I've been trying to ensure that there is no issues with subj. compliance, but finally didn't find any evidence that OpenSSL used by VixDiskLib is compliant. Could you please elaborate on this topic? Not that I'm nitpicking, but some customers really do
VixDiskLib is a library from VMware VDDK, so I would suggest asking this question from them directly, as only these guys can you give the details you need.
