hello, In C# our maintainance project, we observered that the previous company has a root certificate. This certificate is valid in domain only, for 2020. How can they create such a root certificate free. Can anyone guide us.
Thanks in advance

Anyone can create a certificate using Makecert.exe. But it obviously won't be from a trusted authority.
You can manage certificates with certmgr.exe
I believe GoDaddy issues generic certificates (we have one here). They cost a little more, but cover the sub-domains.
If you are asking for how to do it for free. You need to set up a certificate server (or use makecert like Mitch said if you don't care about a trusted certificate), and become a certificate authority (I don't mean like GoDaddy etc., although they are one). To get people to accept the certificate, you need them to trust the authority.
you can generate certificates you need with X509Builder web application at http://www.we-coffee.com/x509builder.aspx
