Technical requirements

This chapter will contain commands that you can run on a command line along with C source code that you can also build and run. For the command-line commands, you will need the openssl command-line tool with OpenSSL dynamic libraries. To build the C code, you will need OpenSSL dynamic or static libraries, library headers, a C compiler, and a linker.

We will implement an example program in this chapter, in order to practice what we are learning. The full source code of that program can be found here: https://github.com/PacktPublishing/Demystifying-Cryptography-with-OpenSSL-3/tree/main/Chapter04.
