詳解C#App.config和Web.config加密
打開cmd,進入vs安裝目錄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就先改為Web.config才可以進行加密
aspnet_regiis -pef "節(jié)點" "項目路徑"
例如:
需要加密的App.config數(shù)據(jù)庫連接字符串為
<connectionStrings> <add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456" /> </connectionStrings>
加密命令為
aspnet_regiis -pef "connectionStrings" "Web.config所在目錄"
如加密失敗
解決方案:
創(chuàng)建一個可導出的rsa密鑰容器,命名為Key
aspnet_regiis -pc "Key" -exp
將Web.cofig/App.config的configuration增加屬性值xmlns,即改為
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
將數(shù)據(jù)庫連接字符串改為以下:
<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>
開始對配置文件進行加密
aspnet_regiis -pef "connectionStrings" "Web.config所在目錄" -prov "KeyProvider"
注意:vs會提示是否修改,選擇全是
解密配置文件
aspnet_regiis -pdf "connectionStrings" "Web.config所在目錄"
如果是App.config改成的Web.config,加密成功之后再改為App.config,并刪除configuration的屬性xmlns值
未加密的Web.config/App.config文件內(nèi)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>
修改為加密后的Web.config/App.config文件內(nèi)容:
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

<configProtectedData>

</providers>
</configProtectedData>
<connectionStrings>
<add name="connStr" connectionString="Data Source=.;Initial Catalog=testDB;User ID=sa;Password=123456;" providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
加密后的Web.config/App.config文件內(nèi)容:
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<startup>

導出密鑰容器
spnet_regiis -px "Key" "d:\Key.xml"
注意:加上-pri參數(shù)為導出公鑰+私鑰
導入密鑰容器
aspnet_regiis -pi "Key" "d:\Key.xml"
刪除密鑰容器
aspnet_regiis -pz "Key"
注意:刪除密鑰程序會報錯
