Hello All,

 

I would like to know how we can generate the Self Signed Wildcard certificate using the keytool utility? If not possible through keytool, is there any other way using which we can generate the Self signed Wildcard certificate?

 

Thanks,

Avinash

Hi @HelesicPetr 

 

Thanks for your reply.

From the shared Article and as per below snapshot, do we need to enter domain details in First and Last name?

e.g., CN=*.abc.com

If you generate certificate for some address you need to define full address. 

So yes you also need to use domain address

Looks like you have to modify the .cnf file to be able to do it
