How to Check Digital Certificates on Computer and iPhone

There are two simple ways to ensure that things are safe quickly, and the website uses encryption with a certificate. First is the presence of a closed padlock icon in the URL bar, and the second is the beginning of the URL as HTTPS instead of HTTP.

Keep data safe. It is vital to ensure that the site you visit transmits your data securely or not. When you view a website’s Certificate, you come to know about the ownership and whether it is secure to transfer your data through this site or not. So if you are looking to view a website’s Certificate, here are easy steps to do so on Safari, Chrome, Firefox, Opera, and even iPhone.

What Details are in a Digital Certificate?

• Who issued the certificate? It may be VeriSign, DigiCert, GlobalSign, or Thawte. These are the companies that, after due process, determined the validity, trustworthiness, and related credibility of the website.
• To whom the certificate is issued? It is the website owner or organization to whom the certificate belongs. Ensure it matches the name of the website or the parent company or the name you expect when you visit that site.

The expiration date of the Certificate: This is mostly one to two years, but sometimes it can be longer than this.

It seems more and more of the general population is starting to take notice of SSL. They expect websites to use it (and are quick to  point out  when they’re not). I’m excited that people are recognizing when a site uses SSL and I’m eager to take that knowledge even further. Beyond just triggering the padlock and HTTPS in browsers, there’s quite a bit more going on within the details of an SSL Certificate. 

What Can You Learn from Digging into the Certificate Details?

There’s a lot of information in a certificate, including basic things like:

• Validity Period.
• Issuing Certificate Authority (CA).
• Subject (the domain it was issued to and depending on the type of certificate, identifying information about the company operating the site).

Certificate contents also cover technical aspects, such as:

• CRL Information.
• Signing and Hashing Algorithms Underlying the Encryption.

This information can be found from right within your browser! Clearly, the importance of these things is going to vary person to person and I don’t expect everyone to start diving into the certificate of every site they visit, but I do want to raise awareness that this type of information exists and how to find it. So let’s get to it.

How to View SSL Certificate Details

Since browsers are updated fairly regularly and SSL presentation in particular is currently undergoing quite a lot of change, I will be updating the sections below as new versions are released. I've noted the versions I used for testing, but for the most part, the same steps  should  apply for older versions as well.

Quick links:

• Chrome - Desktop

Chrome - Mobile

• Internet Explorer

Chrome - Desktop (v.63)

I'm very excited that Chrome has brought back the ability to access certificate details right from the main browser interface. This functionality disappeared for a little while (~v55 - v60) and you had to go through a few mouse clicks to find this info, but now it's very easy. Hooray!

1. Click the padlock in the URL bar. This will trigger a dropdown; click the "Valid" link in the Certificate section. 

EV Certificate in Chrome 68

2. This will bring up the Certificate window where you can click through to your heart’s content. Certificate contents (e.g. subject, validity period, algorithms) are on the “Details” tab.

Certificate details in Chrome

Android (v.67)

Similar to the desktop version, the Android Chrome app makes it pretty easy to dive into certificate details.

1. Click the padlock icon next to the URL. Then click the "Details" link. 

SSL Certificate in Android Chrome App v.67

2. From here you can see some more information about the certificate and encrypted connection, including the issuing CA and some of the cipher, protocol, and algorithm information. To view details more details about the certificate itself, including the validity period and subject details, click "Certificate Information". 

SSL Connection Details in Android Chrome App v.67

3. You can view details for the other certificates in the path by clicking on the dropdown menu highlighted below. 

Full Certificate Details in Android  Chrome  App v.67

Unfortunately, as of this writing at least, it doesn't look like you are able to view much of anything about certificates in the iOS version of Chrome. If you click the padlock icon, you can see the name of the CA that issued the certificate, but that's it. We hope this functionality is added to future versions of the app. 

SSL Certificate in iOS Chrome App v.68

Firefox (v.61)

The latest version of Firefox provides a little more information about the certificate directly in the main browser interface, with the ability to dive into further details with just a few clicks.

1. Clicking the padlock in the address bar brings up a preliminary dropdown that indicates a secure connection when properly configured SSL is in place. Click the arrow to the right of the dropdown to view more information about the certificate.

EV Certificate in Firefox 61

2. In the case of Extended Validation (EV) Certificates, you can see some identifying information about the organization operating the site. For non-EV Certificates (Domain Validated and Organization Validated), you will only see which Certificate Authority (CA) issued the certificate - the “Verified by:” section at the bottom of the pop-up. Click the "More Information" link to view more details. 

EV Certificate in Firefox

Non-EV (OV) Certificate in Firefox

3. This brings you to the security details of the page, where you’ll find more information about the website identity (for EV Certificates, the company name will be listed as the owner) and the protocols, ciphers and keys underlying the encryption.

4. If you want even more details about the certificate (and who doesn’t?), just click “View Certificate.” On the “Details” tab, you’ll find the certificate hierarchy and can dig through the certificate fields. Have fun! 

  Certificate details in Firefox

Internet Explorer (v.11)

Like Firefox, IE provides some certificate information from the main interface.

1. Clicking the padlock brings up the issuing CA (“GlobalSign has identified this site as:”) and a note that the connection to the server is encrypted. There is also some identifying information but again this varies between EV vs. non-EV (DV or OV) Certificates. EV Certificates contain the company name and location, while DV and OV only show the domain.

EV Certificate in IE 11

Non-EV (OV) Certificate in IE 11

2. Clicking the “View Certificates” link at the bottom of the pop up takes you right to the certificate details window. Similar to Chrome, certificate contents (e.g. subject, validity period, algorithms) are on the “Details” tab.

Certificate details window in IE

Edge (v.16)

Bad news for Edge users - there is currently no way to view certificate details using the browser. While some information from the certificate is displayed if you click the padlock, including the Root CA the certificate chains up to and some of the subject information, there is unfortunately no way to view the full certificate path or other details such as validity period, signing algorithms, and Subject Alternative Names (SANs). We hope Microsoft adds this functionality into future versions, but until then, here's how to view the information they do include.

1. Click the padlock to view some information from the certificate. 

  EV Certificate in Edge

DV Certificate in Edge

As you can see in the screenshots above, the type and amount of subject info shown depends on the type of certificate the site is using - EV and OV Certificates display the verified company information included in the certificate's subject fields, but since DV Certificates only vouch for domain ownership, only the domain name is displayed.  

Safari (v.11) - MacOSX

Note: As of this writing, there is no way to view certificate details in mobile (iOS) Safari. 

1. Click on the padlock (you must click the padlock icon specifically; clicking elsewhere will just make the URL appear) to view more details about your connection to the website. If the site is using an EV Certificate, the name of the issuing CA, the company's name, and the company's address will also be shown. Click the "Show Certificate" button to view more information.

  EV Certificate in Safari  

Non-EV (OV) Certificate in Safari

2. You can now see the certificate path, expiration date, and validity. To view additional details, including subject, signing algorithms, and other certificate goodies, click "Details".

Certificate Details in Safari

So there you have it; now you can dive into certificates no matter what browser you’re using. Happy inspecting and safe and secure browsing!

p.s. As I said above, I will try and keep this post updated with the latest browser versions, but if you see I’ve fallen behind, please feel free to give me a friendly nudge in the comments.

[SOLVED] How Do I Fix Safari Certificate Error on Mac?

Safari, the default web browser on Mac, is known for its seamless browsing experience and robust security features. However, there are times when you might encounter a pesky “Certificate Error”  while trying to access certain websites. These errors can be frustrating, but they’re usually a result of security measures designed to protect you from potentially harmful websites. In this guide, we’ll walk you through the common causes of Safari certificate errors  on Mac and provide step-by-step solutions to help you resolve them.

Quick Navigation:

Part 1: Understanding Safari Certificate Errors

Part 2:common causes of safari certificate errors, part 3: how do i fix invalid certificate error on mac.

An “Invalid Certificate Error”  on Mac, specifically when encountered in a web browser like Safari, indicates that there is an issue with the SSL/TLS certificate presented by a website. SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols that provide secure communication over networks, such as the Internet. These protocols ensure that the data exchanged between a user’s device and a website’s server is encrypted and secure.

SSL/TLS certificates play a crucial role in this process by validating the authenticity of a website and establishing a secure connection. When you visit a website, your browser checks the website’s certificate to verify its identity. If the certificate is valid, properly issued by a trusted Certificate Authority (CA), and not expired, your browser establishes a secure connection. However, if there’s an issue with the certificate, you’ll see an “Invalid Certificate Error.”

Certificate errors in Safari  occur when the browser detects an issue with the SSL/TLS certificates used by a website to establish a secure connection. SSL/TLS certificates are digital documents that validate the identity of a website and encrypt data exchanged between the user and the website. When Safari encounters a problem with these certificates, it displays an error message to prevent users from accessing potentially unsafe websites.

There are a few common scenarios that can trigger an “Invalid Certificate Error” , Explore our step-by-step guide on resolving safari certificate errors  and enjoy uninterrupted browsing.

Expired Certificate: SSL/TLS certificates have an expiration date. If the certificate presented by the website has expired, your browser will flag it as invalid.

Untrusted Certificate Authority: If the certificate is not issued by a recognized and trusted Certificate Authority, your browser will treat it as invalid.

Certificate Chain Issues: SSL/TLS certificates are often issued in a chain, with an intermediary CA and a root CA. If any part of this chain is not properly configured or trusted, it can lead to an invalid certificate error.

Hostname Mismatch: The certificate is issued for a specific domain or hostname. If you’re trying to access the site using a different URL, your browser might consider the certificate invalid.

Self-Signed Certificates: Some websites use self-signed certificates instead of those issued by trusted CAs . While they can provide encryption, they’re not automatically trusted by browsers, resulting in an invalid certificate error.

Certificate Revocation: If the website’s certificate has been revoked due to security concerns, your browser will consider it invalid.

Mismatched Public and Private Key: If there’s a mismatch between the public key in the certificate and the corresponding private key on the server, it can lead to an invalid certificate error.

It’s important to note that while encountering an invalid certificate error can be frustrating, these errors are designed to protect users from potentially harmful websites and secure their data. In some cases, you might be able to proceed to the website if you’re certain it’s legitimate, but exercise caution when doing so.

If you encounter an invalid certificate error, it’s recommended to ensure that you’re accessing legitimate and secure websites. If you’re uncertain about the legitimacy of a website or the nature of the error, it’s best to avoid proceeding and potentially exposing your personal information to security risks.

It’s important to take these warnings seriously, as they are designed to protect you from potentially harmful websites and unauthorized access to your data. If you’re certain that the website you’re trying to access is legitimate, you can proceed with caution. However, exercise vigilance and ensure you’re visiting secure websites to avoid falling victim to online scams or security breaches.

Fixing an “Invalid Certificate Error”  on your Mac involves troubleshooting the underlying issues related to SSL/TLS certificates. Here’s a step-by-step guide to help you resolve this error:

Check Date and Time Settings: Click on the Apple menu in the top-left corner of your screen and select “System Preferences.”  Choose “Date & Time”  and ensure that the option to “Set date and time automatically”  is enabled. An incorrect system date and time can trigger certificate errors.

Clear Safari Cache and Cookies : Open Safari and click on “Safari”  in the top menu. Select “Preferences”  and navigate to the “Privacy”  tab. Click “Manage Website Data”  and remove stored data for the affected website. Cached data can sometimes cause certificate errors.

Update Safari: Outdated browsers can sometimes have issues with certificate validation. Check for updates by clicking the Apple menu, selecting “System Preferences,”  and then choosing “Software Update.”  Install any available updates for Safari.

Check the Website URL: Ensure you’re accessing the website using the correct URL and domain. Mismatched URLs can trigger certificate warnings.

Use a Different Browser: If the error persists in Safari, try accessing the website using a different browser like Google Chrome or Mozilla Firefox. This can help determine if the issue is specific to Safari.

Proceed with Caution: If you’re certain that the website is legitimate and you want to proceed despite the certificate error, you can often do so by clicking on the “Advanced”  or “Show Details”  option (if available) on the error page. However, exercise caution when bypassing warnings.

Check the Certificate Chain: Click on the “Advanced”  or “Show Details”  option on the error page to view the certificate details. Verify that the certificate chain is complete and issued by a trusted Certificate Authority. If there are any issues with the chain, it could trigger the error.

Contact Website Support: If you continue to experience the error, reach out to the support team of the website you’re trying to access. They might be able to provide insight or resolve the issue from their end.

Check for Network Interference: If you’re on a network with strict security settings, proxies, or firewalls, they might interfere with SSL/TLS connections. Try accessing the website from a different network to see if the error persists.

Update macOS: Ensure your macOS is up to date. Sometimes, system updates can include security patches that affect SSL/TLS certificate validation.

Scan for Malware or Adware: Use reputable antivirus or antimalware software to scan your Mac for potential malware or adware that might be causing certificate errors.

Remember that while some certificate errors can be bypassed, it’s crucial to exercise caution and only proceed if you’re confident about the legitimacy of the website. Invalid certificate errors are designed to protect your data and privacy, so avoid accessing websites that trigger these warnings unless you’re certain they’re safe.

Encountering a certificate error in Safari  on your Mac might be an inconvenience, but it’s a sign that your browser is working to keep you safe. By following the steps outlined in this guide, you can often resolve these issues and continue browsing securely. Remember, while there are workarounds like bypassing warnings, it’s always best to ensure that you’re visiting legitimate and secure websites to protect your personal information and sensitive data.

HTTPS certificates invalid on Safari, Chrome on specific user account

Safari and Chrome report invalid certificates on certain HTTPS sites (for example GitHub and Bitbucket). Firefox strangely shows a green valid certificate.

I've created a new OS X user and everything is perfectly valid there. I though that maybe there was some invalid certificate in my login keychain. However, even after removing all certs from that keychain, it still reports as invalid.

The Entrust cert that only shows on my account is present in my login keychain. I removed it, which makes the DigiCert High Assurance EV Root CA the new top certificate in the list, but it is not the same cert as on the working account...

The problem also occurs when using curl or for example pushing with git.

Is there something I'm overlooking?

UPDATE Everything works after copying the DigiCert High Assurance EV Root CA from the System Roots to the login keychain. But why is this necessary on my user account?

• certificate

• Is the computer fully up to date with all software patches and updates on the latest version of OSX? –  Darth Android Jul 25, 2014 at 16:01
• Yep, installed all the updates. It feels like somehow Safari is using an old certificate or something. –  Rengers Jul 25, 2014 at 16:03
• 1 When using the search box in Keychain Access to find "digicert high", do you get a single hit? (On my Mac, I only get the one that expires November 2013, and that's in the System Roots.) –  Arjan Jul 25, 2014 at 16:22
• Yes, I only get one certificate that expires 10 november 2031. This cert is in my System Roots. The weird this is: after I copy this to my login keychain (so that I have it twice), it actually works! But why doesn't it pick it up in the System Roots keychain...? –  Rengers Jul 25, 2014 at 16:24
• 1 I just noticed that my Keychain Access did not show any expired root certificates. Enabling that in menu View, Show Expired Certificates might show you another version when searching for "digicert high"? (No changes for me, for that search.) –  Arjan Jul 25, 2014 at 16:42

It seems that somehow Chrome and Safari for that account are using an expired root certificate, even though a new one is already present in your System Roots.

However, by default Keychain Access does not show expired certificates: enable that using menu View, Show Expired Certificates, and then search for the name of the expired certificate, like "digicert high" . Then delete any expired one. As all is fine in a new user account, the culprit must be in your Login Keychain.

(This doesn't explain why Firefox uses the correct one; I would expect all browsers to simply delegate the full validation to OS X, but apparently not.)

• Something to keep in mind: some say that using synchronization through iCloud might actually restore the expired certificate again. –  Arjan Jul 28, 2014 at 20:44
• One final step: restart your browser after deleting any expired certs. @Arjan thanks for the tip! –  schmielson Jul 30, 2014 at 22:23

I had the same problem with my macbook pro and sourcetree app. I followed the instruction provided in the digicert blog (link provided below) to solve this issue.

I'm not 100% sure about the solution.

But same thing happened to me when I set a back date on my PC. Suppose this is 2014. If you set 2013 or 2012 as your year, this problem may happen.

And in this situation, it's really tough to sign in Gmail, Facebook or Yahoo!

Check your date settings.

If you see a 'Not Secure'' warning while browsing with Safari

Safari warns you when a website that you're visiting isn't secure.

In any of these cases, you may see a “Not Secure” or “Website Not Secure” message in Safari:

The website is encrypted, but its certificate is expired or illegitimate.

The website's certificate is valid but the version of TLS is not secure (TLS version 1.1 or earlier).

The website is unencrypted and asking you to enter password or credit card information.

Never enter your password or credit card number on sites with this warning. If you need to use the site, contact its owner or administrator and let them know that their site isn't secure.

How to generate a new Safari Website Push Certificate

Action Needed: Website Push Certificate Expires in 30 Days. Your Website Push Certificate will no longer be valid in 30 days. To generate a new certificate, sign in and visit Certificates, Identifiers & Profiles .

If you run a website that send browser push notifications, you have most likely received this email from Apple reminding you that your push certificate for Safari is about to expire. I’ve been receiving the same email for several years now, but every time I scratch my head wondering how do I do that again.

So this year, I decided to write down the steps and publish them for everyone (but mostly me) to follow again in the future when it’s time to renew the Safari push certificate.

How to renew a Safari Website Push Certificate

In order to generate a new Safari Website Push Certificate, you will need a paid developer account. First you will have to request a certificate from a certificate authority using Keychain Access on your Mac, then you will need to create a Web Push Certificate. We’ll walk you through each step with simple instructions and illustrations.

Note that the following instructions are to generate a Safari push certificate for a website that is already registered to send push notifications. If your website is not registered yet, make sure to login to your Developer account, click on Identifiers  and then click on Register an App ID. Then select Website Push IDs  and click Continue. Type in a description, an identifier, and then click Continue to finalize the registration. Once done, you may go on with the instructions below.

1) First we need to make a certificate signing request. Open Keychain Access on your Mac, then navigate to Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority…

2) Enter your email address and your name, which should already be pre-filled. Leave the CA Email Address field blank, and select to save the request to the disk .

Click Continue, and make sure you save the file to your Desktop for easy reference. You should now have a file titled CertificateSigningRequest.certSigningRequest on your Desktop.

3) Sign into your developer account at developer.apple.com, then click on Certificates, Identifiers & Profiles in the sidebar, and then click on Identifiers in the sidebar.

4)  Click on the dropdown menu at the top right corner of the screen and select Website Push IDs .

5)  Click on the website push ID to select it. Unless you run multiple websites, there should only be one option in there.

6)  Now we need to upload the CertificateSigningRequest.certSigningRequest file we saved to the Desktop in step 2. Click on Create Certificate , and then click on Choose File . Navigate to your Desktop, and select the CertificateSigningRequest.certSigningRequest file. Click Continue.

7) Finally, click the Download button to download your certificate, and save it to your Desktop. It will save a file named website_aps_production.cer to your Desktop.

8) Double click on the website_aps_production.cer file to open it in Keychain Access. If prompted, make sure to select login in dropdown menu, as seen below.

9) In Keychain Access, select the Certificates tab from the sidebar, and locate the certificate we just added. It’s pretty easy to tell which one it is because its expiration date should be exactly one year from today. Right click on the file and select Export Website Push ID .

10) When prompted, make sure to save the Certificates.p12 file to your Desktop. If prompted to password-protect the p12 file, do not enter any password. Just click OK. You will however have to enter your admin password to export and save the p12 file.

With the p12 file now on your Desktop, you may upload it to your push notification service of choice, such as OneSignal, WebPushr, etc.

after upgrading to ventura 13.6.6 login to Teams is impossible and Safari complains about non standard compliant certificates

After upgrading to Ventura 13.6.6 (on an Macbook Pro 14.2 (2017) it's no longer possible to login to Microsoft Teams.

I'm able to choose the account to use, but after a short period of time I always get back to the page where I can select the account to use.

If I try to create a new account - the result is "No Network Connection Please check your network settings and try again. [2604]"

Due to Microsoft Support forums this is because of TLS 1.2 being disabled.

But there's no possibility on a Mac to enable this explicitly, because it's enabled by default since Safari 7 ...

The second strange phenomenon I see is Safari complaining about many non "standard-compliant" certificates and thus rejecting to establish a connection to the website. The certificates themselves are absolutely okay as they were accepted by Safari before the update - and are still accepted by all (i.e. Chrome, Chrome Canary, Firefox, Opera) other browsers after the update ...

Any help on this would be highly appreciated.

Thanks in advance,

MacBook Pro (2017 – 2020)
