# 對 ASP.NET 應用程式中 web.config 敏感資料加解密最簡單的方式

### 加密 web.config 的連接字串 (.NET Framework 2.0)

```batch
cd c:\inetpub\wwwroot   (你的應用程式目錄)
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -pef connectionStrings . -prov DataProtectionConfigurationProvider
```

### 解密 web.config 的連接字串 (.NET Framework 2.0)

```batch
cd c:\inetpub\wwwroot   (你的應用程式目錄)
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -pdf connectionStrings .
```

### 加密/解密 web.config 連接字串 (.NET Framework 4.0+)

```powershell
C:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pef connectionStrings C:\inetpub\wwwroot -prov DataProtectionConfigurationProvider
```

```powershell
C:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pdf connectionStrings C:\inetpub\wwwroot
```

### 加密/解密 web.config 應用程式設定 (.NET Framework 4.0+)
