Learning about Java security and encryption is very important, especially when developing applications that involve sensitive data. Here are some suggestions for learning Java security and encryption:
Basic knowledge:
First, understand the basic concepts of computer network security, including encryption, decryption, hash algorithms, digital signatures, etc. Learn about types of security attacks and common security threats.
Java security APIs:
Learn about security APIs provided by Java, such as Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE). These APIs provide the classes and methods needed to perform encryption and decryption operations.
SSL/TLS：
Understand the SSL (Secure Socket Layer) and TLS (Transport Layer Security) protocols in Java, which are used to ensure the security of data in network communication.
Digital certificate:
Learn the concepts and uses of digital certificates, and learn how to use digital certificates for authentication and data signing in Java.
Cryptographic algorithm:
Learn common cryptographic algorithms, such as symmetric encryption algorithms (such as AES, DES), asymmetric encryption algorithms (such as RSA, DSA), hash algorithms (such as SHA-256), etc.
Security Vulnerabilities and Defenses:
Learn about common security vulnerabilities such as cross-site scripting (XSS), SQL injection, cross-site request forgery (CSRF), and more, and learn how to defend against them through coding practices and security measures.
Online resources:
Take advantage of online tutorials, documentation, and learning resources such as Oracle's official documentation, Java security-related books, and online courses.
Learning Java security and encryption takes time and patience, but mastering this knowledge will help keep your applications and data safe.
