With minimal credit and regulatory risks involved, they are safe digital payment facilitators that deliver convenient transactions, freedom from debt, and rewards. Banks leverage debit cards for higher customer acquisition, retention, and loyalty while diversifying revenue streams through transaction fees.&nbsp;In India, the number of debit cards in circulation is projected to witness a steady increase of 84.6 million cards by 2028. The total number of debit cards is anticipated to reach an impressive&nbsp;1&nbsp;billion*.<h2 class="heading-node" id="0zxvdvu3r" style="text-align: justify">Need for a Modern Debit Card Solution&nbsp;</h2>Banks today need to keep up with growing customer expectations, advanced technology innovation, and regulatory changes. Though legacy debit card systems have served traditional banks so far, they have limited agility and are high on cost. The restrictions impact their ability to accelerate efficiencies, handle major transaction volumes, and accommodate technology upgrades and innovations. These hinder the bank’s capability to go-to-market quicker with debit cards that support instant upgrades and growth.&nbsp;Investing in a scalable, robust, new-age&nbsp;<a class="link" href="https://m2pfintech.com/blog/say-goodbye-to-hassles-simplify-debit-card-management-with-m2p-fintechs-revolutionary-platform/">debit card management</a>&nbsp;solution that accelerates&nbsp;<a class="link" href="https://m2pfintech.com/blog/debit-card-issuance-101-all-you-need-to-know/">debit card issuance</a>&nbsp;and decreases operational inefficiencies is crucial for banks.

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.

Developers must make sure they follow all these processes while seamlessly communicating the changes with their team members.&nbsp;&nbsp;That’s why development teams across the world practice a mechanism called Continuous Integration (CI) and Continuous Delivery (CD).&nbsp;Starting from generating a build using command line, uploading build to test flight using fast lane, interfacing Jenkins with bitbucket and Fastlane, CICD mechanism can simplify and automate the process of build generation for iOS developers.&nbsp;We are coming up with a 3-part series covering the A-Z of deploying CI/CD mechanism for automating build generation.&nbsp;&nbsp;In this blog, we will be talking about generating a local build using command line.&nbsp;Let’s dive in.&nbsp;This blog is written by <a class="link" href="https://www.linkedin.com/in/ranjith-ravichandran-73829793/">Ranjith Ravichandran</a>, Senior SDE, Product Engineering at M2P.&nbsp;<h2 class="heading-node" id="vixdomkir" style="text-align: justify">What is CI/CD?&nbsp;</h2>Continuous Integration is the practice of merging code changes to a shared repository many times a day. It includes automated building generation and testing. &nbsp;Continuous Delivery is continuous integration with additional processes which allows application release to the customers after each change or update. &nbsp;&nbsp;<h2 class="heading-node" id="gf7yuvxyf" style="text-align: justify">Why CI/CD?&nbsp;</h2>Continuous integration and continuous delivery (CI/CD) is a critical component of agile software development, which emphasizes the importance of delivering working software to users quickly and frequently. This allows stakeholders and users to access newly created features and provide feedback as soon as possible, so features can be iteratively improved.&nbsp;CI/CD is a valuable tool for software developers, regardless of the size of their team. For solo developers, CD may be even more important, as it can help to ensure that software is delivered to users quickly and reliably.&nbsp;In this blog, we will show you the behind the scenes of building, testing, archiving, and uploading an iOS application.

SOLID Principles: A Comprehensive Guide to Object-Oriented Class Design Using Swift

<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-2.webp" alt="M2P Fintech" title="" width="100%" height="370">The microfinance industry has been witnessing stellar growth over the last decade. The sector grew&nbsp;16.5 times, from ₹ 17 thousand crore in 2012 to ₹ 2.85 lakh crore in 2022. With a market share of&nbsp;37.53 %, NBFC-MFIs stand as the leading financial provider in this sector.Thanks to the proven model of&nbsp;Joint Liability Groups (JLGs), the Microfinance Institutions (MFIs) witnessed phenomenal growth in the past decade. This model enabled doorstep access of financial services to the underserved population, mainly women.In addition to the JLG model, the Government of India initiatives listed below have also aided the growth of MFIs.•&nbsp;Pradhan Mantri Jan Dhan Yojana (PMJDY) - This&nbsp;government scheme was the primary reason for millions of Indians to have a bank account.•&nbsp;Jan-Dhan Aadhaar-Mobile (JAM) trinity -&nbsp;Helps Indians to link their Jan Dhan account, Aadhaar card, and Mobile number.•&nbsp;India Stack -&nbsp;Comprises of paperless, cashless, and consent layers that help lenders to collaborate with Fintechs and create products based on customer needs.•&nbsp;Aadhaar Penetration -&nbsp;Aided the shift of the traditional banking system to a digital model for enabling technology players with&nbsp;electronic Know Your Customer (eKYC) and authentication services.<h2 class="heading-node" id="q0wu2iefn" style="text-align: justify">Challenges Amid Growth</h2>The above factors are accelerating the microfinance penetration. But the industry is witnessing cracks due to the challenges in the current model of borrower engagement – the&nbsp;High Touch Model (HTM).In contrast to the&nbsp;Low-Touch Model (LTM), the&nbsp;HTM&nbsp;has high engagement level between the loan officer and the borrower. This may look encouraging from an aerial view. But this model is one of the main reasons for the&nbsp;high attrition rate of the loan officers&nbsp;and the increase in Operational Expenses (OPEX). According to a KPMG report by MFIN, this model does not offer borrowers the necessary value proposition to attend group meetings and maintain group dynamics post-adoption of the cashless collections.This led the <a class="link" href="https://m2pfintech.com/micro-finance/" target="">microfinance</a> players to move towards a more efficient model – the&nbsp;Tech-Touch Model (TTM).<h2 class="heading-node" id="awrgve7ov" style="text-align: justify">Tech-Touch Model – Amalgamation of Low-Touch and High-Touch Models</h2>The Tech-Touch Model strikes a perfect balance between the&nbsp;efficiency and cost savings of a low-touch model and the personalization and support that high-touch model offers. In addition, it is an advanced version, extending the best of both worlds – automation and self-service tools from the low-touch model and customer engagement from the high-touch model.Many MFIs are gradually adopting the tech-touch model to digitize their loan sourcing, management, and collection processes. By leveraging the benefits of the TTM, lenders are on the path to&nbsp;Digital Microfinance.<h2 class="heading-node" id="bxz4bwal3" style="text-align: justify">What does Digital Microfinance Entail?</h2>Digital <a class="link" href="https://m2pfintech.com/blog/how-technology-is-revolutionizing-microfinance-lending/" target="">Microfinance</a>&nbsp;is the hot, new buzzword in the microfinance realm. As the name suggests, it is the use of digital technologies to disburse micro loans to low-income individuals.With TTM at its core, digital microfinance can&nbsp;digitize, automate,&nbsp;and&nbsp;streamline&nbsp;the loan processes such as loan disbursement, loan management, and collections. By digitizing these processes, MFIs can significantly reduce the time and cost associated with traditional loan origination methods.Usually, loan sourcing is the primary step before loan origination. First, the loan officer responsible for loan sourcing goes to the self-help groups and collects the borrower’s details. Then, he collects all the requisite borrower information and takes it to the branch office, consolidates the borrower details, and assesses the borrower's creditworthiness.&nbsp;All these steps can take up to 3 days. Not to forget the vast volume of paperwork they handle.It can be seen that the conventional way of loan sourcing can be time-consuming and inconvenient. That is why it is crucial for MFIs to opt for digital methods and start exercising digital microfinance.<h2 class="heading-node" id="ktaa2g4jl" style="text-align: justify">Digital Microfinance – Road to Productive &amp; Effective Loan Originations</h2><a class="link" href="https://m2pfintech.com/loan-origination-system/" target="">Loan origination</a> is a critical process for lenders. From initial credit assessment, approving/denying loan applications, to disbursing the right loan amount to the right borrower, <a class="link" href="https://m2pfintech.com/blog/top-5-loan-origination-software/" target="">loan origination</a> can be quite tricky. It is even trickier to originate accurate loans in a matter of minutes/seconds.Digital Microfinance accelerates loan originations by employing digital methods for&nbsp;<a class="link" href="https://m2pfintech.com/blog/know-your-customer-kyc-the-need-for-authentication/" target="">KYC</a> verification, bank account verification, borrower credibility check, borrower credit assessment, performing Compulsory Group Training, etc.<h3 class="heading-node" id="7unu5k1rx" style="text-align: justify">Expedite Loan Sourcing via Digitization</h3>With digital tools like our&nbsp;LoanBook application, loan sourcing becomes a piece of cake for the loan officers.Here’s how.The LoanBook application comprehensively digitizes all the work carried out by the loan officer, starting from loan sourcing to management and collections.Using the application, the loan officer adds every member of the JLG into the system along with their details. After entering the basic information, the officer can verify the borrower's details.In<a class="link" href="https://m2pfintech.com/blog/5-key-factors-for-selecting-an-ideal-loan-origination-system-los-partner/" target=""> loan origination,</a> the LoanBook application can help the MFIs expedite the following:<h4 class="heading-node" id="4l1ebhq7t" style="text-align: justify">✔&nbsp;EKYC Verification</h4>EKYC verification for the borrower can be done either by validating their fingerprint or through OTP verification or Iris scan.<h4 class="heading-node" id="mm2hs7a2h" style="text-align: justify">✔&nbsp;Penny Drop Verification</h4>The credibility of the borrower’s bank account is verified by dropping a penny into their bank account.<h4 class="heading-node" id="smh6cnj2g" style="text-align: justify">✔&nbsp;Geo-tagging</h4>At the time of sourcing, the field officers can use this feature to tag the location of the borrowers and the self-help groups (where center meetings are conducted). Geo-tagging also eases the loan collection process by quickly pointing to the borrower's location.After completing eKYC, the loan officer adds the details of the borrower’s family members and specifies the loan amount required by the borrower. This is where our inbuilt Embedded Business Rule Engine (BRE) comes into the picture.With LoanBook, the time taken for loan decisions reduces to 3 minutes from 3 days.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image.webp" alt="M2P Fintech" title="" width="100%" height="467">Many enterprise MFIs are working closely with us and are already on the road to Digital Microfinance. They have simplified their loan origination process, reduced the Turn Around Time (TAT) from weeks to days, and mitigated their OPEX.

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.
