ASPNET_REGIIS -pef Vs -pe

Using ASPNET_REGIIS we can encrypt the web.config using these 2 parameters:-

ASPNET_REGIIS -pef

ASPNET_REGIIS -pe

So what are the main differences between the 2 paramters?

If you run the executable without any options, the list of all options is outputted, and -pe and -pef state:

Params

-pe for one can take a wider variety of arguments than -pef. Additionally, -pef expects the web-app-physical-dir to find the Web.config to encrypt, where as -pe uses virtual paths to find the file instead.

I went and tested this with a dummy website and the default provider, and it seems it doesn't do anything different. The resulting encryption used was the same:

Using -pe

<configuration>
  <connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
      <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"

Using -pef:

<configuration>
  <connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
      <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"
          xmlns="http://www.w3.org/2001/04/xmlenc#">

      </EncryptedData>
  </connectionStrings>
   ...

Apart from usage differences, there doesn't appear to be any differences in terms of how it encrypts.
