Summary
This chapter was different from the previous ones. In the previous chapters, we covered one big topic per chapter. In this chapter, however, we covered several small topics and wrote more example programs.
In this chapter, we learned about how to verify the peer certificate during a TLS handshake. We also learned about the CRL and OCSP methods. Then, we learned about TLS client certificates and PKCS #12 containers. After that, we learned how to request and verify a TLS client certificate on the server side and how to load and use client certificates on the client side. We finished this chapter by connecting our TLS server and TLS client programs, both of which support TLS client certificates, to each other.
The knowledge you’ve gained from this chapter will help you perform advanced client and server certificate processing on TLS connections in your TLS-enabled programs.
In the next chapter, we will learn about more advanced and special uses of TLS.
