打开cmd，进入VS安装目录C:\Windows\Microsoft.NET\Framework64\v4.0.30319，如果是Web.config则直接加密，是App.config则先改为Web.config再进行加密。命令如下：aspnet_regiis -。
打开cmd，进入vs安装目录C:\Windows\Microsoft.NET\Framework64\v4.0.30319
cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319
如果是Web.config就直接加密，是App.config就先改为Web.config才可以进行加密
aspnet_regiis -pef "节点" "项目路径"
例如：
需要加密的App.config数据库连接字符串为
<connectionStrings> <add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456" /> </connectionStrings>
加密命令为
aspnet_regiis -pef "connectionStrings" "Web.config所在目录"
如加密失败
解决方案：
创建一个可导出的rsa密钥容器，命名为Key
aspnet_regiis -pc "Key" -exp
将Web.cofig/App.config的configuration增加属性值xmlns，即改为
<configuration xmlns="schemas.microsoft.com/.NetConfiguration/v2.0">
将数据库连接字符串改为以下：
<configProtectedData> <providers> <clear /> <add name="KeyProvider" type="System.Configuration.RsaProtectedConfigurationProvider, System.Configuration, Version=2.0.0.0,Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" keyContainerName="Key" useMachineContainer="true"/> </providers> </configProtectedData> <connectionStrings> <add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" /> </connectionStrings>
开始对配置文件进行加密
aspnet_regiis -pef "connectionStrings" "Web.config所在目录" -prov "KeyProvider"
注意：vs会提示是否修改，选择全是
解密配置文件
aspnet_regiis -pdf "connectionStrings" "Web.config所在目录"
如果是App.config改成的Web.config，加密成功之后再改为App.config，并删除configuration的属性xmlns值
未加密的Web.config/App.config文件内容：
<?xml version="1.0" encoding="utf-8" ?> <configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> </startup> <connectionStrings> <add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456" /> </connectionStrings> </configuration>
修改为加密后的Web.config/App.config文件内容：
<?xml version="1.0" encoding="utf-8" ?> <configuration xmlns="schemas.microsoft.com/.NetConfiguration/v2.0"> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> </startup> <configProtectedData> <providers> <clear /> <add name="KeyProvider" type="System.Configuration.RsaProtectedConfigurationProvider, System.Configuration, Version=2.0.0.0,Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" keyContainerName="Key" useMachineContainer="true"/> </providers> </configProtectedData> <connectionStrings> <add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" /> </connectionStrings> </configuration>

导出密钥容器
spnet_regiis -px "Key" "d:\Key.xml"
注意：加上-pri参数为导出公钥+私钥
导入密钥容器
aspnet_regiis -pi "Key" "d:\Key.xml"
删除密钥容器
aspnet_regiis -pz "Key"
注意：删除密钥程序会报错
