Course Headline: Understand Public Key Infrastructure (PKI), OpenSSL, CSR, Certificates, Public Key Cryptosystems (RSA and ECC) in Java 🚀

Course Description:

Welcome to our comprehensive course on Public Key Infrastructure (PKI) with a focus on OpenSSL, where we will dive deep into the world of cryptography, certificates, and certificate signing requests (CSRs). This course is designed for anyone looking to master the concepts and practical applications of public key cryptosystems like RSA and Elliptic Curve Cryptography (ECC) in Java.

🔑 What You Will Learn:

• Cryptography Fundamentals: Explore the core principles of cryptography, understanding its significance in securing digital communications.

• Public and Private Keys with OpenSSL: Get hands-on experience generating RSA keys, performing encryption with RSA, and exploring the generation and implementation of ECC keys.

• Certificates: Distinguish between root certificates (self-signed certificates) and intermediate certificates, while also learning about certificate parameters and configuration files.

• Certificate Signing Request (CSR): Discover what CSRs are, how they are used to sign intermediate certificates, and the process of verifying the chain of trust.

• Transport Layer Security (TLS): Unravel the mysteries behind TLS and its role in secure network communication, including an introduction to certificate revocation lists (CRL).

• RSA Algorithm: Gain an in-depth understanding of the RSA algorithm's theory, the challenges of factorization, and the current state of its security.

• Elliptic Curve Cryptography (ECC): Delve into ECC theory, the double and add algorithm, point addition algorithm, digital signatures with elliptic curves, and the unique application of ECC in Bitcoin.
