Can I use my Stronghold Certificate with SWS?

Yes you can. You should be able to use your certificate from Stronghold with Secure Server without any modifications. Rename your key(s) and certificate(s) to the names specified in the manual, fire up the server, and you should be all set. Just remember that certificates are issued for an IP/domain name pair and cannot be moved to a different IP address or domain.

The correct paths and file names are:

/etc/httpd/conf/ssl.key/server.key

-and-

/etc/httpd/conf/ssl.csr/server.csr

Note that after you receive your key from your chosen authority it will be here:

/etc/httpd/conf/ssl.crt/server.crt
