own self signed SSL certificate. When trying to use this particular feature was when I started to have problems. I navigated to my routers WAN address while on the Internet using Internet Explorer. I fully expected IE to throw an error regarding the certificate. The certificate in the router firmware was bound to be a generic certificate not containing either digital certificate invalid my WAN IP or my FQDN in its subject fields. IE lets you continue if there is a mismatch between what you have typed in your browser’s address field and what is specified in the certificate’s subject field. But instead IE gave me this: As you can see the only option is to close the webpage. IE would not even let me see the certificate and look at the actual certificate error. At this point I switched to Google Chrome to see what it had to offer. This is what it said: Chrome let me continue despite the certificate error and I could access the router’s web pages and also look at the certificate: I exported the certificate and dumped it’s information with certutil.exe: X509 Certificate: Version: 1 Serial Number: f1509cfb65bfbb46 Signature Algorithm: Algorithm ObjectId: 1.2.840.113549.1.1.5 sha1RSA Algorithm Parameters: 05 00 Issuer: E=info@dd-wrt.com CN=NewMedia-NET GmbH OU=DD-WRT O=NewMedia-NET GmbH L=Dresden S=Saxon C=DE Name Hash(sha1): f03bcb463cb28f2c7a590ff0ea429861f2e974b1 Name Hash(md5): 3a7bd1dbec01065f788593f78810a3b5 NotBefore: 28.04.2013 05:46 NotAfter: 26.04.2023 05:46 Subject: E=info@dd-wrt.com CN=NewMedia-NET GmbH OU=DD-WRT O=NewMedia-NET GmbH L=Dresden S=Saxon C=DE Name Hash(sha1): f03bcb463cb28f2c7a590ff0ea429861f2e974b1 Name Hash(md5): 3a7bd1dbec0106

certificate installed (for SSL/TLS data encryption) that cannot be verified by the browser. Internet Explorer: "The security certificate presented by this website was not issued by a trusted certificate authority." Firefox 3: "www.example.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown." or "www.example.com uses an invalid security certificate. The certificate is not trusted because it is self signed." Browsers are made with a built-in list of trusted certificate providers (like DigiCert). For some sites, the certificate provider is not on that list. If this is the case, the browser will warn you that the Certificate Authority (CA) who issued the certificate is not trusted. This issue can also occur if the site has a self-signed certificate. While this warning is fairly generic for Internet Explorer, Firefox 3 will distinguish between a certificate issued by the server itself (a self-signed certificate) and another type of untrusted certificate. If you have a DigiCert certificate and you receive this error, troubleshoot the problem using the sections below. You do not need to install anything on client devices/applications for a DigiCert SSL Certificate to work properly. The first step is to use our SSL Certificate tester to find the cause of error.

Self-signed certificates aren't trusted by browsers because they are generated by your server, not by a CA. You can tell if a certificate is self-signed if a CA is not listed in the issuer field in our SSL Certificate tester. If you find a self-signed certificate on your server after installing a DigiCert certificate, we recommend that you check the installation instructions and make sure that you have completed all of the steps. If you completed all of the installation steps but are still having an issue, you should generate a new CSR from your server (see the CSR creation instructions) and then reissue the certificate in your DigiCert account by logging in, clicking the order number, and then clicking the reissue link. Intermediate Certificate Issues The most common cause of a "certificate not trusted" error is that the certificate installation was not properly completed on the server (or servers) hosting the site. Use our SSL Certificate tester to check for this issue. In the tester, an incomplete installation shows one certificate file and a broken red chain. To
