aspnet_setreg.exe

Various places (including
http://msdn.microsoft.com/library/de...itySection.asp) say:

You can create the encrypted credentials and store them in the registry with
the ASP.NET Set Registry console application (Aspnet_setreg.exe), which uses
CryptProtectData to accomplish the encryption. To download Aspnet_setreg.exe,
along with the Visual C++ source code and documentation, visit the Web site
www.asp.net and search for "aspnet_setreg".


I have been unable to locate the source code for this program. The best I
could find on www.asp.net was a forum thread by someone asking where the
source code is, and noone having an answer.)

So, where is the source code?! I am looking to duplicate its functionality
in my program.
