Password hash in RDP files

[Remko]

I agree the code is Spaghetti, I just made it quickly to test it. I will tidy it up and make it more readable.
I checked and rdp file with HEX viewer and indeed it starts with FF FE (although mstsc doesn't bother absence of it).

I already made the plaintext password a WideString but I keep ending with a hash about 350 bytes long while MSTSC always produces 1329 bytes. Also each time I save the RDP file the hash is different.
