This course begins by introducing fundamental encryption principles, such as symmetric and asymmetric encryption. You’ll explore key exchange algorithms and transport encryption to lay a solid foundation for digital security. From there, the course delves into the world of digital certificates, including their role in web server security and certificate authorities (CAs). Students will learn how SSL/TLS protocols are used to secure communications across the web, tracing the evolution from SSL to the more secure TLS. As the course progresses, the focus shifts to digital signatures and their crucial role in ensuring data integrity and non-repudiation. You’ll learn the cryptographic principles behind creating and verifying digital signatures, as well as the algorithms and standards commonly used in digital signature creation. Practical skills are developed through hands-on labs where you’ll work with OpenSSL and Certbot to set up web servers with Let’s Encrypt certificates. The course concludes with advanced concepts like tokenization, data masking, and blockchain. These are explored to enhance your understanding of data security and privacy. By the end of the course, you will be well-equipped to implement secure PKI solutions and navigate the complexities of digital identity management
