本文内容本文主要第1节 PyQt5环境搭建和配置。主要内容包括：
[!TIP]
（1）工具版本的选择，包括PyQt版本和Python软件版本。
（2）Python、PyQt5以及Qt Designer工具的安装。QtDesigner是PyQt的可视化GUI设置工具。
（3）PyCharm上配置Qt Designer和PyUIC工具。
选择PyQt原因（1）PyQt可以通过拖拽实现界面开发，而不是只能代码实现。这样界面实现效率就高多了。
（2）控件丰富。支持跨平台。
（3）方便打包发布。可以利用Pyinstaller打包成二进制文件。在未安装Python软件电脑上运行。
选择Python3和PyQt5原因PyQt官网提供了PyQt4和PyQt5两种主流版本。PyQt5不兼容PyQt4。建议选择PyQt5原因：
（1）官方对PyQt4不再有重大更新和维护。
（2）PyQt ...</div></div></div><div class="recent-post-item"><div class="recent-post-info no-cover"><a class="article-title" href="/2023/04/07/optee/optee/" title="tee站点收藏">tee站点收藏</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2023-04-07T03:12:20.000Z" title="发表于 2023-04-07 11:12:20">2023-04-07</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2024-11-22T04:33:43.309Z" title="更新于 2024-11-22 12:33:43">2024-11-22</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/optee/">optee</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/optee/">optee</a></span></div><div class="content">TEE安全系统SMC深入理解Linux设备驱动基础02：Linux内核模块用户态和内核态的区别SM2算法第三篇：实现SM2秘钥交换协议的算法流程

一、什么是shell？shell是一个用 C 语言编写的程序，它是用户使用 Linux 的桥梁。Shell 既是一种命令语言，又是一种程序设计语言。
Shell 是指一种应用程序，这个应用程序提供了一个界面，用户通过这个界面访问操作系统内核的服务。
为什么要学习和使用shell？Shell属于内置的脚本，程序开发的效率非常高，依赖于功能强大的命令可以迅速地完成开发任务（批处理）语法简单，代码写起来比较轻松，简单易学
二、shell的分类cat /etc/shells
在linux中有很多类型的shell，不同的shell具备不同的功能，shell还决定了脚本中函数的语法，Linux中默认的shell是/ b a s h / b a s h （ 重 点 ），流行的shell有ash、bash、ksh、csh、zsh等，不同的shell都有自己的特点以及用途。
编写规范:
#!/bin/bash [指定告知系统当前这个脚本要使用的shell解释器]
Shell相关指令
文件命名规范：

最简单的证书包含一个公开密钥、名称以及证书授权中心的数字签名。数字证书还有一个重要的特征就是只在特定的时间段内有效。数字证书是一种权威性的电子文档，可以由权威公正的第三方机构，即CA（例如中国各地方的CA公司）中心签发的证书，也可以由企业级CA系统进行签发。
一般证书分有三类，根证书、服务器证书和客户端证书。根证书，是生成服务器证书和客户端证书的基础，是信任的源头，也可以叫自签发证书，即CA证书。服务器证书，由根证书签发，配置在服务器上的证书。客户端证书，由根证书签发，配置在服务器上，并发送给客户，让客户安装在浏览器里的证书。
对称加密：例如平时给文件加密，加密和解密用的同一密码，即对称加密。
非对称加密：加密时用一个密码，而解锁时需要用另一个密码，即非对称加密。目前很流行的非对称加密算法是RSA算法，它是基于一个十分简单的数论事实：将两个大素数相乘十分容易，但是想要对其乘积进行因式分解却极其困难，因此可以将乘积公开作为加密密钥。
公钥：公钥是公开的，用来传输对方的随机密钥，只有通过私 ...</div></div></div><div class="recent-post-item"><div class="recent-post-info no-cover"><a class="article-title" href="/2023/01/09/c++/C++%E5%9F%BA%E7%A1%80%E5%85%A5%E9%97%A8/" title="C++基础入门">C++基础入门</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2023-01-09T10:12:20.000Z" title="发表于 2023-01-09 18:12:20">2023-01-09</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2024-11-22T04:34:48.551Z" title="更新于 2024-11-22 12:34:48">2024-11-22</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/C/">C++</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/C-%E5%AD%A6%E4%B9%A0/">C++ 学习</a></span></div><div class="content">C++基础入门1 C++初识1.1 第一个C++程序编写一个C++程序总共分为4个步骤
创建项目
创建文件
编写代码
运行程序
1.1.1 创建项目 Visual Studio是我们用来编写C++程序的主要工具，我们先将它打开
1.1.2 创建文件右键源文件，选择添加->新建项
给C++文件起个名称，然后点击添加即可。
1.1.3 编写代码1234567891011#include<iostream>using namespace std;int main() { cout << "Hello world" << endl; system("pause"); return 0;}
1.1.4 运行程序
1.2 注释作用：在代码中加一些说明和解释，方便自己或其他程序员程序员阅读代码
两种格式
单行注释：// 描述信息
通常放在一行代码的上方，或者一条语句的末尾，==对该行代码说明==
多行注释： /* 描述信息 */

1 内存分区模型C++程序在执行时，将内存大方向划分为4个区域
代码区：存放函数体的二进制代码，由操作系统进行管理的
全局区：存放全局变量和静态变量以及常量
栈区：由编译器自动分配释放, 存放函数的参数值,局部变量等
堆区：由程序员分配和释放,若程序员不释放,程序结束时由操作系统回收
内存四区意义：
不同区域存放的数据，赋予不同的生命周期, 给我们更大的灵活编程
1.1 程序运行前 在程序编译后，生成了exe可执行程序，未执行该程序前分为两个区域
代码区：
存放 CPU 执行的机器指令
代码区是共享的，共享的目的是对于频繁被执行的程序，只需要在内存中有一份代码即可
代码区是只读的，使其只读的原因是防止程序意外地修改了它的指令
全局区：
全局变量和静态变量存放在此.
全局区还包含了常量区, 字符串常量和其他常量也存放在此.
==该区域的数据在程序结束后由操作系统释放=&#x ...</div></div></div><div class="recent-post-item"><div class="recent-post-info no-cover"><a class="article-title" href="/2023/01/07/linux/linux_code/" title="code">code</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2023-01-07T12:12:20.000Z" title="发表于 2023-01-07 20:12:20">2023-01-07</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2023-07-05T02:31:54.439Z" title="更新于 2023-07-05 10:31:54">2023-07-05</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/linux/">linux</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/C/">C</a></span></div><div class="content">
