the length of
the checksum.

CMD is out of the question, this running on a Linux box.

I forgot that the upset repo has been hidden from the public for a long
time, and these days there isn't even a repo since it has been deleted :-P

If you're willing to take a look into these upset perl scripts, please
apply for a normal ssh account on sourceware.org via

  https://sourceware.org/cgi-bin/pdw/ps_form.cgi

Use my private email address as approver.  And make sure to use
*another* public SSH key for shell access than the one you're using
for Cygwin uploads to avoid confusion.


Thanks,
Corinna
