What you'll learn:
- Understand the basics of public key crypto-systems
- Understand the basics of public key infrastructure (PKI)
- Understand certificates (root and intermediate certificates)
- Understand certificate signing requests (CSRs)
- Understand RSA and ECC
- Understand TLS protocol
In this course you will learn about cryptography, certificates and certificate signing requests (CSRs) with OpenSSL. You will understand the most popular pubic key (asymmetric) cryptosystems on a step by step basis - such as RSA and Elliptic Curve cryptosystems. You can learn about the theory as well as the implementation for every approach.
