+# ViperOpenSSLProject
+
+基于 [ViperTemplateProject](../ViperTemplateProject) 模板创建的 **OpenSSL 3.x FFI 测试工程**，
+用来验证 `includes/openssl` FFI 层（摘要/哈希、EVP、证书 PKI、SSL/TLS）的链接与调用。
+
+## 说明
+
+- FFI 层源码在 `../includes/openssl/`（`import openssl` 使用）。
+- 当前 App/main.vp 为「版本 + SHA256/MD5 摘要」演示。
+- 尚未决定链接目标（msys2 预装 3.6.2 动态库 或 openssl_358_C 自编译静态库），
+  本工程 `project.vpj` **暂未配置 openssl 链接参数**，需要时再补。
+
+## 目录结构
+
+```
+ViperOpenSSLProject/
+├── .gitignore
+├── LICENSE
+├── README.md
+├── project.vpj          # 编译/链接配置（openssl 链接目标待定）
+└── App/
+    └── main.vp          # 版本 + 摘要演示
+```
+
+## 链接参考（后续选择其一填入 project.vpj）
+
+### 方式 A：msys2 预装 3.6.2 动态库（推荐先试）
+在 `project.vpj` 的 `linker.flags` 中加入：
+
+```
+"-L D:/msys64/mingw64/lib",
+"-lcrypto",
+"-lssl"
+```
+
+运行 app.exe 前需把 `D:/msys64/mingw64/bin` 加入 PATH（`libcrypto-3-x64.dll` / `libssl-3-x64.dll`）。
+
+### 方式 B：openssl_358_C 源码自编译静态库
+先用 perl Configure + mingw 编译 `../includes/openssl/openssl_358_C`，再把
+生成的 `libcrypto.a` / `libssl.a` 填入 `linker.static_libs`。
+
+## 编译运行
+
+```powershell
+cd D:\Users\TermiNexus\Desktop\TransPyC\ViperOpenSSLProject
+python ..\Projectrans.py --project .\project.vpj --clean-cache=false
+.\output\app.exe   # 注意：openssl 链接参数配好前编译/链接会失败
+```
