jar-encryption

Java Guard 通过 JAR 字节码与资源加密、运行时解密、Ed25519 签名校验和 Rust 原生启动器提高 Java 应用逆向与篡改门槛，无需修改业务代码。Java Guard raises the cost of reverse engineering and tampering through JAR bytecode/resource encryption, runtime decryption, Ed25519 verification, and a Rust native launcher—without application code changes.

Encrypt Java classes inside JAR/WAR with ASM bytecode transformation, to be used together with the native mjar agent for runtime decryption. Support Spring Boot fat jars and nested archives. 使用 ASM 对 JAR/WAR 中指定包下的 class 进行加密和字节码补丁，配合 mjar 原生 Agent 在运行时解密加载，支持 Spring Boot fat jar 和嵌套包。
