Hello users, i want share my experience with this free certification authority, so you all can make free basic ssl certificate for Your website or hosting panel itself there with no cost. And with this lines You can save a lot of time googling http://www.startssl.com/ Problem is installation into ispconfig2 system, where procedure for ssl setting is another. My situation was easy, i create certificate for my website, i get encrypted private key which i decrypt using web tool also in user panel there.. So i have encrypted and decrypted private key, next is result which was certificate for my website valid for required domain name. Cheers nice, but what next. Problem is that you cannot get normally CSR file which is request itself, that is not normal cos usually You make request on your webserver and some CA will sign you this request and you will get Your certificate, this time you don't have CSR, but you can get it using this command in your ispconfig installation you have all what you need. I assuming You have all two files which is needed by this command, you need private key, decrypted, and certificate file crt itself, result will be our csr which we don't see in procedure itself at CA side and is needed by normal UI SSL setting at ispconfig2 Code: openssl x509 -x509toreq -in domain.crt -out domain.csr -signkey domain.key copy that thre files into your ssl directory inside client website in format domain.tld.key domain.tld.crt domain.tld.csr Then in ispconfig system in domain tab ssl just click create certificate in Action section. Then you can check your webpage https version and will be ready for You. This setup worked for me.
