Introduction In today's digital age, protecting your sensitive information from prying eyes is more important than ever. With so much personal data being shared online, it's crucial to have measures in place to keep your information secure. This is where cryptography comes in. What is Cryptography? Cryptography is the practice of using mathematical algorithms to encrypt data, making it unintelligible to anyone who doesn't have the key to decrypt it. This means that even if your data is intercepted or stolen, it will be useless to anyone who doesn't have the key to unlock it. How Cryptography Can Protect Your Online Transactions One of the most common uses of cryptography is in online transactions, such as online banking or e-commerce. When you make a transaction online, your sensitive information, such as your credit card number or personal details, is encrypted using cryptographic algorithms.
