Public Key Infrastructure (PKI) with OpenSSL (RSA and ECC)

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.

Chapter 1 – Cryptography Fundamentals

• what is the aim of cryptography?
• private key and public key cryptosystems

Chapter 2 – Public and Private Keys in OpenSSL

• generating RSA keys
• encryption example with RSA
• generating ECC keys

Chapter 3 – Certificates

• root certificates (self-signed certificates) and intermediate certificates
• certificate parameters and configuration files

Chapter 4 – Certificate Signing Request (CSR)

• what are certificate signing requests?
• signing intermediate certificates
• verifying the chain of trust

Chapter 5 – Transport Layer Protocol (TLS)

• what is the transport layer protocol?
• how network communication works
• certificate revocation list (CRL)

Chapter 6 – RSA Algorithm

• RSA algorithm theory
• the problem of factorization
• is it possible to crack RSA algorithm?

Chapter 7 – Elliptic Curve Cryptography (ECC)

• elliptic curve cryptography theory
• double and add algorithm
• point addition algorithm
• digital signatures with elliptic curves
• why does Bitcoin use elliptic curve cryptography?
• is it possible to crack elliptic curves?
