Hi,
I have a Class 1 StartSSL certificate from StartCom, and I'd like to use for the authentifaction on the router
(for remote admin and SSL VPN).
I loaded the StartCom Class 1 intermediate SA certificate (sub.class1.server.ca.crt) as a Certificate Authority with no problem. The certificate shows up in the Certificate Authorities section, and it says it is valid.
What I am now trying to do is load my class1 client certificate.
The certificates comes as a pfx certificate that contains both the certificate and the private key.
I used openssl to split it into two DER formatted files, one for the certificate, and one for the private key.
However, when I try to load them under Local Certificate & Private Key, I always get an error message saying Invalid certificate file format.
I also tried to load them as pem files, but I got the same message.
What am I doing wrong?
