Ever wondered how your credit card details stay secure when you make online transactions? 💳🔒 Behind the scenes, a powerful algorithm called JSON Web Encryption (JWE) makes sure your sensitive data remains safe as it travels from your device to the server. Here’s a simple breakdown of how it works! 🌐✨ 🔹 The Process: Imagine three key parts to this process. 1️⃣ Sensitive Data (Payload): This is the information from your card, like your card number, that needs to reach the server safely. 2️⃣ Public Key: This is a special key on your device that plays a role in encoding your information. 3️⃣ Private Key: A unique key on the server that can decode the information. 🔹 How It Works: 1️⃣First, your device generates a unique encryption key (let's call it the Content Encryption Key). 2️⃣This encryption key is secured with the Public Key and then used to encode your sensitive data (the payload). 3️⃣The encoded data, along with an Authentication Tag (AT), is sent over the network to the server. The AT ensures that the data remains untampered in transit. 4️⃣Once received, the server uses the Private Key to decode the encrypted data. The server can do this because it holds the matching key that can unlock the encryption. Only the server has the right keys to view your sensitive information. Meanwhile, the Authentication Tag confirms that the data hasn’t been altered on the way, so you can be sure your information arrives securely and intact. 🔐 This smart encryption keeps your details safe, giving you peace of mind with every transaction! 🌍💼 #DataSecurity #CyberSecurity #Encryption #Privacy #OnlinePayments #DataProtection #CyberSafety #SecureTransactions #JSONWebEncryption #TechSimplified #DigitalSecurity #TechInnovation

🔐 Understanding Open Authorization (OAuth) 🔐 In today's digital age, safeguarding personal information is paramount. One key technology enabling secure access to online services is Open Authorization, commonly known as OAuth. What is OAuth? OAuth is an open standard protocol that allows third-party services to access user data without exposing their credentials. It provides a secure framework for authorization, allowing users to grant limited access to their resources stored on one site to another site, without sharing their passwords. How does OAuth work? When you log in to a website or app using your Google, Facebook, or Twitter account, you're likely using OAuth. Here's how it works: You're redirected to the service you want to use. You're prompted to grant permission to access your data. If you approve, the service receives a token that allows it to access specific resources on your behalf. Why is OAuth important? OAuth enhances security by eliminating the need for users to share their passwords with third-party services. It also provides a seamless user experience, enabling convenient access to multiple services without the hassle of creating and managing separate accounts. In summary, OAuth plays a crucial role in ensuring secure access to online services while protecting user privacy. Understanding its principles empowers users to make informed decisions about granting access to their data. #OAuth #CyberSecurity #OnlinePrivacy #TechnologyExplained

Hi Everyone!! 🔍 HTTP vs HTTPS: What's the Difference? 🔒 When we browse the web, we often see URLs starting with either HTTP or HTTPS. Here's a quick breakdown of what they mean and why HTTPS is the way to go! 🌐 HTTP (HyperText Transfer Protocol) Unsecured - Data is sent as plain text, making it vulnerable to eavesdropping 📂 No Encryption - Attackers can intercept and view sensitive information 😬 Common on non-sensitive sites where security isn’t a primary concern 📖 🔐 HTTPS (HyperText Transfer Protocol Secure) Secured with SSL/TLS - Encrypts the data, protecting it from prying eyes 🔑 Trusted - HTTPS sites often display a padlock symbol, giving users confidence in site security 🛡️ Required for sensitive transactions like payments, personal data entry, etc. 💳 👉 Takeaway: HTTPS isn’t just an added layer—it's essential for privacy and trust online! Remember, if you’re sharing sensitive info, always look for the 🔒 in the URL. #CyberSecurity #WebSecurity #HTTPvsHTTPS #DataPrivacy #Infosec

🚀Day 17 | SSL/TLS and Securing Web Traffic What is SSL/TLS? SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols designed to secure communication over a computer network. They encrypt data exchanged between a user’s browser and a website, ensuring that sensitive information like passwords and credit card details are protected. How SSL/TLS Works: •Handshake: Establishes a secure connection between the client (browser) and the server. •Encryption: Uses public and private keys to encrypt the data exchanged. •Data Integrity: Ensures that data has not been tampered with during transmission. Key Concepts: →Certificates: Websites use digital certificates issued by Certificate Authorities (CA) to prove their authenticity. →HTTPS: The “S” in HTTPS stands for SSL/TLS, which secures the connection between the browser and the web server. Why is SSL/TLS Important? •Confidentiality: Prevents eavesdropping on sensitive information. •Integrity: Ensures data isn't altered during transmission. •Authentication: Verifies the legitimacy of the website. Common Uses of SSL/TLS: →Securing Websites: HTTPS protects data transmission, especially in e-commerce and banking. →VPNs: SSL/TLS is used to secure Virtual Private Network (VPN) connections. →Email Encryption: Secures emails during transmission. In a world where cyber threats are ever-present, SSL/TLS provides the security needed to protect sensitive information while browsing or interacting online. #Cybersecurity #SSLTLS #Encryption #SecureWebTraffic #DaysOfLearning #HTTPS #WebSecurity

Understanding Public & Private Keys in Website Authentication & Encryption 🔒 Public and private keys play a critical role in ensuring secure communication and authentication on websites. Here's how they work: 🔑 Public Key: Shared openly and used to encrypt data. Example: When you visit a secure website (HTTPS), your browser gets the website's public key to encrypt sensitive data like passwords or payment details. 🔑 Private Key: Kept secret and used to decrypt data encrypted with the public key. Example: The website's server uses its private key to decrypt the data you sent, ensuring only the intended recipient can read it. 💡 Use in Testing: Authentication Testing: Ensures secure login processes using public-private key pairs for user validation. Encryption Testing: Verifies that sensitive data transmitted over the web is encrypted correctly and can only be decrypted by the intended party. Why it matters? 👉 It prevents eavesdropping, data breaches, and ensures trust in online transactions. #Cybersecurity #Encryption #WebTesting #Authentication

🔒 Ensuring Website Security: Understanding HTTPS vs. HTTP 🔒 During a recent project build, I delved into the critical importance of website security, particularly focusing on the distinction between HTTPS and HTTP protocols. Here’s a deeper insight into how these protocols operate: HTTP (Hypertext Transfer Protocol): HTTP is the foundation of data communication on the World Wide Web. When a user interacts with a website using HTTP, their browser sends requests to the web server in plain text format. This means that any data exchanged between the client (browser) and the server is unencrypted and can be intercepted by malicious actors. As a result, HTTP is not recommended for transmitting sensitive information such as login credentials, credit card details, or personal data. Without encryption, the risk of data breaches and unauthorized access significantly increases. HTTPS (Hypertext Transfer Protocol Secure): HTTPS is an extension of HTTP that adds a layer of security through encryption. It utilizes SSL/TLS protocols to encrypt data during transmission, ensuring confidentiality and integrity. When a user accesses a website via HTTPS, their browser and the web server establish a secure connection by exchanging SSL/TLS certificates. These certificates verify the identity of the website and facilitate the encryption of data exchanged between the client and server. This encryption process protects sensitive information from being intercepted or tampered with by cybercriminals. Here's a simplified breakdown of how HTTPS works: Encryption: HTTPS employs encryption algorithms to scramble data before sending it over the network. Authentication: SSL/TLS certificates validate the identity of the website, assuring visitors that they are connecting to the intended server and not a malicious entity. Data Integrity: HTTPS ensures that data remains intact and unaltered during transmission, preventing unauthorized modifications. Trustworthiness: The presence of HTTPS and valid SSL/TLS certificates instills trust and credibility in visitors, encouraging secure interactions and transactions. Adopting HTTPS is not just about compliance; it's a proactive measure to protect user privacy, prevent data breaches, and build trust with your audience. It's a fundamental step towards safeguarding digital assets and maintaining a secure online presence in today's cybersecurity landscape. Stay secure, stay trusted! 💻🔐 #WebsiteSecurity #HTTPS #CyberSecurity #DigitalTrust

Imagine you're visiting a website, and your browser warns, "Not Secure" — that's because the site doesn’t have SSL (Secure Sockets Layer) to encrypt data between you and the server. SSL/TLS encryption is critical for keeping our online interactions safe! 🔐 Understanding SSL/TLS Encryption in a Nutshell! 🔐 As I've recently explored the details of SSL/TLS encryption, here's a quick breakdown of how it keeps our online interactions secure! 💡 🔑 Symmetric vs. Asymmetric Encryption Symmetric Encryption: One key is used for both encryption and decryption. Asymmetric Encryption: Uses a public key for encryption and a private key for decryption. 🌐 How SSL/TLS Secures Connections 1. Server Sends Public Key & Certificate: - The server first sends its public key along with a certificate from a trusted Certificate Authority (CA). 2. Client Verifies the Server: - The client checks the certificate against trusted CAs. If an attacker tries to use a fake certificate, the client detects it and warns the user of an untrusted connection. 3. Client Creates a Session Key: - Once verified, the client creates a session key (a symmetric key) for secure data transfer, encrypts it with the server’s public key, and sends it over. 4. Server Decrypts Session Key: - The server decrypts the session key using its private key. 5. Secure Data Exchange: - Both parties now use the same session key to encrypt and decrypt data, ensuring a secure exchange! 🔒 📝 How Certificates are Made - Digital Signatures: Created by the CA’s private key (e.g., Let’s Encrypt’s private key). - Verification: The server's public key in the certificate enables secure communication, while the CA’s public key verifies the certificate authenticity. SSL/TLS is the backbone of safe online transactions, ensuring we can browse, shop, and communicate with peace of mind! 🌍🔐 https://lnkd.in/dFj5XG2T #Cybersecurity #Encryption #SSL #TLSEncryption Piyush Garg
