02 通用加解密函数(crypto)

作者：沈园园　|　最后修改：2026-04-27

一、加解密概述

加解密算法是保证数据安全的基础技术，无论是在数据传输、存储，还是用户身份验证中，都起着至关重要的作用.随着互联网的发展和信息安全威胁的增加，了解并掌握常用的加解密算法已经成为开发者和安全从业者的必修课。

常见的 15 种加密解密算法分别是：散列哈希[MD5、SHA1、CRC32]，对称[DES，3DES（TDEA、Triple DES），AES、，Blowfish，RC4、RC5，IDEA]，Base64、Rabbit、Escape。

【三种分类】

1、对称加密：对称加密是指加密和解密使用同一个密钥的加密方法.由于加密和解密过程中的密钥相同，因此需要在通信双方之间安全地共享密钥.对称加密的速度较快，适合用于大量数据的加密

2、非对称加密:非对称加密算法采用一对密钥：公钥和私钥.公钥用于加密，私钥用于解密.由于加密和解密使用不同的密钥，非对称加密算法解决了密钥分发的问题，是当前加密系统中安全性最高的加密技术之一。

3、Hash 算法，这是一种不可逆的算法，它常用于验证数据的完整性。

二、演示功能概述

演示有关加解密的各种 API 的功能包含MD5，SHA，哈希(MD5，SHA)，AES/DEC/3DES，CRC，checksum校验和。

三、准备硬件环境

1、Air1601开发板一块

2、TYPE-C USB数据线一根

3、Air1601开发板和数据线的硬件接线方式为

  • Air1601开发板通过TYPE-C USB口连接TYPE-C USB 数据线，数据线的另外一端连接电脑的USB口；
  • 在 Air1601 开发板上丝印标注 USB1，为芯片烧录下载接口；
  • 若遇到因电脑 USB 端口供电不足导致的烧录失败，也可改用外部稳压电源通过开发板上的 VIN 引脚进行供电；

四、准备软件环境

4.1 软件环境

在开始实践本示例之前，先筹备一下软件环境：

1.Luatools 工具；

2.内核固件文件（底层 core 固件文件）：

本demo开发测试时使用的固件为LuatOS-SoC_V1012_Air1601_101.soc，本demo对固件版本没有什么特殊要求，所以你如果要测试本demo时，可以直接使用最新版本的内核固件；如果发现最新版本的内核固件测试有问题，可以使用我们开发本demo时使用的内核固件版本来对比测试。

3、脚本文件：https://gitee.com/openLuat/LuatOS/tree/master/module/Air1601_Air1602/demo/crypto

4、lib脚本文件：使用Luatools烧录时，勾选 添加默认lib 选项，使用默认lib脚本文件

准备好软件环境之后，接下来查看如何烧录项目文件到 Air1601 开发板中，将本篇文章中演示使用的项目文件烧录到Air1601开发板 中。
