Hi Nitesh,
Encrypt and Decrypt Connection Strings is very usefully for security point.Like when we are developing a application which secured then connection string Encrypt and Decrypt is one of steps.

Define these string at top of page before page load.

string provider = "RSAProtectedConfigurationProvider";
string section = "connectionStrings";

Encrypt connection string code below:

  public void Encrypt_connection()
    {

        Configuration confg = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
        ConfigurationSection configSect = confg.GetSection(section);
        if (configSect != null)
        {
            configSect.SectionInformation.ProtectSection(provider);
            confg.Save();
        }
    }

Decrypt connection string code below:

 public void Decrypt_connection()
    {
        Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
        ConfigurationSection configSect = config.GetSection(section);
        if (configSect.SectionInformation.IsProtected)
        {
            configSect.SectionInformation.UnprotectSection();
            config.Save();
        }
    }
