What is Cryptography and Why is it Important in Cybersecurity?
Cryptography is the practice of securing communication and data by converting it into an unreadable format using mathematical algorithms. It ensures confidentiality, integrity, authentication, and non-repudiation in digital communications. Cryptography is crucial in cybersecurity because it protects sensitive information from unauthorized access, cyber threats, and data breaches.
Importance of Cryptography in Cybersecurity:
- Data Protection – Encrypts sensitive information like passwords, credit card details, and personal data.
- Secure Communication – Used in emails, messaging apps, and online transactions to prevent eavesdropping.
- Authentication & Identity Verification – Ensures only authorized users access data (e.g., digital signatures, two-factor authentication).
- Data Integrity – Ensures data is not altered or tampered with (e.g., hashing algorithms like SHA-256).
- Prevention of Cyber Threats – Defends against cyber attacks like MITM (Man-in-the-Middle), ransomware, and phishing.
