static public void SetPassAndProtectSection(string newPassword)
{

    // Get the current configuration file.
    System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);


    // Get the section.
    MyAppProtectedSection section = 
        (MyAppProtectedSection)config.GetSection(DEFAULT_SECTION_NAME);

    section.DBPassword = newPassword;

    // Protect (encrypt)the section.
    section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");

    // Save the encrypted section.
    section.SectionInformation.ForceSave = true;

    config.Save(ConfigurationSaveMode.Full);
}

这似乎工作正常,但我需要一些额外的信息为我的文档.

密钥存储在哪里？

钥匙多长时间？
