Understanding the RH/XV system

First the shift "3"

S| 0123456789
--------------
2| 8901234567
6| 4567890123
5| 5678901234
8| 2345678901

Normally we don't have a "3" first and we would simply do

0123456789 -> 3970145628
3480567291 -> 0123456789

Its exactly the same but we do the same to all not individually (otherwise "31" would be the same as "13" which it isn't!!)

3480567291 -> 0123456789
-------------------------
8901234567 -> 1758923406
4567890123 -> 7314589062
5678901234 -> 8425690173
2345678901 -> 5192367840

Now pin shift to rearrange the digits

4213 - 3241

NOTE we don't rearrange the LUT (as in previous examples) because the "2" is after the "1" - we would if 23 = 321 !!)


e.g 0042343 - 3244 PIN = 8163

Many Thanks for your quick reply.

Thanks Nix9!

I was in the same boat as 1234digital.

Took me a little while to get my head around it but I did eventually - and it worked!

Thanks again for taking the time and effort to explain.

 

[Boolian]

e.g 0042343 (Where does this come from is it the Viewer ID?) - 3244 PIN (and this I thought the PIN was 3241)= 8163

 

[dommac2000]

In the example 0042343 is the viewer id.

If you remove the two day digits and the checksum you're left with 4234. 3241 is the pin order and comes from a lookup on the vcg Line 26 value (4213).

If you order the viewer id (4234) by the pin order (3241) you get 3244. Then if you lookup 3244 in the 4 line table you get the release code (8163)

Thanks

Thanks appreciated.

head hurting

tried to grasp this last night and still trying just cant seem to make any sense of it at all guess ill get there in the end :eatarrow:

 

[hamba]

Best way to do it is to follow the actual examples given by Nix9
Good Luck!

i have mate but i must be missing the obvious or barking up the wrong tree it will come sooner or later :drink:

I did'nt get home till 9:30pm yesterday. It was only then that I tried my mathematical solution.
It didn't work?
On closer examinination it appears that the digits for 0 and 8 had been transposed?
I tried the computer programme which gave the same answer and didn't work!
Could this be an ECM?

The keygen seemed to working fine yesterday. What was your viewerid and what pin did it give you? (pm me if you don't want to post the codes here)

 

[1234digital]

It was any pin that had a 0 or a 8.ie
7801,8991,7011, 2340,8888 0123,etc

 

[dommac2000]

7801,8991,7011, 2340,8888 0123,etc

Just checked and I don't see any problem :-

For yesterday the calculated table would of been :-

0123456789

2594138706
1483027695
4716350928
1483027695

Pin order: 3421

By running the MHEG I've confirmed that 1560686 = 8947 and 1574007 = 2136 (which is what the keygen gives)

can any1 giv me a simpler way of understanding the handwritten caculation to get your pin cos im really confused thanks a load

 

[nix9]

Just do a few examples, should help. Even make up numbers and then work them out & check with the keygen

 

[desktopfan]

Am I the only one that cant understand this? Been looking at this
today and I cant grasp it. I cant get the keygen to work either cause im in linux. If i could work this out I'd have a go at writing a perl script to work it out

 

[nix9]

Welcome to the forum desktop - try a few examples, that helps alot

 

[desktopfan]

I'll give it a go again tomorrow. Gotta be up for work in 6 hours!

 

[nix9]

Easiest way to thing of it (in programming terms)
Field 23 represent 3 (or 4) function calls. Of 3 functions named 1 2 3. e.g. 333 would be calling function 3 3 times

Fields 24-27 are the passed values along with the (address of) the viewerID

Ignore this all who already understand it (as wouldn't want to confuse!!)

 

[mr3d]

Ok before i start.......do you still need each day the MHG to work this all out! or can you work it out without the MHG

and how can people get the codes for three to four days ahead -

please give me a clue
