Summary

In this chapter, we looked at several small, but significant changes to the JDK that involve security. The featured security enhancements that are part of the Java 9 platform provide developers with the distinct ability to write and maintain applications that implement security. Specifically, we covered DTLS, keystores, improving security application performance, the TLS application-layer protocol negotiation extension, leveraging CPU instructions for GHASH and RSA, OCSP stapling for TLS, and DRBG-based SecureRandom implementations.

In the next chapter we will explore the new command-line flags used in Java 9 as well as changes to various command-line tools. Our coverage will include managing the Java JVM run-time and compiler using the new command-line options and flags.
