测试
测试使用pytest和oscrypto编写，并要求安装这些包：
$ pip3 install pytest oscrypto $ git clone --recurse-submodules https://github.com/Infineon/python-optiga-trust ... $ cd python-optiga-trust $ cd tests $ pytest
要只运行一些测试，请将正则表达式作为参数传递给tests。
$ pytest test_rand.py
添加对您自己的嵌入式Linux的支持
您需要为您的平台构建共享库，为此，您需要在系统中安装cmake和build-essential软件包
然后您可以执行以下操作
$ cdcd python-optiga-trust/lib/optigatrust/csrc $ mkdir build &&cd build $ cmake .. $ make<详细信息>
