Is it possible to use use the same self-signed certificate for the installation process?
According to the prerequisites, we need one wildcard certificate and one self-signed certificate. We're not planning to buy certificates at this stage yet, so we were wondering if it is possible to use the same self-signed certificate for the installation process?
Yes, you can use the self-signed certificates. For later usage, for example when users want to access KanBo from the Internet, you will need to buy a SSL Certificate from a legal CA. For internal use self-signed are sufficient.
