The JEP introduces new classes and methods to handle keys and certificates stored in so-called PEM files. It was possible to load / store files in this format before this JEP, but the handling was far from easy. This JEP simplifies the handling of and allows programmers to easily work with the widely used PEM file format in their applications.</p>https://javapro-en.svenruppert.com/security-in-the-age-of-java-25-new-language-tools-for-safer-code/Tue, 30 Dec 2025 07:00:03 +0000https://javapro-en.svenruppert.com/security-in-the-age-of-java-25-new-language-tools-for-safer-code/<p>Security is more than just encryption - it&rsquo;s also about how you write code. There are several Java security features that can help prevent logic bugs, misuse of types, and unexpected state mutations. Learn how sealed classes, pattern matching, and records can reinforce domain modeling, reduce null checks, and prevent injection-prone scenarios.</p> <h2 id="introduction-why-java-security-features-matters-more-than-ever">Introduction: Why Java security features Matters More Than Ever</h2> <p>Application security has never been a static field. Over the past two decades, the Java platform has evolved not just as a runtime for enterprise applications but as a trusted foundation for industries ranging from finance and healthcare to government systems. Security breaches, once attributed primarily to poor encryption or missing authentication, now more often stem from subtler flaws: unchecked input, leaky abstractions, and poorly modeled domain logic.</p>
