How do I use my sparke server with comodo ssl?
Please refer to this documentation topic:
I Added a comodo ssl on my sparkle server.
comodo will ask for a csr file , i used this tutorial to generate my csr file
that will be a good idea if tmssoftware team add a option to the httpsysconfig tool to build a csr file.
CSR is part of the process for getting a certificate, not for installing the certificate.
HttpSysConfig just binds an existing certificate in the system to be used by the HTTP server.
We have provided tutorials to get free certificate using Let's Encrypt: https://www.tmssoftware.com/site/blog.asp?post=454
And we're working on a new tool that will improve even more the install and maintenance of such free SSL certificates.
