Since it’s quite annoying to get the invalid certificate warning every time I connect to my switch, I want to install a custom HTTPS certificate signed by a Certificate Authority my machines trust. But I can’t figure out Netgear’s ridiculous certificate configuration UI. It only gives the option to upload the following:
- SSL Trusted Root Certificate PEM File
- SSL Server Certificate PEM File
- SSL DH Weak Encryption Parameter PEM File
- SSL DH Strong Encryption Parameter PEM File
There’s no option to upload a key, or to generate a CSR on the switch (like any sane security system would). The Netgear forums indicate there’s some magic combination of how to do this, but most posts are either incomplete or don’t advise how to get a CA-signed cert to work (only a lone, self-signed key). The official manual is even less helpful, saying nothing more than “[ensure] the file is in the correct format”.
What’s the right way to configure this?
