Some of the documentation around creating certificates for vCenter or SRM seems to be lacking, so I documented a few steps for each and outlined the differences, also created a video :)
This can be done from any machine, as long as openssl is installed. If you’re creating/requesting multiple certs, create folders for each request and work from within there so you don’t mix them up. I use d:\cert\vcenter and d:\cert\srm. I added “D:\OpenSSL-Win32\bin\” to may path variable so it’ll work in any folder I’m in.
