Cybersecurity & Cryptography : Secure Data & Networks | Udemy

This course will teach you cryptography from scratch in a simple and practical way. You will learn how encryption secures the internet, protects data, and prevents cyber attacks.

We start with encryption, hashing, and digital certificates before moving to advanced topics like SSL/TLS, secure key exchange, and real-world cybersecurity applications. You will understand how websites like WhatsApp, Gmail, and Zoom use encryption to protect data from hackers and cyber threats.

What You Will Learn:

• The difference between symmetric and asymmetric encryption (AES, RSA, and more)
• How SSL/TLS encryption secures websites and online transactions
• Hashing techniques (SHA, HMAC) for data integrity and authentication
• How to use OpenSSL and Wireshark to analyze encrypted connections
• Secure key exchange methods like Diffie-Hellman and Public Key Infrastructure (PKI)
• Practical demonstrations on encryption, decryption, and certificate management

Who Is This Course For?

• Beginners in cybersecurity and ethical hacking
• IT professionals, developers, and network engineers
• Anyone interested in secure digital communication and data protection

No prior knowledge is required. By the end, you will have a strong foundation in cryptography and be able to apply encryption in real-world security scenarios confidently.
