Safeguarding mobile app information from unauthorized access is imperative to prevent cyber-attacks.&nbsp;<h2 class="heading-node" id="iptpr69rj" style="text-align: justify">AES and ECDH&nbsp;</h2>To address security challenges, advanced encryption and decryption mechanisms must be integrated into the Android applications. By implementing robust encryption algorithms such as AES (Advanced Encryption Standard), and incorporating secure key exchange protocols like the Elliptic Curve Diffie-Hellman (ECDH) algorithm, developers can fortify their apps against potential breaches. &nbsp;The ECDH algorithm ensures sensitive data is protected from unauthorized access, enhancing the overall security of applications. This advanced process creates a trusted and secure environment for seamless data transmission. &nbsp;In this blog, our Code Specialist and Lead Software Development Engineer <a class="link" href="https://www.linkedin.com/in/janarthanan-radhakrishnan-b6933b118">Janarthanan</a>, will guide you through the intricate world of encryption and decryption logic using AES. With his expertise, you can understand how this cutting-edge technology seamlessly integrates into the Android app, providing a robust shield for sensitive data with utmost ease and efficiency.&nbsp;To start off, let’s understand cryptographic algorithms. &nbsp;<h2 class="heading-node" id="wb39lawnc" style="text-align: justify">What is a Cryptographic Algorithm?&nbsp;</h2>Cryptographic algorithms (also known as encryption algorithms) are mathematical formulas that define how the encryption and decryption processes are carried out. They define specific steps and operations involved in transforming the data and play a crucial role in the security of encryption systems. The figure below depicts the processes of encryption and decryption, which work together to ensure the confidentiality and integrity of data. &nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/Blog-02-1.webp" alt="M2P Fintech" title="" width="100%" height="531">Cryptographic algorithms significantly impact the level of security, performance, and compatibility of the encryption and decryption processes. Now, let's explore AES algorithms, our superhero of data security.<h2 class="heading-node" id="foloj6te0" style="text-align: justify">Advanced Encryption Standard (AES)&nbsp;</h2>AES acts as a powerful shield that ensures personal data remains confidential and protected. It is commonly used to secure sensitive data such as credit card numbers, passwords, and personal data. It is also used in different applications, including SSL/TLS encryption for web traffic, disk encryption, and email encryption.Let’s explore the different modes of AES.&nbsp;<h3 class="heading-node" id="bkmq1255i" style="text-align: justify">Modes of AES&nbsp;</h3>When it comes to securing data with Advanced Encryption Standard, different modes can be used. Each mode offers unique characteristics and serves specific purposes in securing sensitive data. &nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/Blog-03-1.webp" alt="M2P Fintech" title="" width="100%" height="531">Let’s briefly look at each of the modes before into AES implementation.&nbsp;<h4 class="heading-node" id="f2ir19hck" style="text-align: justify">Electronic Code Book (ECB)&nbsp;</h4>Electronic Code Book (ECB) mode independently encrypts fixed-size blocks of plaintext using the same key, which can lead to vulnerabilities. It is not suitable for encrypting large amounts of data or high-security scenarios. Therefore, it is generally not recommended for most encryption purposes.&nbsp;<h4 class="heading-node" id="t63ath78e" style="text-align: justify">Cipher Block Chaining (CBC)&nbsp;</h4>Cipher Block Chaining (CBC) mode enhances security by incorporating an Initialization Vector (IV). The IV is the same size as the encrypted block and adds an element of randomness to the encryption process. To ensure cryptographic security, each encryption of the same plaintext should produce a different ciphertext.&nbsp;<h4 class="heading-node" id="nh0hghn4a" style="text-align: justify">Cipher Feedback (CFB)&nbsp;</h4>The Cipher Feedback (CFB) mode of operation can use a block encryptor as a stream cipher. Like other modes, it requires an initialization vector (IV). In CFB mode, the IV is first encrypted and then XORed with the plaintext block to generate the corresponding ciphertext. This process is repeated for each subsequent block, where the previous encryption result is encrypted and XORed with the next plaintext block.&nbsp;<h4 class="heading-node" id="fx050wp5g" style="text-align: justify">Output Feedback (OFB)&nbsp;</h4>The Output Feedback (OFB) mode of operation allows a block encryptor to function as a stream encryptor without requiring any padding data. In OFB mode, the initialization vector (IV) is encrypted initially, and the resulting encryption is then used to XOR with the plaintext to generate the corresponding ciphertext. This process is repeated for each subsequent block, where the previous encryption results are continuously encrypted and XORed with the next plaintext block. Additionally, the encryption and decryption of the IV cannot be performed in parallel in this mode.&nbsp;<h4 class="heading-node" id="mz2y4f5r9" style="text-align: justify">Counter (CTR)&nbsp;</h4>The Counter (CTR) mode of operation uses a counter as the input block for the encryptor. The counter is of the same size as the block being used. In CTR mode, the encryptor generates a keystream by encrypting the counter value using the encryption key. This keystream is then XORed with the corresponding plaintext block to produce the ciphertext. Importantly, each encryption block in CTR mode utilizes the same encryption key, ensuring consistency throughout the encryption process.&nbsp;<h4 class="heading-node" id="xlyf8ecqs" style="text-align: justify">Galois Counter Mode (GCM)</h4>The Galois Counter Mode (GCM) is a powerful encryption mode that combines the Counter (CTR) mode with authentication mechanisms. It offers enhanced speed and security thanks to its efficient implementation of table-driven field operations. GCM is primarily used for authenticated encryption, providing confidentiality and authenticity for the encrypted data. It also ensures authenticity for the additional authenticated data (AAD) associated with the encrypted data. It's important to note that the AAD is not encrypted but still benefits from the authentication mechanisms provided by GCM.&nbsp;When it comes to client-server communication, it is essential to prioritize security. Hackers can easily exploit simple requests during transmission. Let us now look at code implementation in GCM.&nbsp;<h3 class="heading-node" id="wphhfliz1" style="text-align: justify">Code Implementation Steps in GCM&nbsp; &nbsp;&nbsp;</h3>When implementing the code, the first step is to Open Android Studio. Once we have Android Studio up and running, the next step is to set up the Gradle build system.&nbsp;&nbsp;<h4 class="heading-node" id="452izau5l" style="text-align: justify">Gradle Setup&nbsp;</h4>Gradle is an essential component that helps manage dependencies and build configurations for our Android app.&nbsp;In the Gradle first, the Spongy Castle dependency file is added in the build. Gradle. &nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-30.webp" alt="M2P Fintech" title="" width="100%" height="194">Let’s see the steps involved!&nbsp;&nbsp;<h4 class="heading-node" id="7780raqib" style="text-align: justify">Step 1: Generate Key Pair&nbsp;</h4>The first step is to generate the Key Pair.&nbsp;&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-36.webp" alt="M2P Fintech" title="" width="100%" height="276"><h4 class="heading-node" id="7rg6q5jxl" style="text-align: justify">Step 2: Generate Private Key&nbsp;</h4>The private key in cryptography is called symmetrical because it involves a single secret key for encryption and decryption. Compared to public-key cryptography, which involves two separate keys (public and private), the symmetrical approach offers faster encryption and decryption processes. To ensure secure communication, both the sender and receiver must possess and use the same private key, making it a crucial component in algorithms like AES 128, AES 192, and AES 256, which enhance the overall robustness of data encryption and decryption. &nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-37.webp" alt="M2P Fintech" title="" width="100%" height="164"><h4 class="heading-node" id="qx6vhhl7v" style="text-align: justify">Step 3: Generate Public Key&nbsp;</h4>The public key in cryptography operates on an asymmetrical principle as it involves two distinct keys: private and public keys. Unlike the private key, the public key is used for encryption, while the private key is used for decryption. Due to its inherent nature, public key cryptography tends to be slower than symmetrical private key cryptography. Algorithms like RSA, DSA, and others use the public key for secure encryption processes, ensuring the confidentiality and integrity of data.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-32.webp" alt="M2P Fintech" title="" width="100%" height="130"><h4 class="heading-node" id="85zwautk9" style="text-align: justify">Step 4: Need Exchange Server Public Key&nbsp;</h4>To establish secure communication with a web service, it is essential to transmit our public key. Once the web service validates the received public key, it will respond by providing its own public key. This server public key is crucial in generating a secret key for further cryptographic operations. &nbsp;<h4 class="heading-node" id="26qgwpzzk" style="text-align: justify">Step 5: Generate Secret Key before Data Encryption&nbsp;&nbsp;</h4>In secret key encryption, the key used for encryption and decryption remains the same. As a result, ensuring the proper safeguarding and distribution of this key becomes crucial.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-33.webp" alt="M2P Fintech" title="" width="100%" height="287"><h4 class="heading-node" id="n2pai8z03" style="text-align: justify">Step 6:&nbsp; Encrypt the Data&nbsp; </h4>Encryption is a crucial process in data security, transforming a normal message (plaintext) into a meaningless form (ciphertext). Its primary objective is to convert plain text into a complex and unreadable format, ensuring that the original message becomes inaccessible to anyone without the decryption key. The output of encryption is a ciphertext, which appears as a series of scrambled characters to unauthorized individuals.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-34.webp" alt="M2P Fintech" title="" width="100%" height="403"><h4 class="heading-node" id="kcla3xod4" style="text-align: justify">Step 7:&nbsp; Decrypt the Data&nbsp;</h4>Decryption plays a vital role in data security by reversing the encryption process and converting a meaningless message (ciphertext) back into its original form (plaintext). Its primary objective is to convert the cipher text into plain text. Decryption reverses the encryption process and converts the ciphertext back into plaintext.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/07/MicrosoftTeams-image-35.webp" alt="M2P Fintech" title="" width="100%" height="382">The integration of encryption and decryption logic using AES in Android apps has ushered in a new era of data security and confidentiality.

How to Secure an Android App with AES

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-10.webp" alt="M2P Fintech" title="" id="69sc202tm" width="100%" height="317">Great <a class="link" href="https://m2pfintech.com/blog/elevating-b2b-experience-design/">experience design</a> is vital to drive customer loyalty and revenue. User Interfaces are crucial components that enable enhanced customer experience.Building an Android User Interface (UI) is not an easy task. XML layouts can be verbose and difficult to maintain. And it can be hard to make changes to the look and feel of the <a class="link" href="https://m2pfintech.com/blog/super-apps-in-consumer-banking-what-role-does-open-banking-play/">mobile app</a> without rewriting layouts. Many developers still grapple with complexities in XML layouts, code volumes, and spend hours on tedious UI updates.Is there a way you can build better Android UIs with less code?Jetpack Compose holds the answer.In this blog, our resident Android Expert and Software Development Engineer <a class="link" href="https://www.linkedin.com/in/sagarbalyan/">Sagar Balyan</a> explains what Jetpack Compose is, its benefits, and how it is transforming Android UI development by overcoming the limitations of the traditional approach.<h2 class="heading-node" id="9sz77xr8f" style="text-align: justify">What is Jetpack Compose?</h2>Jetpack Compose is the cutting-edge toolkit for building native UI in Android. It simplifies and speeds up UI development allowing you to bring your apps to life with minimal code, a robust set of tools, and user-friendly Kotlin <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">API</a>s.Jetpack Compose is declarative, meaning you can describe how your UI should look like, rather than how it should be built, making it much easier to create complex layouts with maintainable code. Its speed and ease of use have quickly made it the preferred choice of technology for Android development.Now, let’s explore the benefits that Jetpack Compose brings to the table.<h3 class="heading-node" id="0fkwz62xu" style="text-align: justify">Less Code</h3>Less code is the new norm, thanks to Jetpack Compose. By eliminating XML files, it simplifies the development process and eliminates unnecessary complexity. It's no wonder that even Twitter has applauded its low code feature, highlighting how the code required for a Button class was dramatically reduced by 10X.<h3 class="heading-node" id="neh0tnq7w" style="text-align: justify">Faster Development</h3>Jetpack Compose not only accelerates the Android app development process but also makes it faster and more efficient. With its intuitive and declarative syntax, developers can build user interfaces in a fraction of the time compared to traditional approaches. Additionally, Jetpack Compose simplifies the implementation of light and dark modes in apps, making it easier to create visually appealing and consistent experiences across different themes.<h3 class="heading-node" id="qcy4oaro2" style="text-align: justify">Live Previews</h3>Jetpack Compose can provide live previews and is not just limited to just one. Developers can create and preview multiple composables live previews in real-time, allowing for seamless experimentation and instant visual feedback. This powerful feature enables developers to iterate and refine their UI components quickly, leading to more efficient and effective development cycles.<h3 class="heading-node" id="qbozuvyso" style="text-align: justify">Powerful</h3>Jetpack Compose can help you build stunning apps by providing direct access to the Android platform APIs and seamless integration with essential features like material design, dark theme, and animations. This powerful toolkit has garnered the attention of industry leaders like Square, who have declared that Compose goes beyond just offering a declarative UI. It has significantly improved accessibility APIs, layout capabilities, and various other aspects of app development.<h3 class="heading-node" id="8gshymfhu" style="text-align: justify">Separation of Concern</h3>Other than these benefits, Jetpack Compose addresses a barrier that was present in the traditional XML approach namely the Separation of Concern. For example, when a Viewmodel was written in Kotlin, it had a close interaction with the XML file. This tight coupling between the Viewmodel and the XML file caused increased dependencies.If these components are tightly coupled and heavily dependent on each other, it defeats the purpose of having two separate files. However, Jetpack Compose resolves this problem by allowing the UI to be written directly in Kotlin. This means that the Viewmodel and the UI are now seamlessly integrated, reducing dependencies and enhancing code organization. With Jetpack Compose, developers can achieve a more cohesive and efficient development workflow.Due to these wide-ranging benefits, more companies are transitioning from the traditional XML approach and embracing this modern toolkit.<h3 class="heading-node" id="hzgcqsw3y" style="text-align: justify">Live Jetpack Compose Apps</h3>Wonder what live apps have been built on Jetpack Compose?Here are a few.

How to Create Stunning UIs for Android with Jetpack Compose

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/04/Penetration-testing-banner1.webp" alt="M2P Fintech" title="" width="100%" height="253">The $158.9 billion fintech industry thrives on mobile apps. Android dominates the mobile app market with a whopping 71.65% market share. Though in demand globally, its open-source&nbsp;nature makes data security a vulnerability in Android apps. Even <a class="link" href="https://m2pfintech.com/blog/super-apps-in-consumer-banking-what-role-does-open-banking-play/">super apps</a> are no exception.&nbsp;Developing and releasing a fully functional and secure Android application is a critical challenge for app developers. Managing app functionality is the easy part; but the real challenge is making the Android application secure and resilient to cyberattacks. &nbsp;What’s the best way to do this?&nbsp;Our Software Development Engineer, <a class="link" href="https://www.linkedin.com/in/sundaramanikandan-l-80957014b/">Sundaramanikandan</a> has hands-on experience in developing highly secure Android apps and will take us through every step in mitigating cyberattacks while developing an app. &nbsp;First things first, every developer must prioritize security to protect users and their data. The security-first approach will benefit the 6.92 billion smartphone users in the world, who constitute over 86.29% of the global population.&nbsp;&nbsp;Remember that the advances in digitization and technology also apply to hackers and cybercriminals. Technology that makes lives easier has increased our exposure to risks. Fraudsters ride on the vulnerabilities by using more sophisticated techniques to exploit loopholes and evade detection while breaking into systems to access sensitive data.&nbsp;<h2 class="heading-node" id="sdulm87wi" style="text-align: justify">How to secure Android devices from attackers?&nbsp;</h2>Developers and organizations need to deploy secure software development lifecycle practices to protect against data breaches or theft. Public Wi-Fi networks and other wireless communication systems should be blocked to prevent man-in-the-middle attacks and other unsecured communication exploits. Attackers can pretend to be real web services, steal data, or listen in on calls and texts by taking over a user's mobile signal.&nbsp;<h2 class="heading-node" id="d5lk42h71" style="text-align: justify">Smartphone rooting to get superuser permissions&nbsp;&nbsp;&nbsp;</h2>Firstly, the process called rooting is done, i.e., removing the limitations on a mobile or tablet running the Android operating system. It lets you get root access to the code of the Android operating system (the equivalent term for Apple devices is jailbreaking). It gives permission to change the device's software code or install software that the manufacturer wouldn't normally let us do.&nbsp;<h2 class="heading-node" id="oj87o5xpb" style="text-align: justify">Cons of running apps on a rooted device&nbsp;</h2>Simply put, it opens higher risks like spoofing, cheating, and abuse of core functionalities. A root-level app can easily set up backdoors that let unauthorized users get into the device and then into the secure corporate network. When you "root" your Android device, you give apps unauthorized access to your operating system and sensitive data. It further leads to the theft of user data, finances, intellectual property, and piracy. Some malware apps specifically go after rooted devices to infect system-level files. So, you must be careful what you install.&nbsp;Targeted cyberattacks on corporates are on the rise as more and more business transactions are done on mobile devices. Rooted Android devices make it easier to sneak into the corporate network. For a financial app, if an attacker can intercept a network call and change the address, the victim could lose a lot of money, and the company that developed the app will lose its reputation.&nbsp;As having a user-friendly mobile app is a key differentiator, banks and financial institutions are in a dilemma to choose between allowing their app, which contains excellent payment functionalities and extremely sensitive data, to run on rooted/jailbroken devices or risk losing their target audience. Or they can opt for the middle ground by mitigating the risks of the app running on rooted devices. This compromise is critical. Or else, risks such as malware, man-in-the-middle attacks, and system API hijacking could lead to user data exfiltration. &nbsp;Therefore, Android app installation must be blocked on rooted devices to prevent attacks specifically targeting users who have rooted their smartphones.&nbsp;<h2 class="heading-node" id="78wzaxox3" style="text-align: justify">How can app developers block Android installation on a rooted device?&nbsp;</h2>Every Android app developer should understand the following pointers below to steer clear of the hazards of rooted devices.&nbsp; What’s the common way an app can be tampered with?&nbsp;<ol class="list-node" id="lwmuzqjzn"><li>ByPassing root detection logic implemented&nbsp;&nbsp;</li><li>ByPassing the SSL Pinning&nbsp;</li></ol>What are the commonly used hacking tools?&nbsp;<ol class="list-node" id="tym0kml1c"><li>Magisk&nbsp;</li><li>LSXposed Framework&nbsp;</li></ol>Dos and Don’ts - for infosec clearance to block Android app installation&nbsp;Don’ts&nbsp;❌ Install the app on a rooted device&nbsp;❌ Tapjack&nbsp;❌ Copy/paste sensitive data&nbsp;❌ Take screenshots&nbsp;&nbsp;Dos&nbsp;Now, the following method will help create the most comprehensive approach:&nbsp;✅ Check if the app is running in emulator&nbsp;This is the first thing we need to look at when the app is launched. If a hacker extracts the APK and tries to run it in an emulator/simulator, we should stop running the app if it is a production version.

}&nbsp;

✅ Check developer options&nbsp;

Hooking an app is as simple as enabling the developer settings on the device and connecting to the Android SDK tool. Hence, when the app is launched, we must determine whether the developer option is enabled or not by writing an extension function.&nbsp;

fun isDevMode(context: Context): Boolean {&nbsp;
&nbsp;&nbsp;&nbsp; return when {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Build.VERSION.SDK_INT &gt; Build.VERSION_CODES.JELLY_BEAN -&gt; {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.getInt(&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; context.contentResolver,&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Global.DEVELOPMENT_SETTINGS_ENABLED, 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ) != 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Build.VERSION.SDK_INT == Build.VERSION_CODES.JELLY_BEAN -&gt; {&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @Suppress(“DEPRECATION”)&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.getInt(&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; context.contentResolver,&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ) != 0&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; else -&gt; false&nbsp;
&nbsp;&nbsp;&nbsp; }&nbsp;
}&nbsp;

✅ Check if the device is rooted&nbsp;&nbsp;

The Util class is commonly used to determine whether a device is rooted, or the super user “SU” is enabled.&nbsp;

private val binaryPaths = arrayOf(
&nbsp;&nbsp;&nbsp; “/data/local/”,
&nbsp;&nbsp;&nbsp; “/data/local/bin/”,
&nbsp;&nbsp;&nbsp; “/data/local/tmp/”,
&nbsp;&nbsp;&nbsp; “/data/local/xbin/”,
&nbsp;&nbsp;&nbsp; “/sbin/”,
&nbsp;&nbsp;&nbsp; “/su/bin/”,
&nbsp;&nbsp;&nbsp; “/system/bin/”,
&nbsp;&nbsp;&nbsp; “/system/bin/.ext/”,
&nbsp;&nbsp;&nbsp; “/system/bin/failsafe/”,
&nbsp;&nbsp;&nbsp; “/system/sd/xbin/”,
&nbsp;&nbsp;&nbsp; “/system/usr/we-need-root/”,
&nbsp;&nbsp;&nbsp; “/system/xbin/”,
&nbsp;&nbsp;&nbsp; “/system/app/Superuser.apk”,
&nbsp;&nbsp;&nbsp; “/cache”,
&nbsp;&nbsp;&nbsp; “/data”,
&nbsp;&nbsp;&nbsp; “/dev”,

&nbsp;&nbsp;&nbsp; “/sbin/su”,
&nbsp;&nbsp;&nbsp; “/system/bin/su”,
&nbsp;&nbsp;&nbsp; “/system/xbin/su”,
&nbsp;&nbsp;&nbsp; “/data/local/xbin/su”,
&nbsp;&nbsp;&nbsp; “/data/local/bin/su”,
&nbsp;&nbsp;&nbsp; “/system/sd/xbin/su”,
&nbsp;&nbsp;&nbsp; “/system/bin/failsafe/su”,
&nbsp;&nbsp;&nbsp; “/data/local/su”,
&nbsp;&nbsp;&nbsp; “/su/bin/su”,
&nbsp;&nbsp;&nbsp; “./frida-server”,
&nbsp;&nbsp;&nbsp; “/data/local/tmp/frida-server”

)&nbsp;

&nbsp;When this class is called upon app launch, it checks to see whether any of the aforementioned binaries are present on the device and returns “rooted” if any are.&nbsp;

✅ Integrate root detection library like RootBear&nbsp;

RootBear is a popular open-source library that can be utilized in our app to detect root causes.&nbsp;

implementation ‘com.scottyab:rootbeer-lib:0.1.0′&nbsp;

After adding this library in the app build Gradle file, it can be implemented in a base activity like:&nbsp;

if (!BuildConfig.DEBUG &amp;&amp; rootBeer.isRooted) {
&nbsp;&nbsp;&nbsp; showRootedDeviceDialog(getString(R.string.device_rooted))
&nbsp;&nbsp;&nbsp; isRootedDeviceBool = true
} else if (!BuildConfig.DEBUG &amp;&amp; rootBeer.isRootedWithBusyBoxCheck) {
&nbsp;&nbsp;&nbsp; showRootedDeviceDialog(getString(R.string.device_rooted))
&nbsp;&nbsp;&nbsp; isRootedDeviceBool = true
}&nbsp;&nbsp; 
</code></pre>Now, all the steps discussed around a great way to prevent an Android app from being installed or functioning on a rooted device. &nbsp;But this is not all. There is more.&nbsp;There is another tool called ‘Frida’ that helps bypass all the above logics implemented in an app.&nbsp;Want to know how to block Frida?&nbsp;Stay tuned to our next blog!&nbsp;This article is authored by&nbsp;<a class="link" href="https://www.linkedin.com/in/sundaramanikandan-l-80957014b/">Sundaramanikandan.</a><a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://m2pfintech.com/newsletter/" target="_blank" rel="noreferrer noopener">Subscribe</a>&nbsp;to our newsletter and get the latest fintech news, views, and insights, directly to your inbox.Follow us on&nbsp;<a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://www.linkedin.com/company/m2pfintech/mycompany/" target="_blank" rel="noreferrer noopener">LinkedIn</a>&nbsp;and&nbsp;<a class="link fui-Link ___1qmgydl f3rmtva f1ewtqcl fyind8e f1k6fduh f1w7gpdv fk6fouc fjoy568 figsok6 f1hu3pq6 f11qmguv f19f4twv f1tyq0we f1g0x7ka fhxju0i f1qch9an f1cnd47f fqv5qza f1vmzxwi f1o700av f13mvf36 f1cmlufx f9n3di6 f1ids18y f1tx3yz7 f1deo86v f1eh06m1 f1iescvh ftqa4ok f2hkw1w fhgqx19 f1olyrje f1p93eir f1h8hb77 f1x7u7e9 f10aw75t fsle3fq" href="https://twitter.com/m2pfintech" target="_blank" rel="noreferrer noopener">Twitter</a>&nbsp;for insightful fintech tales curated for curious minds like you.

It has radically simplified financial services and processes with the help of banking applications. Back in the day fintech applications were confined only to tech-savvy users, but today, it has become an integral part of life for all generations. The appetite for mobile-first, customized financial applications is driving fintech companies to innovate and consistently deliver advanced products and services.Banking applications are traditionally built for specific operating systems and <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a> using the respective native programming languages/technologies. But these practices resulted in higher cost implications and prolonged time to market. To overcome such limitations, fintechs adopted the latest digital innovations to power personalization, user engagement, and security.The launch of Flutter in 2017 changed the dynamics of application development as it provided a great user experience tailored for specific operating systems. This unique feature made Flutter the holy grail of fintech app development. Over the last few years, several companies have successfully launched their applications using the Flutter framework.Curious to know how to add a flutter module to an existing android and iOS application?You’re in luck. We have our domain expert and Senior Software Engineer,&nbsp;<a class="link au lh" href="https://www.linkedin.com/in/chinnadurai-viswanathan-b2b6b7a5/" target="_blank" rel="noopener ugc nofollow">Chinnadurai Viswanathan</a>&nbsp;share the nitty-gritty of how Flutter can be used in fintech applications.Here are the topics he sheds light upon.<a class="link" href="#430e">What is Flutter?</a><a class="link" href="#d14a">Why Flutter is critical to Fintech?</a><a class="link" href="#fb14">How to Generate a Flutter Module?</a><a class="link" href="#69a3">Android Integrations</a><a class="link" href="#af8c">IOS Integrations</a>Here you go!<h2 class="heading-node" id="ag0mm47r9">What is Flutter?</h2>Flutter is an open-source software development kit from Google. It is used to build cross-platform applications, including mobile, web, and embedded products &amp; services. Programmers employing Flutter write a single codebase to create applications that run across various platforms such as android, iOS, Windows, and Linux. Developers build a Flutter app once and cross-compile them for multiple platforms with Flutter instead of creating an individual application for each platform.Let us be clear here that Flutter is not a programming language. It is a User Interface (UI) framework that works on the Dart programming language. It uses native UI elements which can be personalized during development. Some of the most used Flutter applications are Google Pay, Xianyu by Alibaba, and the KenKen puzzle app.<h2 class="heading-node" id="d14a">Why is Flutter critical to Fintech?</h2>Flutter combines the best features from native and hybrid application development approaches. Therefore, it is considered an optimal solution for neo banks and fintech companies. The Flutter framework offers manifold benefits to the user. But in this article, we emphasize the ones that are most essential for developing a fintech or mobile banking solution. Application and Data SecurityFlutter is powered by Dart and compiled into a native, computer-executable code. There are no intermediary apps required. This makes Flutter-based banking apps more secure than native solutions. Moreover, it also involves a comprehensive native library and changes data formats during compilation. So, the reverse engineering process is multifaceted, making it almost impossible for hackers to comprehend the software functionality to reproduce.Information security and compliance with regulations like <a class="link" href="https://m2pfintech.com/blog/pci-dss-the-payments-armour/">PCI DSS</a> and GDPR are imperative for a banking application. The framework allows biometric authentication via Face ID or Touch ID, and enables Dart developers to leverage the recently released library implementations of all popular data encryption algorithms. This boosts the security of the customers’ personal and financial data as well as transaction details.Reliable PerformanceAn application’s performance is directly proportional to customer engagement and retention rate. Delays in loading time significantly impact the product’s performance, which can make the customers stop using the application again.Flutter can offer up to 120 frames per second (FPS) performance, making it a top choice for banking apps that serve a colossal userbase with rapid response time.Use of Declarative APIFlutter harnesses reactive declarative UI <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a>. This means Flutter’s user interface reflects the current state of the application. For example, if a user flips a switch in the settings screen, it triggers a redraw of the current state, and the UI rebuilds from scratch. This is the key advantage of Flutter.There is only one code path for any state of the user interface. The developer describes what the UI should be like, for any given state once, and that is it. The framework handles the arduous, error-prone task of optimizing the UI.Saves Time, Cost, and EffortUnlike native technologies, the Flutter framework presents a unique feature called the&nbsp;Hot Reload. It allows the developers to see the front-end and back-end changes in real-time. This enhances the product delivery speed as it saves a lot of time involved in developing and compiling a banking app. Additionally, Flutter offers a lot of widgets that help in simulating the behavior of various design languages, thus enabling the developers to jump some of the tedious steps in the application development.Furthermore, by using Flutter, developers write only one codebase for different operating systems. Thus multiple teams for each operating system is not required. This reduces the time and effort involved in testing bugs and potential issues. Furthermore, the use of a single codebase for different platforms drastically alleviates the maintenance process and, in turn, minimizes operational costs.Delivers Seamless User Experience and PerformanceReleasing new features and updates according to end-user feedback is the key to boosting customer engagement and retention. Flutter is flexible and has an in-built application builder. The developers can take advantage of a wide range of pre-developed, reusable UI elements to customize and fit customer needs and specifications. The apps built using this framework facilitate seamless user experience and superior performance.<h2 class="heading-node" id="fb14">How to Generate a Flutter Module?</h2>To create a flutter project, you require one of the following channels: beta, dev, or master.
