[C#] Decrypt RDP passwords

[alien]

As some of you requested, I've added a class to decrypt passwords found in *.rdp files.

To work with this class add the DLL to references, include the namespace in you're class "using DataProtection;" and use the two functions provided by DataProtectionWrapper: Encrypt(string) and Decrypt(string)

The repository can be found here:

hg clone https://bitbucket.org/rokill3r/rdppassworddecrypter

DLL can be found here: DataProtection.dll

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using DataProtection;


namespace RdpPasswordDecrypter
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                string password = "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";
                Console.WriteLine("Decrypting ...");
                Console.WriteLine("Password: " + DataProtectionWrapper.Decrypt(password));
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
}

Log output:

Olá é o programa funciona bem para a figura e descrito com DPAPI, entretanto falha ao tentar decifrar a senha armazenada nos perfis das redes Windows wifi.

Existe alguma maneira de decifrar a senha armazenada em redes xml perfis do Windows com C#
