The Power of Data Encryption in Securing Information
Data encryption is the process of converting readable information, known as plaintext, into an unreadable and scrambled format called ciphertext. This is done using an algorithm and a key, which are essential for both encrypting and decrypting the data. The primary purpose of data encryption is to ensure the confidentiality and integrity of information, preventing unauthorized parties from accessing or understanding it. It’s a fundamental pillar of cybersecurity, used everywhere from online banking and e-commerce to secure messaging and cloud storage, providing a vital layer of protection for sensitive personal and professional data in transit and at rest.
