I suspect no one is even looking at it. Just us :)

Well, today we have OpenSSL 3.2.0 published :

     https://www.openssl.org/source/

So I will try again and this time I will begin with a very stripped down
install of Debian stable. When I mean stripped down I mean there will be
nothing in the base install except reasonable TCP/IP network support and
the ability to FTP a file into it. I can extract a tarball of a decent
compiler that I bootstrapped myself with excellent results :

     https://gcc.gnu.org/pipermail/gcc-testresults/2023-August/794816.html

This will be done on real hardware. Not a virtual machine of any type
where that should make no difference at all. Anyone running ESXi would
see that same results I am seeing anyways.

I want to see if the old sign-file.c code is simply using deprecated
calls and then rewrite/patch as needed. This means the OpenSSL involved
will be the production 3.2.0 release published today.
