+# libsrtp三方库说明
+## 功能简介
+libSRTP提供了保护RTP和RTCP的功能。RTP数据包可以进行加密和身份验证（使用srtp_protect（）函数），将其转换为srtp数据包。
+## 使用约束
+- IDE版本：DevEco Studio 3.1 Beta2
+- SDK版本：ohos_sdk_public 3.2.11.9 (API Version 9 Release)
+- 三方库版本：v2.5.0 
+- 当前适配的功能：支持加密的rtp数据包传输
+- [2001-2017 Cisco Systems, Inc](https://github.com/cisco/libsrtp/blob/main/LICENSE)

+# libsrtp集成到应用hap
+本库是在RK3568开发板上基于OpenHarmony3.2 Release版本的镜像验证的，如果是从未使用过RK3568，可以先查看[润和RK3568开发板标准系统快速上手](https://gitee.com/openharmony-sig/knowledge_demo_temp/tree/master/docs/rk3568_helloworld)。
+## 开发环境
+- ubuntu20.04
+- [OpenHarmony3.2Release镜像](https://gitee.com/link?target=https%3A%2F%2Frepo.huaweicloud.com%2Fopenharmony%2Fos%2F3.2-Release%2Fdayu200_standard_arm32.tar.gz)

+- [准备三方库构建环境](../../../tools/README.md#编译环境准备)
+- [准备三方库测试环境](../../../tools/README.md#ci环境准备)
+## 编译三方库
+- 下载本仓库
+  ```
+  git clone https://gitee.com/openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+- 三方库目录结构
+  ```
+  tpc_c_cplusplus/thirdparty/libsrtp    #三方库libsrtp的目录结构如下
+  ├── docs                              #三方库相关文档的文件夹
+  ├── HPKBUILD                          #构建脚本
+  ├── SHA512SUM                         #三方库校验文件
+  ├── README.OpenSource                 #说明三方库源码的下载地址，版本，license等信息
+  ├── README_zh.md   
+  ├── libsrtp_oh_pkg.patch              #三方库libsrtp的patch文件 
+  ```
+  
+- 将libsrtp拷贝至tools/main目录下,并且将依赖的openssl和libpcap也拷贝至tools/main目录下
+  ```
+  cd tpc_c_cplusplus
+  cp thirdparty/libsrtp tools/main -rf
+  cp thirdparty/openssl tools/main -rf
+  cp thirdparty/libpcap tools/main -rf
+  ```
+- 在tools目录下编译三方库
+  编译环境的搭建参考[准备三方库构建环境](../../../tools/README.md#编译环境准备)
+  ```
+  cd tools
+  ./build.sh libsrtp openssl  libpcap
+  ```
+- 三方库头文件及生成的库
+  在tools目录下会生成usr目录，该目录下存在已编译完成的32位和64位三方库
+  
+  ```
+  libsrtp/arm64-v8a   libsrtp/armeabi-v7a  libpcap/arm64-v8a libpcap/armeabi-v7a openssl/arm64-v8a openssl/armeabi-v7a   
+  ```
+  
+- [测试三方库](#测试三方库)
+
+## 应用中使用三方库
+
+- 在IDE的cpp目录下新增thirdparty目录，将编译生成的库拷贝到该目录下，如下图所示
+&nbsp;![thirdparty_install_dir](pic/libsrtp_install_dir.png)
+- 在最外层（cpp目录下）CMakeLists.txt中添加如下语句
+  ```
+  #将三方库加入工程中
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libsrtp/${OHOS_ARCH}/lib/libsrtp2.a)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libpcap/${OHOS_ARCH}/lib/libpcap.a)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/openssl/${OHOS_ARCH}/lib/libssl.a)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/openssl/${OHOS_ARCH}/lib/libcrypto.a)
+#将三方库的头文件加入工程中
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libsrtp/${OHOS_ARCH}/include)
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libpcap/${OHOS_ARCH}/include)
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/openssl/${OHOS_ARCH}/include)
+  ```
+  ![libsrtp_usage](pic/libsrtp_usage.png)
+## 测试三方库
+三方库的测试使用原库自带的测试用例来做测试，[准备三方库测试环境](../../../tools/README.md#ci环境准备)
+
+进入到构建目录执行ctest运行测试用例（arm64-v8a-build为构建64位的目录，armeabi-v7a-build为构建32位的目录）
