news2024/11/16 18:08:17

简介

libsodium主要是易用，可移植的加解密库。

下载安装

直接在OpenHarmony-SIG仓中搜索libsodium并下载。

使用说明

以OpenHarmony 3.1Beta的rk3568版本为例

库代码存放路径：./third_party/libsodium
修改添加依赖的编译脚本，路径：/developtools/bytrace_standard/ohos.build

  {
     "subsystem": "developtools",
     "parts": {
       "bytrace_standard": {
         "module_list": [
           "//developtools/bytrace_standard/interfaces/innerkits/native:bytrace_core",
           "//developtools/bytrace_standard/bin:bytrace_target",
           "//developtools/bytrace_standard/bin:bytrace.cfg",
           "//developtools/bytrace_standard/interfaces/kits/js/napi:bytrace",
           "//third_party/libsodium:libsodium",
           "//third_party/libsodium:libsodium_test"
         ],
         "inner_kits": [
           {
             "type": "so",
             "name": "//developtools/bytrace_standard/interfaces/innerkits/native:bytrace_core",
             "header": {
               "header_files": [
                 "bytrace.h"
               ],
               "header_base": "//developtools/bytrace_standard/interfaces/innerkits/native/include"
             }
           }
         ],
          "test_list": [
           "//developtools/bytrace_standard/bin/test:unittest"
         ]
       }
     }
   }

用命令 ./build.sh --product-name rk3568 --ccache 编译
生成库文件路径：out/rk3568/graphic/graphic_standard，该路径会生成库文件

接口说明

初始化库
