bytecode-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.

"That" virtualization-based (VM) JavaScript (JS) Obfuscator

JVMTI agent + JNI library for AES-based Java class bytecode encryption and runtime decryption. Works with mjar-java for build-time encryption and agent-based loading. 基于 JVMTI + JNI 的 Java class 字节码 AES 加密与运行时解密库，配合 mjar-java 实现构建时加密和 Agent 按需解密。
