JDK 28: Named Group Information Captured in the TLSHandshake JFR Event

Starting with JDK 28, the jdk.TLSHandshake JFR event captures the named group information negotiated during TLS key exchange, such as X25519MLKEM768. This event is disabled by default and must be enabled via a JFR configuration file, jfr configure, or when launching the application. The new field lets developers inspect exactly which key-exchange group was used to establish a TLS connection's shared secret using the jfr print command.

Why read it: Bài viết cung cấp thông tin về tính năng mới trong JDK 28 giúp theo dõi và phân tích các nhóm key-exchange được sử dụng trong kết nối TLS, hỗ trợ hiệu quả việc bảo mật và gỡ lỗi hệ thống.
