I'm working with X509 certificates with my website. And I have created client certificates for testing.
The issue is that even though a single certificate is installed, chrome shows the certificate selection prompt. We have an option under IE to disable the same but I couldn't find any such option under Chrome.
I have searched but haven't found a satisfactory answer.
The closest I could get to solving the issue was with this link. This is for Chromium however I have read somewhere that Chrome uses a similar approach for this policy.
Sadly the Windows registry does not contain such a value :-
Software\Policies\Chrome
Any help with this deeply appreciated.

This started happening just a few days ago. I can access the site on the same computer in Firefox. Not sure why it is telling me that the site is insecure, but that must be related. I tried ipconfig /flushdns, deleting my cookies, and disabling my firewall but none of those fixed it. Can't find any solutions online either so far. Using the latest Chrome update and Windows 10. Please help!
Edit: Solved my issue by installing this Windows update:

It is possible that you might have deleted trusted certificates from chrome trust store (github CA SSL certificate is issued by DigiCert High Assurance EV Root CA ), where as in for other browsers the trust store must be a different location in your case.
To check above listed certificate present in Chrome trusted store or not, do the following
Open Chrome then Go to Settings => Manage Certificates - Click on it, when Certificates pop-up shows then check at' Trusted Root Certificates Authorities, if desired certificate is not present then import it.
For what it's worth, this is what worked for me:
Open up the start menu and search for and open "Internet Options".
Go to the "Connections" tab.
Click on "LAN settings".
Untick all the checkboxes (there are 3).
Click OK twice and then access https://github.com/ via Google Chrome.
The reason why it works on Firefox is because it has its own proxy settings. Google Chrome takes the proxy settings of the computer.
If you enter the website URL with www, it will work in chrome.
To avoid this you need to add another CNAME without www.
I am using MacOS and I had similar issue of accessing GitLab with Chrome, but no issue with Safari.
What helps me finally is: Setting -> Privacy and Security, and turn off "Use Secure DNS".
If CORS extension has been downloaded and enabled in the Chrome browser then disable the CORS(Allow-control-Allow-origin) extension. It will work..!
I'm creating an API using node js and express. As we are moving towards production, I decided to encrypt the api using ssl, (simply adding the require 'https' option and creating the requires key and cert files using openssl).
I want to continue working on the API using postman (chrome plugin), so to enable me to do this, I visited the API using Chrome, saved the cert for the API to disk and then imported that cert file (cer format) to the "personal" certificate store in Chrome. So far, so simple.
I was then able to start using the API over ssl as expected. Great.
Now, where it is starting to get a bit odd is that if I want to then remove that certificate from my personal certificate store in chrome, I was expecting to be able to just open up the settings - > htttps - > manage certificates and then to be able to remove the certificate, however the certificate is not visible in the list of certs. It's clearly been imported and is working, it's just not showing in the list. The machine in question is running win 10, so I also checked the certificate management console for the machine and I searched for the cert and cannot find it anywhere.
I think that this should be really simple, so where is that cert that I imported (and which is clearly imported and working) so that I can remove it?
Thanks!
So, I finally found the solution to this. From the command line start "certmgr" and from there I can see the installed certificate and remove it. Not sure why it doesn't show up when viewed from within Chrome?!
I want to use fiddler to monitor api calls made by my browser when it visits some pages.
The technology - Fiddler 4.6x, Chrome 56, Firefox 51, Windows 7 64 bit.
The problem - Fiddler does not work with chrome. When I open any page on chrome, I get the error "Your connection is not private: Attackers might be trying to steal your information from website (for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID". FYI, I easily fixed a similar issue with firefox.
Solutions I tried that failed -
Four hours of google and stack overflow did not give me any solutions.
Convert the fiddler cert to pk 7 ??? format.
Import fiddler cert into chrome. Also, grant the cert all kinds of advanced permissions.
Install the fiddler cert with admin rights on windows, by "running" it.
Run chrome and ignore cert errors.
Regenerating the fiddler cert and restarting fiddler and browsers as given in the official fiddler book.
In 2,3 the cert never appeared in trusted cert store, but appeared in personal and immediate cert store. In 1, nothing even happened. Please tell me how I can make this work. Any links to the basics of all this would help.
I was facing similar issue with Fiddler v4.6 and followed these steps:
Fiddler 4.6.1.5+
Click Tools > Fiddler Options.
Click the HTTPS tab.
Ensure that the text says Certificates generated by CertEnroll engine.
Click Actions > Reset Certificates. This may take a minute.
Accept all prompts
Fiddler 4.6.1.4 and earlier
Click Tools > Fiddler Options.
Click the HTTPS tab
Uncheck the Decrypt HTTPS traffic checkbox
Click the Remove Interception Certificates button. This may take a minute.
Accept all of the prompts that appear (e.g. Do you want to delete these certificates, etc)
(Optional) Click the Fiddler.DefaultCertificateProvider link and verify that the dropdown is set to CertEnroll
Exit and restart Fiddler
Click Tools > Fiddler Options.
Click the HTTPS tab
Re-check the Decrypt HTTPS traffic checkbox
Accept all of the prompts that appear (e.g. Do you want to trust this root certificate)

I used these two stack overflow posts -
https://superuser.com/questions/145394/windows-7-will-not-install-a-root-certificate
https://superuser.com/questions/647036/view-install-certificates-for-local-machine-store-on-windows-7
I don't know what is happening. One of these posts worked and I got the fiddler cert into the trusted store. But, fiddler still cannot decrypt many websites https traffic, especially that of google.
After I reinstalled fiddler and did what Abir suggested Fiddler still didn't capture any traffic.
In my case it stopped working because I installed a chrome extension named Tunnel Bear, uninstalling the extension solved it for me.
Firefox has its own certificate store so I assume you just installed the DO_NOT_TRUST... Fiddler root cert there and everything worked. Pretty much you should do the same with Windows certificate store in order for Chrome to work. So make sure you remove all the fiddler certificates you previously generated and regenerate.
if fiddler do not capture chrome traffic, one solution is checking extensions. in my case i use zenmate vpn. when i disable this extension, fiddler capture all traffic in chrome
When i tried to open my site (https://thaimeditationcenter.com/) by Google Chrome on My mac using macOS Sierra Version 10.12 i got an error like this.
Your connection is not private
Attackers might be trying to steal your information from thaimeditationcenter.com
(for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID
Automatically report details of possible security incidents to Google. Privacy policy
But when i open it on Firefox , Safari or Google chrome on my Iphone it seems fine there was no error at all.
How can i fix this?
Thanks!
According to SSLLabs your site is not configured properly:
Chain issues Incomplete
This means that a chain certificates is missing. Some browsers cache chain certificates when visiting other sites and therefore can work around this problem. Other browsers try to download the missing chain certificate. The rest will fail because the trust chain cannot be built.
To fix this you need to add the missing chain certificate to your server configuration. While doing that you should probably also fix all the other problems shown by the SSLLabs report which lead to a bad Grade F for your site.
I am able to access a URL in Chrome 36 and IE8 but in Chrome 39 or 40 or Firefox 35 it throws the error:
Unable to make a secure connection to the server. This may be a
problem with the server, or it may be requiring a client
authentication certificate that you don't have.
Error code: ERR_SSL_PROTOCOL_ERROR}.
It seems that it is an issue related to the SSL certificate. How can I fix this?
Google announced that they would begin removing support for SHA-1 cryptographic hash algorithm beginning with Chrome 39. According to Google:
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.
There are several sites which can provide detailed analysis of your SSL certificate chain, such as Qualys SSL Labs' SSL Test.
Google Chrome does have a highly risky command-line option --ignore-certificate-errors which might bypass certain certificate errors. Be aware that ignoring certificate errors puts all of your SSL traffic at risk of being eavesdropped on.
It's also possible that this is a new bug. Google switched from using OpenSSL library to it's own "BoringSSL" library in Chrome 38. To report a bug in Chrome visit chrome://help/ and click "Report an issue".
Try this. In Chrome, enter "chrome://flags/#enable-quic" without the quotes as a URL. CTRL + F to search for "quic", at which point you'll find...
Experimental QUIC protocol. Mac, Windows, Linux, Chrome OS, Android
Enable experimental QUIC protocol support. #enable-quic
Turn that to disabled, and let it restart your browser when prompted below.
Go to Windows Firewall, click on "Restore Defaults", then again. The problem should be fixed.
For me this issue resolved when I turned off my Antivirus Browsing control.
First check that in :
Internet Explorer- go to tools/internet options/advanced in the settings box, scroll all the way to the bottom and select Use TLS 1.0 and it will fix the problem.
SSL 2.0 or 3.0 and these are should also be selected.
Google Chrome-Click "wrench" sign on the tope right of it.Click Options then Under the bonnet in network click Change Proxy Settings and follow the steps above as in Internet Explorer.
If this didn't work try the following steps:
Unhide all the files and folders.
Then go to C:\Windows\System32\drivers\etc\hosts.
Right click on hosts file,then click properties. Then click security tab. After that click edit.
Here,click system and you have to check on allow full control and uncheck deny.
Click OK and then OK.
Now delete the hosts file.

or you get all the details solution about err_ssl_protocol_error from here. I hope this will work and fix the error.
