VS2022中使用Cryptopp加密库

下载地址

cryptopp：

官方文档

下载cryptopp和cryptopp-pem

将pem项目中的全部内容复制到cryptopp中

Cryptopp项目库生成

打开后有四个子工程

cryptdll - 生成cryptopp.dll动态库

dlltest - 用来测试cryptopp.dll，依赖cryptdll工程

cryptlib - 生成cryptlib.lib静态库

cryptest - 用来测试cryptopp，依赖cryptlib工程

在crtptlib中Header Files => 添加 => 现有项

1 2	pem.h pem_common.h

Source Files => 添加 => 现有项

1
2
3

pem_common.cpp
pem_read.cpp
pem_write.cpp

重新在DEBUG和RELEASE生成

最终会在项目目录生成x64/Output文件夹

文件夹内容为lib库

新建文件夹crypropp和子文件夹include和lib

将cryptopp中所有.h的头文件copy到include

将Output文件夹放入lib

VS2022使用cryptopp库

新建控制台项目

替换项目为官方AES代码
