Day 25 of the 30-Day Mentorship for Acceleration Cybersecurity Challenge – Cryptography Unlocked: Symmetric vs. Asymmetric Encryption🔐 Would you ever leave your front door wide open and just hope no one walks in? 😏 That’s what an unprotected digital world looks like. 🫠 Encryption is what locks the door—and today, we’re breaking down how it works. 🔹 Symmetric Encryption: One Key, Two Functions Imagine having one key that both locks and unlocks your front door—simple, fast, and effective. That’s symmetric encryption: using the same key for both encrypting (locking) and decrypting (unlocking) data. 💡 Example: The Advanced Encryption Standard (AES), widely used for its speed and reliability. Every time you send an email, shop online, or check your bank account, symmetric encryption is silently working in the background to keep your data safe in real time. 🔹 Asymmetric Encryption: Two Keys, Extra Security Now, think of a mailbox where anyone can drop a letter using a public slot, but only you can retrieve it with your unique private key. That’s asymmetric encryption in action. 🔑 How does it work? Uses a pair of keys—a public key for encryption and a private key for decryption. Example: RSA (Rivest-Shamir-Adleman) encryption, which is crucial for secure communications like online banking, digital signatures, and private messaging. 🔹 Why Do We Need Both? Symmetric encryption is fast and perfect for everyday tasks. Asymmetric encryption is slower but more secure, making it ideal for sensitive data exchanges. Together, they form the backbone of digital security, protecting everything from personal emails to major online transactions. 🔹 The Bigger Picture Encryption is always working behind the scenes. As cyber threats evolve, cryptography does too—ensuring our data stays protected. What’s one cybersecurity tip you think everyone should know?

Joseph Sugarman is a legendary American copywriter. He has mentored numerous successful business owners to reframe their mindset, helping them thrive in their spheres. Here are some notable quotes from his book titled ' Ad- Week Copywriting' * 'The best copywriters in the world are those who are curious about life, read a great deal, have many hobbies, like to travel, have a variety of interests often master many skills, get bored and then look for other skills to master.' This suggests that failure, knowledge search and adventures are inevitable tool for a copywriter. * Top credentials of a copywriter are:- experience, thirst for knowledge, tremendous curiosity about life, and not being afraid to work.' * 'The goal of a copy is to cause a person to exchange his or her hard-earned money for a product or service' These quotes are not only relevant to copywriters but also to everyone climbing the success ladder. #Copywriting #Joseph Sugarman #30 days challenge

Day 24: PENETRATION TESTING —STAGES #30DaysOfCybersecurityChallenge Penetration Testing follows a structured approach that involves several stages… 🔹 The First stage is RECONNAISSANCE. This is when ethical hackers gather information about your organization including network architecture, system configurations and potential entry points. This information provides a foundation for subsequent phases. 🔸 The Second Stage is ENUMERATION. In this stage, testers actively probe the organization’s systems, identifying open ports, services, and user accounts. This stage helps them gain deeper understanding of their target environment and any potential vulnerability. 🔹 The Third stage is EXPLOITATION. In this stage, ethical hackers attempt to exploit the vulnerabilities identified during reconnaissance and enumeration. They do this by simulating a real-world attack scenario to gain unauthorized access to the systems or data, highlighting the potential consequences of these vulnerabilities. 🔸 The Fourth Stage is ESCALATION. Once inside the systems, the testers escalate their privileges to gain administrative access and move freely within your network, mimicking an attacker’s action. This stage helps identify potential weaknesses in access, control, and network segmentation. 🔹 The Fifth Stage is REPORTING AND REMEDIATION. In this stage, ethical hackers generate a comprehensive report after completing the testing. The report will detail any vulnerability discovered and their potential impact. It’ll also recommend remediation steps to tighten up your security. #DigitalSecurity #PenetrationTestingStages #CyberSecurityJourney Mentorship for Acceleration

Day 25 of #myTechJourneywithM4ACE – The Impact of Color Combinations in Design Choosing the right colors isn’t just about aesthetics—it’s about communication, emotion, and functionality. Today, I explored how different color combinations influence perception and usability in design. Here’s what I learned: 🔹 Complementary Colors – Opposite on the color wheel (like blue & orange). They create strong contrast and energy but need balance to avoid visual tension. 🔹 Analogous Colors – Next to each other on the color wheel (like blue, teal, and green). They feel natural and harmonious but can sometimes lack contrast. 🔹 Triadic Colors – Three evenly spaced colors (like red, yellow, and blue). They bring vibrancy while maintaining balance. 🔹 Monochromatic Colors – Variations of a single color. They create a clean, elegant look but require contrast to keep things visually interesting. Beyond just looking good, the right color combinations enhance readability, create brand identity, and evoke emotions. Now, I pay closer attention to how brands use colors to communicate their message effectively.

📌 A Product Manager’s Perspective: Yesterday, I spent my day at the Nigeria Agrofood & Plastprintpack Trade Show, immersing myself in a world of physical products—from machinery to processed food to packaging innovations. I came across some truly inspiring products: - Vitamin A Garri made from potatoes - Non-dairy milk extracted from plant buds - Advanced machinery automating production processes As a Product Manager, my mind immediately started analyzing: 🔹 What stages were involved in developing these products? 🔹 Was an Agile or Waterfall methodology used in food processing? 🔹 How would product strategy drive the adoption of Vitamin A Garri, especially considering its higher cost than local garri that is deeply rooted in culture? Bringing an innovative product to market is one thing—ensuring adoption is another. How would you approach getting a new, more expensive alternative into an already established market? Let’s discuss! 👇 Photo Credit: Tife Adejinmi #ProductManagement Mentorship for Acceleration #PM #Agile #Waterfall #M4Ace #Innovation #Agrofood #FoodTech #ProductStrategy #M4AceCommunity Mentorship for Acceleration LLP #ProductManager #ProductLifecycle #ProductAdoption #Market

Day 25: IMPLEMENTING SYMMETRIC AND ASYMMETRIC ENCRYPTION USING OPENSSL. #30DaysOfCybersecurityChallenge I recently tackled a task that initially gave me some hesitation, but I want to walk you through the process I followed. Working in the Kali Linux terminal can be enjoyable—until you hit an error, and suddenly, the fun evaporates. This week, I was assigned the challenge of implementing both symmetric and asymmetric encryption using OpenSSL on Kali Linux. Here’s how I did it: 🔑Symmetric Encryption (AES-256-CBC) For this part, I used AES-256 in CBC mode, a robust symmetric encryption method. Here’s the breakdown: 🔹Step 1: Created a plaintext file with “touch Plaintext.txt” and added some text ("Hello World"). 🔹Step 2: Encrypted the file using “openssl enc -aes-256-cbc -salt -pbkdf2 -in Plaintext.txt -out encrypted.bin -k mysecurekey”. The “-salt” and “-pbkdf2” options enhance security by adding randomness and key derivation. 🔹Step 3: Decrypted it with “openssl enc -aes-256-cbc -d -pbkdf2 -in encrypted.bin -out decrypted.txt -k mysecurekey”. 🔹Step 4: Checked the result using “cat decrypted.txt”, which displayed "Hello World"—success! 🔑Asymmetric Encryption (RSA) Next, I moved on to RSA, an asymmetric encryption technique using public and private keys. Here’s how it went: 🔸Step 1: Generated an RSA key pair: - Private key: “openssl genrsa -out privatekey.pem 2048” - Public key: “openssl rsa -in privatekey.pem -pubout -out publickey.pem” 🔸Step 2: Encrypted the plaintext file with the public key: “openssl pkeyutl -encrypt -pubin -inkey publickey.pem -in Plaintext.txt -out encrypted_rsa.bin”. (Note: I used pkeyutl instead of the deprecated rsautl, as I’m working with OpenSSL 3.0.) 🔸Step 3: Decrypted the file using the private key: “openssl pkeyutl -decrypt -inkey privatekey.pem -in encrypted_rsa.bin -out decrypted_rsa.txt”. 🔸Step 4: Verified the output with cat decrypted_rsa.txt, and there it was: "Hello World ". ❗️Quick Tip To confirm everything worked, I used “ls” to list the directory contents and ensure all files (plaintext, encrypted files, and keys) were present. This process was a great hands-on lesson in encryption. While errors in the terminal can be daunting, breaking it down step-by-step made it manageable—and even rewarding #DigitalSecurity #Encryption #Decryption #LearningJourney Mentorship for Acceleration

Day 25: 🔐 How Digital Signatures Work: A Quick Breakdown! In today’s cybersecurity landscape, ensuring the authenticity and integrity of digital messages is critical. That’s where digital signatures come in! Here’s how they work: ✅ Step 1: Hashing A message (e.g., an email, contract, or transaction) is processed using a hash function (like SHA-256), generating a unique hash value. ✅ Step 2: Signing The sender encrypts this hash using their private key, creating a digital signature. ✅ Step 3: Verification The receiver: 🔹 Decrypts the signature using the sender’s public key to retrieve the original hash. 🔹 Computes the hash of the received message. 🔹 If both hashes match, the message is authentic and unchanged. Why Does This Matter? 🔹 Prevents tampering 🔹 Ensures authenticity 🔹 Enables non-repudiation #MentorshipForAcceleration #CyberSecurity #DigitalSignature #HashFunction #MyTechJourney #30DaysChallange Mentorship for Acceleration Idowu Oguntimehin

Day 26 of 30 days with Mentorship for Acceleration Digital Signatures: The Seal of Authenticity During WWII, high-ranking generals used wax seals or signatures to authenticate orders. If the seal was intact and the signature matched, the order was trusted. In the digital world, we achieve this through cryptographic digital signatures. How Digital Signatures Work: A digital signature ensures both integrity (the data has not been altered) and authenticity (the sender is verified). It operates using a combination of hashing functions and public-key cryptography (asymmetric encryption). i. The Sender Signs the Document: The document is hashed using an algorithm like SHA-256. The sender encrypts the hash using their private key (Digital Signature). ii. The Receiver Verifies the Signature: The receiver decrypts the signature using the sender’s public key. The receiver hashes the received document independently. If both hashes match, the document is verified. Why Digital Signatures Matter: Prevents Forgery: Only the private key holder can sign the message. Ensures Data Integrity: Any tampering invalidates the signature. Authentication: Confirms the sender’s identity beyond doubt. Real-World Applications of Digital Signatures: Email Security (PGP - Pretty Good Privacy) Secure Software Distribution (Code Signing) Blockchain Transactions Legal Digital Documents (e.g., Adobe Sign, DocuSign) #DigitalSignatures #CyberSecurity #PublicKeyCryptography #DataAuthentication #InfoSec #Encryption #CyberDefense #CyberThreats #Blockchain #CyberAwareness #30days
