I have a website running on AWS that needs SSL. The website has the functionality that it must by white labelable according to the subdomain accessed. For example, when accessing www.a.the-site.com the website will look different from when it is accessed from www.b.the-site.com, but it is the same virtual host handling both urls. I use an ELB which directs to the EC2 instance (only one instance at this stage) This worked fine when running over normal http.
I followed the step by step tutorial on AWS (http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/ssl-server-cert.html and http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-create-https-ssl-load-balancer.html#configure-https-listener) to generate the keys (steps laid out below for ease of reference) and got the certificate from GoDaddy. (Upon pasting the CSR on the GoDaddy website's certificate request process, the correct CN was displayed). The certificate bought was a wildcard certificate, to support different subdomains. I applied the Certificate on the ELB using the AWS website interface, which did not prompt any errors, but now when I access the site over https, I get the SSL error in the browser:
"The security certificate presented by this website was issued for a different website's address."
Investigating the Certificate on https://www.sslshopper.com shows the following:
It states that none of the common names match, yet the common name in the chain is correct (*.the-site.com)
I can also post the steps followed to create the private key and CSR, but I have not received any indication that these are incorrect. It seems like the CN *.the-site.com is not resolving www.a.the-site.com. Can anyone shed some light on this?
#Michael - sqlbot was correct, the wildcard certificate only checks for a single domain. I changed my domain settings to not redirect to www.a.example.com, but rather a.example.com (dropping the www subdomain) and all is working as expected.

Ours is a educational website collegesearch.in which is HTTPS secured. We are loosing our desktop traffic because we get error like untrusted certificate on public domain networks and also some of the antiviruses block our website as well. There is no issue with our certificate and they are issued by CSA and are not self-signed.
We understand some of the pages may include mixed content like stuffed http links, which we identify and remove but this itself does not seem to be the reason of traffic drop.
We have 75% mobile users and only ~20% of desktop, while our competitors have 40% of desktop users and they are http websites. This makes us think that using HTTPS has become ironically a problem.
My question is What makes antiviruses block HTTPS website?
Why we get untrusted certicate error?
Anything that can help here...
The site collegesearch.in:
is using a self-signed certificate and thus is not trusted by default by any browsers
on top of this the certificate is expired
on top of this the name in the certificate does not match the URL
on top of that you are offering insecure ciphers
For more details see the SSLLabs report.
Interestingly, www.collegesearch.in is setup in a different way although it still offers some weak ciphers.
It looks like that you are trying to deal with the badly setup collegesearch.in by redirecting users to www.collegesearch.in. But, for the redirect to work the user is first confronted with the bad certificate from collegesearch.in which he must accept before the browsers continues with the HTTP request which then results in the redirect to www.collegesearch.in. To fix this you need to have a proper certificate setup not only for www.collegesearch.in but also collegesearch.in.

I built a simple website for my mother's business. There is no login, database, or any sort of form or payment happening on the site. I do not have an SSL Certificate and was wondering if a self-signed one offered by cPanel hosting would suffice? I would hate to shell out money for encryption I don't need yet. The main reason I need it is so that the browsers stop blocking my https connection. Any information I can get on this would be a big help.
Rather than selecting a self-signed SSL Certificate, you better go with the Free/Trial SSL Certificate offered by some of world's leading SSL Certificate authorities like Comodo, Symantec and RapidSSL.
Why no to Self-Signed SSL Certificate?
Not accepted by most browsers
Browser will display untrusted connection error message
Why Free/Trial SSL Certificate?
Compatible with multiple servers and operating system platforms.
Accepted by 99.9% web and mobile browsers (No Error after installation)
It will give trust and confidence to users as the SSL is from verified SSL authority
Increases website reputation over internet.

Our company recently implemented Zscaler proxy filtering, which I just learned uses a root certificate pushed out to all of our machines to forge SSL certificates for mitm filtering of our traffic. Personally I'm not happy about this, but we do a lot of sensitive work, so I'm not going to complain.
But now I'm noticing they don't seem to be doing it consistently. For instance, if I go to Facebook on the work network, the certificate is signed by ZScaler Intermediate Root CA, which clearly means it's been compromised. But if I go to, say, my bank, it says it's signed by Verisign. Am I right in thinking that means the bank connection has not been intercepted and is still end to end encrypted?
Zscaler allows the administrator to configure which sites/domains/categories will or will not be decrypted for inspection. It sounds like your admins have disabled SSL decryption sites in the finance category, and thus traffic to your bank is not being decrypted, whilst traffic to Facebook is.
As far as determining which traffic is and is not being decrypted you are exactly right - check the SSL certificate and if it's signed by the Zscaler certificate then the traffic is being Man-In-The-Middle'ed. If it's signed by any other certificate (including Verisign/etc) then it's NOT being MITM'ed.

What I want to do is making my website available via https without getting these browser warning that the site is not trusted.
I created an SSL certificate for my domain and configured Apache webserver to use it in default-ssl. Calling my site with https:// works, but in every browser on every device a get the message that no issuer chain was provided. In firefox like:
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)
What did I understand wrong with SSL?
The certificate you get is not directly signed by the Root-CA, but by an intermediate CA, which by itself got signed by the Root-CA. You have to add this intermediate CA to the certificates your server sends to the client, because the client only trusts the Root-CA and does not now the intermediate CA.
The process is described in various places, like https://eldon.me/?p=34
You say Startcom SSL - do you mean the free one? If so - that's a normal and import behavior of these browsers (well your free certificate isn't validated - no prove that this certificate really belongs to you). I actually hope there is no way around that.
Don't get me wrong - CA's have their advantages as well as disadvantages. What you could do for your users is take part in the web of trust, yet it won't help on that topic.
What you personally can do, is view the certificate (when the warning is displayed - don't directly click for a temporary exception) and then, there is an option to permanently save an exception for that certificate.
But you have to do that on every browser (once) and just works for you, every other user visiting the site has to do the same.

I'd like to authenticate the users to my website by checking their SSL client certificate information. I'm going to be using an Apache server, and I'd like to check that their certificates authenticate the users as members of certain organizations.
How can I do that?
In a nutshell:
Obtain an SSL Certificate for whichever domain you need, this could be the main domain, subdomain, wildcard, etc. If your going to have multiple subdomains then a wildcard is the way to go. SSL Certificates can be purchased from most hosting companies, for example 123-reg provide them.
Install Certificate on Apache, depending on OS platform this could be via updating httpd.conf or ssl.conf to reference the SSL Certificate, key, pem files, etc. You will need to modify the various SSLCertificate... directives, take a look at ssl.conf for the example configuration.
Setup whatever authentication you require for Apache hosted site, for example, setup the users using htpasswd.
End users then need to install the certificate upon first connecting to the https site, this is done client side and may require admin rights to add to client PC.
Most certificate providers give full installation instructions.
