Security

J2eeFAST was originally developed primarily for banking projects, with a strong emphasis on system security. It follows Web security standards, encrypts database transmission, and stores passwords as hashed ciphertext. It provides page-level button permission controls, strict data filtering, and SQL input filtering, fundamentally preventing common Web attacks such as SQL injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF).

Source Code Control

J2eeFAST is 100% open source, with detailed comments that make the code easy to read. The code contains no backdoors and can be used with confidence. It provides a rich collection of plugins and interfaces for easy extension, comprehensive documentation, active responses to user feedback, and a technical discussion group.
