Encrypt, decrypt the Web. config database connection string

The "connectionStrings" path is the project directory where Web. config resides.

1, encryption Encryptwebconfig.bat

@echo off
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pef "connectionStrings" "D:\Web"
PAUSE

2, decryption Decryptwebconfig.bat

@echo off
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -pdf "connectionStrings" "D:\Web"
PAUSE

The black one is the difference between the two files.

Note: This method is encrypted and can only be used on the computer that performs the encryption, because the machine signature is required when ASP. NET automatically decrypts, so encryption is encrypted on the server,

If you want to have more than one server, you need to use the RSA key container.
