  • Can you include the relevant info here? Otherwise it is a link only answer, which could disappear any time.

You can download certs from android device or emulator and then check whether it contains needed root ca

Turn Off Antivirus Or Security Application

Using antivirus on your device may cause this problem sometimes. The antivirus application blocks many websites and the security certificate error is displayed. In this case, you can just disable the application for some time and you will get rid of this problem. Let’s see how to disable the antivirus app.

  • First, go to the setting. Find the application and select the Application manager.

  • Find out the antivirus app. You will see an option disable, and then Press the disable option and go back to the browser.

  • Reload the page and hopefully, you won’t see the certificate issue.

How To Check Trusted Root Certificates Installed On An Android Device

Mobile applications offer us a unique opportunity to go about our daily lives, they also expose us to hackers. Currently, Android has become the most popular operating system in smartphones, which was developed by Google in 2007. Statista projects the number of android users in the US alone to grow to over 133 Million by 2024.

However, mobile application development & usage on android as well as the penetration of smartphones are still increasing exponentially.

Although mobile applications offer us a unique opportunity to go about our daily lives, they also expose us to hackers. Hackers can use vulnerable mobile applications to gain access to users money and sensitive information. There are several mobile application security tips that you can implement to secure your android application.

Implementing an SSL certificate like a code signing certificate is one of the most vital security protocols that an android application should have. Securing after going through the above statistics lets us reveal the role of SSL certificate for android app.

What Root Certificates Can Do & How To Disable Them

Manually installing a new root certificate at the request of an app developer or a website is considered a security risk. These certificates can help the app or service owner to bypass encryption and provide access to the entire web traffic of the user. While trusted root certificates helps detect fraud and other illegal activities by apps, installation of new ones can be used for large-scale data harvesting. Fortunately Android users do have the option to disable certificates if they want. All they need to do is go to settings, select security, choose the ‘trusted credentials’ option from the list and manually disable those certificates that they deem unnecessary.

This change in policy on root certificates will put pressure on other major players like Apple and Microsoft to bring better transparency to their own warnings, access to, and disabling of certificates. Popular browsers with clunky certificate interfaces could also start to act in a similar way with greater informed consent for users. Especially as with encryption getting stronger, root certificates have become a popular tool for those looking to access consumer data, and not just on Android.

Install Der File On Your Android Device


If your device is unable to import the .crt file above, install a .der file.

  • Verify there is screen protection or a PIN code configured on your device.
  • Copy the .der certificate file to the root location of internal storage in your Android device.
  • On your device, tap Settings.
  • Tap Security > Credential Storage > Install from device storage.
  • Type DigicertG2 for the certificate name.

    How Android Trust Anchor Work

    Android comes with a set of preloaded CA root certificates trusted by the system. Users can install new certificates and disable the preloaded CA Certificates from Settings > Security > Trusted Credentials. Users can only install new certificates to the system if the device lock screen security is other than none or swipe to unlock.

    Android has three credential storage mechanisms:

    • Default credential storage
    • VPN and apps credential storage

    How to import CAcert root certificates into browser clients.

    In order to have your browser or system automatically trust all certificates signed by the CAcert Certificate Authority, you must instruct your platform or browser to trust the CAcert root certificate .

    Note that for all systems, you will need to trust both the root certificate root_X0F.crt, as well as the class 3 certificate class3_x14E228.crt.

    Some of this information is already covered in the BrowserClients article, so also look there to see if it has the information you need.

    Trusting a new Certificate Authority is a process that varies from one platform to the next, so here are some of the ways to trust the CAcert root certificates. The instructions below will only outline how to trust one certificate, and just repeat the process to trust the second certificate.

    WARNING: Always double-check the fingerprint on the downloaded certificates before trusting them. If you don’t, you could be trusting a maliciously modified root certificate.

    Why Install Certificates In System Trust Store

    While performing a pentest or doing security research or just want proxy the HTTPS traffic of apps using a proxy tool such as Burp, Zap,mitmproxy All the apps by defaults do not trust the user trust store unless explicitly stated in the network security configuration of the app.

    It is good idea to check this configuration even before attempting to bypass the certificate pinning or else one may end up in a rabbit hole.

    Even if a app does trust the user store in the configuration you may still have trouble proxying all the applications traffic. If the app uses the WebViews for loading any HTTPS web pages in the app they might not be loaded on the app. As the WebViews do not trust the user store even if the app does so.

    Installing the certificate of proxy server in the system store will solve this issues.

    The procedure for installing a certificate will differ from device to device please check the user guide for your specific device. However, the steps should be similar whether you’re installing on Android or iOS.

    You have two methods for getting the exported certificate onto the device:

    • Email the certificate file to an account that you can retrieve on the test device.
    • Tether the device by USB or other cable to the PC onto which you exported the certificate and manually move the file onto the device via Windows Explorer.

    When the certificate file is on the device, attempting to open or access the file typically causes the device OS to recognize it as a certificate, at which point the device prompts you to install the certificate.

    What Trusted Root Cas Are Included In Android By Default

    There doesn’t seem to be a central Android resource that lists the Trusted Root CAs included in the OS or default browser , so how can I find out which are included on my phone by default?

    With the number of root certificates that have been compromised, and the number of fraudulent SSL certs created over the last couple of years, this is an issue for anyone relying on SSL for security, as otherwise you won’t know if you want to remove any trusted CAs.

    • 1I have used this app to list and delete individual root certs: CACertMan or on Play Store. The guradian project also maintains an edited version of the standard keystore: github.com/guardianproject/cacertJul 26, 2012 at 14:02
    • Play Store link in previous comment is wrong – Here’s the right one Play StoreJul 26, 2012 at 14:38

    On ICS or later you can check this in your settings. Go to Settings-> Security-> Trusted Credentials to see a list of all your trusted CAs, separated by whether they were included with the system or installed by the user.

    Earlier versions of Android keep their certs under /system/etc/security in an encrypted bundle named cacerts.bks which you can extract using Bouncy Castle and the keytool program. The summary is to first pull the bundle using adb then you can use Bouncy Castle to list the contents of the bundle:

    Export The Trusted Root Ca Certificate

    To use PKCS, SCEP, and PKCS imported certificates, devices must trust your root Certification Authority. To establish trust, export the Trusted Root CA certificate, and any intermediate or issuing Certification Authority certificates, as a public certificate . You can get these certificates from the issuing CA, or from any device that trusts your issuing CA.

    To export the certificate, refer to the documentation for your Certification Authority. You’ll need to export the public certificate as a DER-encoded .cer file. Don’t export the private key, a .pfx file.

    You’ll use this .cer file when you create trusted certificate profiles to deploy that certificate to your devices.

    • 3saved my life. On “modern” Samsung phones, it’s hidden in Settings -> Biometrics and security -> Other security settings -> Install from device storage -> CA Certificate -> Install Anyway.

    There’s a tiny note about this in the Android 11 enterprise changelog here, which says:

    Note: Apps installed on unmanaged devices or in a device’s personal profile can no longer install CA certificates using createInstallIntent. Instead, users must manually install CA certificates in Settings.

    Sounds very much like this is intentional, and you won’t be able to get around it on normal unmanaged devices. You’ll either need to look into full Android device management, or provide instructions to your users on doing manual setup instead.

    Note that registering your app as a normal device admin app is not sufficient either. To use the remaining DevicePolicyManager.installCaCert API your app must be the owner of the device or profile.

    That means from Android 11+, you can do automatic setup for CA certs used only within separate & isolated work profiles on the device, or for fresh devices that you provision with your app pre-installed, and nothing else.

    Certificate Is Not Trusted On Android

    Dear Letsencrypt Team,

    Recently I faced to a problem – on some of Android devices your certificate is not trusted any more throwing following exception:

    Handshake Exception Handshake error in client )

    Chrome browser on these devices does not recognize the certificate as well but interesting is that on same device Samsungs browser works fine!

    My domain is: www.fellow7000.com

    I ran this command: n/a

    It produced this output: n/a

    My web server is : IIS10 on Windows

    The operating system my web server runs on is : Windows

    My hosting provider, if applicable, is: Mocha Host

    I can login to a root shell on my machine : no

    Im using a control panel to manage my site : Solid CP

    The version of my client is : no idea

    Everything was working fine couple of months ago but now does not any more

    You support will be highly appreciated!

    Thanks in advance!

    Youre sending the intermediate certificate signed by the ISRG Root X1 root certificate in your certificate chain. While this root certificate is accepted in many modern root certificate stores, it isnt in older stores like your old Android versions.

    You should use the intermediate certificate signed by the DST Root CA 3 root certificate from IdenTrust in the document below).

    See for more information.

    Thank you very much for your prompt response!

    As Im nub in SSL stuff, could you please point me how I can install this intermediate certificate while I am on shared hosting at Mocha w/o root access?..

    Why There Is A Security Certificate Error

    A security certificate error is not so much dangerous as people think. Most of the time, it isn’t a problem with your phone. It generally happens because of the corrupted websites or by visiting a website which has some problems. There are some reasons behind this problem, here are those –

    1. Your Android Fails to Communicate

    There is no need to panic because if your Android is unable to obtain the security certificate, then it can be easily fixed. This happens because your date and time aren’t set correctly, or your browser isn’t up to date.

    2. The Website Has Changed

    Sometimes the issue is really simple as it appears because of the maintenance of the website. That could happen if the website was changed from the place where it was hosted or the admin upgraded something, or the admin moved something, any server down problems or anything else. You will see this security certificate error on most of the popular websites. But it should disappear within a minute. If you notice any of these errors in any trusted website, check out if the URL is still the same or not.

    3. A Website is Incorrect or No Longer Safe

    Your Old Android Device Will No Longer Support Many Websites In 2021

    If you have an old Android phone, it may be time to really consider an upgrade.

    According to a report from Android Police, many secure websites will no longer work on devices with Android versions prior to 7.1.1 Nougat. Heres whats happening.

    The certification non-profit organization Lets Encrypt recently announced that its partnership with certification authority IdenTrust will end on Sept. 1, 2021. With no plans to renew, Lets Encrypt is planning to completely switch over to its own root certificate and stop default cross-signaling for IdenTrusts on January 11.

    In layperson’s terms, this means that many secure websites will no longer be compatible with older versions of Android.

    This could end up being a problem. As Lets Encrypt notes, 33.8 percent of Android devices are running these older versions of the operating system. Those devices will experience certificate errors when trying to visit many secure websites starting in 2021.

    So, if you were thinking of updating your old Android device, now might be a good time before it becomes obsolete.

    However, if you dont want to upgrade your phone, you may still have options. Lets Encrypt has recommended that old Android device owners download Firefox and use it for their web browsing needs.

    But fair warning: That could solve the mobile browsing issues for now, but you may still experience certificate errors when using apps on your old Android device, making an upgrade necessary.

    How Can I Be Sure That It Is Authentic

    How to Install Trusted Root SSL Certificate in Mac OSX via the Google Chrome Browser

    There are many ways to ensure that you have an authentic, non-tampered copy of the root certificates, all of which boil down to having a trusted party verify the certificate fingerprints. In some cases, your system distribution is the trusted party, but you can also verify it for yourself.

    • If your system is mentioned above, you can follow those instructions to ensure you have a authentic copy of the CAcert root certificates.

    You can manually download and verify the certificates from here.

    Microsoft Endpoint Manager Support For Android 11

    Android 11 was released by Google on September 8th. Both our App Protection Policy team and our Mobile Device Management team have been testing on Android 11, and wanted to let you know what we have found. All main Intune APP and MDM scenarios are compatible with this latest version of Android, but there are some changes and best practices to be aware of, which we share in the post below.

    Here are a few things youll want to know:

    • Update apps: Encourage your end users to update to the latest version of the Company Portal, Edge, and other APP-supported apps. The latest version will provide the best experience with devices running Android 11.
    • APP and Shared Datasets: Note that requiring encryption by policy will have the following effect on the Shared Datasets introduced with Android 11. If encryption policy Is not required, then Shared Dataset storage will be allowed. If encryption is required by policy, then:
    • For a single-identity app, the blob storage commit will be allowed if the data is private to the app. Otherwise, it will be blocked.
    • For a multi-identity app, the blob storage commit will be blocked.
  • Privacy messaging: Android 11 introduces some user experience changes to increase transparency for users. User may see new messaging, such as additional notifications about app permissions granted by their organization.
  • If the trusted root certificate is on the device, then the SCEP certificate profile will install successfully.
