How to Check the Installed Trusted Root Certificates on Android?

Mobile applications give us a unique opportunity to enjoy our daily lives and be exposed to hackers. Android is currently the most popular smartphone operating system, developed by Google in 2007. Statista expects the number of Android users in the United States to exceed 133 million by 2024.

But with the development and use of mobile applications on Android, the penetration of smartphones is increasing rapidly.

While mobile applications give us a unique opportunity to enjoy our daily lives, they also expose us to hackers. Hackers can use vulnerable mobile apps to gain access to consumer funds and confidential information. Here are some mobile app security tips you can follow to keep your Android app safe.

Implementing an SSL certificate as a token signing certificate is one of the most important security protocols an Android application must have. After looking at the locked statistics above, we can reveal the role of SSL Certificate Android.

Why we Secure an Android with an Secure Sockets Layer (SSL) Certificate?


Here are some reasons to get an SSL certified Android app. The code signifies the certificate and the validity of the mobile app.

    1. SSL Certificate for Data Protection
    2. Security to Payment Gateways
    3. Trust

1. SSL Certificate for Data Protection:

The data protection principles enshrined in the Data Protection Act require all data users to take reasonable practical steps to implement appropriate security measures, which should be commensurate with the severity of the potential harm that could result in a security breach.

In order to comply with these criteria and protect user data, you must ensure the following points.

    • All data transmitted is adequately protected by encryption.
    • Encryption strength is enough to counter any potential threat.
    • Encryption is implemented properly to prevent any kind of fraud.

The first step in protecting your mobile application from any security issues is to obtain and install an SSL certificate. Next, we will learn how to secure an Android application with an SSL certificate.

SSL Certificate is a complete encryption protocol that protects application data from malicious intruders. In most cases, the consumer bar don’t think. This blind trust in users makes it the responsibility of developers to do everything in their power to ensure that users’ sensitive data is adequately protected. SSL acts as an insecure shield that protects application data from malicious Protects against forces.

Installing an SSL certificate in your Android app means that the chances of man-in-the-middle attacks and unnecessary noise are very low.

SSL encryption works by converting plain text data to ciphertext. Only the owner of a valid private key can decrypt the data. Because key data has not been decrypted by terrorists and brokers, it is unlikely that they will be able to successfully access the encrypted data.

2. Security to Payment Gateways:

Payment gateways are useful targets for attackers. Similarly, the certificate of secure socket layer should appear on the photo. The certificate protects all bank details, credit card information and debit card information.

If you have a mobile application and payment gateway, you have no choice but to install an SSL certificate. Tell your users it makes sense. Doing so can build brand loyalty and loyalty. Speaking of trust, let’s look at the ultimate reason why your Android application needs SSL certificate.

3. Trust:

Trust is a key factor in determining the success of any business. To do business with you, users need to trust the security of your application. Having an SSL certificate can boost user confidence. So, users can browse your mobile application with confidence.


Now that you know the importance of SSL in your Android application, you may want to install it in your application but you don’t know how to do it. Don’t worry now.

Follow the steps below and you will install the application.

    1. Buy SSL Certificate
    2. Create a Keystore
    3. Load the Keystore into the Mobile Application to Establish a Secure Connection

1. Buy SSL Certificate:

  • The first step in installing an SSL certificate on your application is to purchase an SSL certificate. Here you need to get the right certificate from a trusted CA. It would be nice if you could get all the proofs needed to build a chain of trust. The trust row contains the server header certificate for the original certificate.
  • You can get the SSL certificate from the tree in the original certificate. You can also get the certificate from the publisher’s official website. After receiving the certificates, you need to save them in X6450 Encoded Base 64 format. Please see the code below.

2. Create a Keystore:

  • To create the main storage, you must first download and store the Bouncycastle package in an easily accessible place. At this point, it makes sense to clearly understand how to pronounce a large sequence of musical instruments. You will find the hardware key command in the bin folder of the JRE installer.
  • You will then need to import the recovered SSL certificate into Bouncycastle format storage. Remember that recommendation is not the last point I want to make. By importing the certificate, I recommend starting with the lowest intermediate certificate of the CA root certificate. Then you need to execute the following command.

Main tool-importcert -v -trustcacerts -file
“Path_to_cert / interm_ca.cer” – Also called IntermediateCA
– Provide keystore “res / raw / myKeystore.bks”
org.bouncycastle.jce. Resources.bouncyCastle
-Near road “Bouncing Castle / bcprov-jdk16-145.jar”
BKS -storepass mysecret

  • Similarly, you need to verify that the certificate has been properly transferred to the main repository. Under RES you can easily copy K-storage to your mobile application.

3. Load the Keystore into the Mobile Application to Establish a Secure Connection:

The last step is to create an Apache Http Client that uses the same token to establish a secure Hypertext Transfer Protocol (HTPSPS) connection.

My Http Client Default Http Client(final context; My Http Client public(context) { this. context = context;} @unexpect Client Connection Manager create Client Connection Manager(“// Register our SSL Socket Factory key port for port 443 // Connection Manager Registry. Register (new scheme (“https”, new Ssl Socket Factory () 443)); Bring back new clients (get Programs (), registry); Try} new SSL Socket Factory new Ssl Socket Factory () {// Bounce Castle Key store Format Key store Trust = Key Store. get Instance (“BKS”); Try: // Find the raw material with the trust certificate key (Root and all intermediate certificates) Input Stream = Context. get Resources (). open Raw Resource (R. raw. my key store); Visit {// Replace key store with trusted certificate // and enter secure key store password. “my secret” (.to Char Array ();} end {in. close (); // Send the token to SSL Socket Factory. Factory Responsible // Server certificate. SSL Socket Factory sf = new SSL Socket Factory (trusted); // Verify Certificate Hostname // sf. set Host name Verifier (SSL Socket Factory. Back to STRICT_HOSTNAME_V; variable; SF) {New Certificate Error (E);

After completing this step, you have successfully created a custom Http Client to encrypt application data.
