::raises hand:: I do this on my site -- you can also encrypt sql connections!  (REALLY GOOD IDEA)

 create a button and make this its event

protected void Button1_Click(object sender, EventArgs e)

{

ProtectSection("connectionStrings", "DataProtectionConfigurationProvider");

}

to unencrypt...

protected void Button2_Click(object sender, EventArgs e)

{

UnprotectSection("connectionStrings");

}

functions are the same as given on the link above (for fun, I pasted them below), and don't forget to add System.Web.Configuration

private void ProtectSection(string sectionName, string provider)

{

Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);

ConfigurationSection section = config.GetSection(sectionName);

if (section != null && !section.SectionInformation.IsProtected)

{

section.SectionInformation.ProtectSection(provider);

config.Save();

}

}

private void UnprotectSection(string sectionName)

{

Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);

ConfigurationSection section = config.GetSection(sectionName);

if (section != null && section.SectionInformation.IsProtected)

{

section.SectionInformation.UnprotectSection();

config.Save();

}

}
