Oracle has announced the release of Java 27, a new version of the development platform that prioritizes security and incorporates significant advancements in post-quantum cryptography. Furthermore, the update brings notable performance optimizations, such as the standard adoption of compact object headers and enhanced support for artificial intelligence applications.
The official announcement of Java 27 took place this Tuesday, September 15th. This version of the classic platform draws particular attention due to its security reinforcements, highlighting progress in the area of post-quantum cryptography.
Post-quantum cryptography represents a security methodology designed to prevent protected information from being exposed using the power of a quantum computer. Although Java already had some prior support for this functionality, Java 27 introduces support for hybrid cryptographic key exchange algorithms directly into the TLS 1.3 protocol via modification JEP 527. This feature aims to thwart attacks known as 'harvest now, decrypt later,' which involve collecting encrypted data for later decryption.
In the field of security, the new edition also improves support for PEM (Privacy Enhanced Mail) format files, which are used to store private cryptographic keys or digital certificates. Additionally, it is now possible to obscure sensitive data within the Java Flight Recorder (JFR) diagnostic and monitoring tool.
Performance improvements were implemented through specific changes. Change JEP 534 establishes compact object headers as the standard, aiming to reduce memory consumption. Meanwhile, JEP 537 optimizes the Vector API, allowing instructions to be executed on multiple data points simultaneously, which accelerates data-intensive operations, such as those used in artificial intelligence.
In summary, Java 27 consolidates a vast set of innovations formalized both in JDK Enhancement Proposals (JEP) and minor features. However, the biggest highlight lies in the advances in post-quantum cryptography. With this release, Oracle reaches an important milestone in this field, progressing towards features similar to those offered in long-term support JDK versions, helping customers protect business assets with less disruption.
Georges Saab, Senior Vice President of Oracle Java Platform, commented on the company's advancement in this sector. Users can obtain Oracle JDK 27 from the official website, with versions available for Windows, Linux, and macOS. Alternatively, OpenJDK 27, the open-source implementation of Java, can be downloaded. Java 27 follows the platform's semi-annual update cycle, arriving six months after the release of Java 26.
