We have just setup a web site , IE and firefox works fine to access it , but when use Chrome , the https is not works , it pops the below error , would advise how can I fix it ? thanks
mysite.com
identity not verified.
the identity of this website has been verified by geo trust ssl CA but does not have public audit records.
the site is using outdate security setting that may prevent future version of Chrome from being able to safely access it.
Your connection to mysite.com is encrypted with obsolete cryptography.
the connection uses TLS 1.2.
the connection is encrypted using RC4_128 with SHA1 for message authentication and RSA as the key exchange mechanism.
If you see an SSL error message in Chrome saying "Your connection is not private," it means your Internet connection, or your computer, is stopping Chrome from loading the page securely.
If you are a web user and you see this warning, you can contact the site owner to make sure that they are aware of the warning. The site is no less secure today than it was last month, but Google is starting to bring awareness to the less secure SHA-1 signed certificates.
The certificate is unable to be audited. In other words, it does not
have the necessary information to be able to go to the CA and check if
the certificate has been manually revoked prior to its expiration.
HTTPS sites whose certificate chains use SHA-1 and are valid past 1 January 2017 will no longer appear to be fully trustworthy in Chrome's user interface.

I have a secured website using a Network Solutions SSL cert. The website can be accessed from computers in environments in my company which have access to the Internet. (IIS redirects http calls to https). I have a browser in a locked down environment trying to access the same website using https. The locked down environment doesn't have access to the Internet but ports 80 and 443 are open to the website's server and I verified responses from telneting to ports 80 & 443. (not related to the error anyways). The IIS server has access to the Internet.
The response in IE is shown below.
Is the IE problem in that it doesn't have Internet access and so it can't connect to Network Solutions (NS) for verification or is it because of maybe missing root cert for NS? NS is a known authority so this is unlikely.
(I am troubleshooting WebAPI calls using https in case someone decides this is not a programming question. I have to make IE work correctly on the same machine before I look at the webapi stuff)
TL;TR: usually no internet access is needed to check the certificate on internal sites, but there are some edge cases.
There is no internet needed to access an internal site which has a certificate signed by an internal CA. There is also no internet access needed in most cases if the internal site has a certificate signed by a common public (i.e. external CA). There might be a slowdown in this case since it might try to check online for revocation information but in most cases it will just continue if it cannot reach the server for revocation checks. It might fail if the certificate is an EV certificate or if the browser is configured to do more strict revocation checks than usual.
But in your case it shows that the certificate was issued by an unknown CA. This means either the root CA for this certificate is not known at all on your system or the server failed to send the intermediate certificates required to build the trust path to the root CA. In the last case some browsers are able to work around such broken configuration by downloading the missing intermediate certificates from the internet - which of course requires internet access then. In the first case (missing root CA) an update of the root CA store could help which Microsoft browsers might do in the background if they have internet access.
I am trying to wrap my head around certificates and any help is appreciated. So far this is what I understand, please correct me if I am wrong.
When using the browser when I navigate to the https site the browser downloads the certificate(without the private key) and then continues to send the data over https?
I have come across some sites (especially when developing) that require you to install the certificate on the local machine before making a service call. What is the purpose here and how does it work?
I have also seen some scenarios where you need to install the certificate on the client machine for authentication purposes for example if you are using an email client, how does this work?

No, the browser and the server stablish a SSL/TLS secure channel with a symmetric encryption key. During the handshake process the server presents the https certificate and digitally signs some data with the private key as a proof of authenticity.

The client must trust the server certificate. Usually it has a list with the Certification Authorities for which certificates are accepted. For other certificates is needed to add them to the trust list. If not, the communication will be rejected

Probably the same case as the previous one. Also the public part of the certificate of a user can be used to encrypt a message for him
We've an ASP.NET MVC4 app where there is a part which should be secured through client certificates.
When anyone wants to connect to this part of the app, browsers should ask them for a client certificate, once they select it, our server will get it, check it's validity and show the content.
Ok, I'm getting trouble with the select certificate part. Before setting it just to one folder on views content, I'm trying to configure this on the global app.
I've set SSL to be required, and also set require client certificates on SSL Configuration on apps configuration on IIS.
I've enabled the iisClientCertificateMappingAuthentication (although I've set no mapping yet)
When I try to access the app both, Firefox and Chrome, return a 403 forbidden error, stating that I have no access to the app with the credentials provided.
I've a client certificate installed on my local machine and the CA who created this certificate as a trusted root certificate on server local machine.
I'm not being prompted for certificate.
If I uncheck the "require" from client certificates on SSL Settings, I can access the app through https.
This is the first time I work with client certificates, so it's being a bit confusing and maybe I'm not giving enough info. Feel fre to ask for further info on the comments.
EDIT: I've exported the client certificate, copied it to the server and checked it there. The certificate shows as valid and every element in the certification chain seems to be recognized in the server.
I've checked IIS logs also, and the error I'm getting is 403.7, so the certificate is not being issued to the server or it's invalid.
Now... I've checked that the certificate is valid on the server, it's correctly installed on the client but it's not getting to the server or is not beign validated there... what am I missing here?
Ok, finally I've found the problem, it's related to the buffer size reserved for the list of trusted certification authorities.
Check this kb article:
https://support.microsoft.com/en-us/kb/933430
TL DR; To solve the problem just add a new entry in the registry at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
named SendTrustedIssuerList as a DWORD value with value 0.
This way, the server won't send the trusted certification authorities list, so browsers will display the complete list of certificates to the user.
Ever since moving an internal apex website from the embedded PL/SQL gateway to a weblogic server browsers throw certificate errors.
How can i get rid of these errors/fix the certificates?
Internet Explorer:
The security certificate presented by this website was not issued by
a trusted certificate authority. Security certificate problems may
indicate an attempt to fool you or intercept any data you send to the server
Chrome:
You attempted to reach sy02131.adt.com, but the server presented a
certificate issued by an entity that is not trusted by your computer's
operating system. This may mean that the server has generated its own
security credentials, which Google Chrome cannot rely on for identity
information, or an attacker may be trying to intercept your communications.
Out of the box, the embedded SQL gateway (EPG) uses no SSL. It looks like your Weblogic instance did or even requires SSL. It's probably using a set of starter keys that you're meant to replace. At any rate, your browser is causing this problem, not the server. You should be able to bypass this as a warning in the browser or add an exception. If you want this error to go away in production, get some proper SSL keys from a certificate authority.
Here is how to configure them once you get them:

I need to implement a SSL certificate for a website, I've got three questions after some research.
1) I believe i need to buy a SSL certificate and ask my host to install it. My question is do you need to alter any code for the website for the certificate?
2) Before I buy the certificate, the website is going to be built for a couple of month at least. I'm just wondering is there a developing SSL certificate I can use for the developing environment?
3) Or do I have to use self assigned certificate? If so are there any good tutorials on how to create a SSL self assigned certificate on a local machine (wamp) and a developing url site?
Thank you very much.
Sam :)
1) No, you do not need to alter any code on your website at all in order to use an installed SSL certificate. It is as simple as prefixing your desired destination link with the HTTPS: protocol specification instead of the typical HTTP: protocol. However, if you want to determine if your site visitor is using an encrypted page before they do something, such as submit a web form with potentially sensitive data, then depending on what you are developing your site in, you will need to detect if the current page request has been sent over HTTP or HTTPS, then if it is an HTTP requested page, you probably want to redirect the page request to the HTTPS version before proceeding.
2) Other than creating your own "self signed" certificate (more on this in #3), no your only option for a publicly valid SSL certificate is to obtain one from a publicly recognized Certificate Authority (CA). Long story short, a certificate of the same key length using the same encryption standard supported by your server and visitor's web browser, is no stronger or weaker regardless of vendor for purposes of encryption. So you can simply shop by price for your SSL certs. I have no affiliation with GoDaddy, but have been using them for years for public SSL certificates.
3) You certainly can create your own self signed certificate. The methods for doing this vary based on your host server and version. The limitation to a self signed certificate, is that if you go to share this with anyone, you get that warning message from your browser that the certificate is not published from a verifiable source. In most current browsers, it looks like a big scary message that something is wrong and they attempt to warn your user away from doing this. However, of course, there is certainly nothing wrong with using a self signed certificate. This is obviously true for your own development uses. Even a self signed certificate of the same key length and encryption method is as cryptographically secure as a commercially provided certificate. If you want to use a self signed certificate, just search for instruction for doing that for your server OS and version for details. Once it is installed, you will get the warning from your browser when you try to browse to a page over HTTPS. Your browser should show you an option to permanently remember and accept your self signed certificate, after which you will no longer see that warning while that certificate remains installed and valid.
