Is it possible to generate Indala UID from number printed on badges?

I am investigating some Indala 125MHz cards.  I am told that these are basic Indala cards (not encrypted Indala Flexsecure).  I am able to losamples, indalademod, and losim these cards successfully.  There seems to be a correlation between the last 5 digits printed on the card and the UID that proxmark3 detects with indalademod, because when I scan the card on the reader I can see the hex value of the printed ID transmitted over the network (ie the reader grabs the UID, converts it to hex(printed ID), and transmits it on the network).  I would love to be able to arbitrarily convert printed IDs to encoded UIDs, bypassing the need for physical access to someone's card for cloning, but so far I've been unable to reverse-engineer the algorithm that converts the printed ID to the UID. 

Does anyone know how, or if this is even possible?  Below are some sample reads.  My goal is to work this backwards, starting with printID and calculating the UID.   A command such as `indalasim {facility ID} {card ID}` would be the ideal end state, but the algorithm for converting between these IDs would be an awesome start in that direction.

Re: Is it possible to generate Indala UID from number printed on badges?

asper, no offense because I usually hold your posts in high regard, but those links have little to nothing to do with the indala scatter bit format sentinel outlined above.  this can be used to get the facility code and card number of an indala card from the pm3's indala read ID#.  it can also be used to know how to program a sequence of indala cards or "find the next card".

app_o1, as far as the checksum, I have a guess but haven't been able to confirm it.  Maybe someone else knows for sure?

Sorry marshmellow, i don't have those kind of cards (it was only a suggestion, maybe those links can be useful for something else); no intention to low considerate  your work ! wink

Re: Is it possible to generate Indala UID from number printed on badges?

smile  no worries asper, I just didn't want anyone confusing standard 26 bit formats with indala's.  And Sentinel did all the work here.  now if only I had lots of free time to figure out the proxmark's programming better so I could add to the read commands so it would detect and output the correct values for the different formats...  maybe one of these days...

And what about P1 & P2 ?
As far as I understand, P1 is for the Xs and P2 is the one for the Ys ?
But I have one case where is doesn't "work" that way...

P1 and P2 follow the same rule as standard Wigand 26bit format - see asper's links above.

Re: Is it possible to generate Indala UID from number printed on badges?

any luck figuring out the checksum calculation for checksums 1 and 2?

regarding P1 and P2 calculation, i can only speak to HID standard formats:
HID 26 bit, parity is still beginning and end bits leaving 24 bits remaining, P1 is even parity calculated off the first 12 bits, P2 is odd parity calculated off the last 12 bits
HID 35 bit, parity is again the beginning and end bits, leaving 33 bits remaining, P1 is even parity from the first 17 bits, while P2 is odd parity from the last 16 bits. The exception is that if the card's ID number is too large to fit inside 16 bits, shift the place where you calculate the parity. (P1 from the first 16 bits, and P2 from the last 17 bits, for instance, with facility and ID residing in the same.)

Re: Is it possible to generate Indala UID from number printed on badges?

Sorry, I've been very busy.  I meant to note my guess at the checksums.
Add up all the Even "Y" values (like y12) and if that sum is even then the checksum = 10 if it is odd the checksum = 01

app_o1 can you confirm if this works on your cards?

Re: Is it possible to generate Indala UID from number printed on badges?

I ended up with the same thing. It worked in most cases.
BUT, I got 2 cases where it gives not 10 nor 01 but 00.

Although, those two bad boys are from the same location (supposedly the same FAC) the UID does not give me the same FAC... So I am guessing it is a "special" case...

But anyway, UID is what I read from the tag ! And it gave 00 two times... So I guess there is also a "00" possibility...

I found a few more cards. And it actually doesn't seem to be working all the time.

Re: Is it possible to generate Indala UID from number printed on badges?

I did see those, however, I've noticed with the proxmark that depending on distance and antenna tuning you may see slightly different UID's returned for the same card.  That slight difference has made some cards not pass the parity in my testing.  But a second or third read with some variation usually produces the proper card UID.
Since I do not physically have the cards mentioned I cannot re-read them to test the accuracy of the read.  So I cannot say for sure this proves our calculation wrong.

Re: Is it possible to generate Indala UID from number printed on badges?

There may be different indala formats within the 26 bit format with different Checksums.  The format number 40134 is just the standard 26 bit indala format and is, what I believe to be, the most common and the one I've seen/tested the most.  The format number is marked on the label on the box of cards from the factory (now HID).

Re: Is it possible to generate Indala UID from number printed on badges?

Correspondence table was calculated using the card Temik 5557. I recorded on the card all 0 and one 1. Then brought a card to the reader and looked where there is one. I had to make a reader who reads all standards emmarin, Hid, motorola,  based MSP430F2132. I could not understand how to calculate the checksum bits in the Indala, so just ignore them

Re: Is it possible to generate Indala UID from number printed on badges?

"ignore them" ? Okay...
But will it work on door if the checksum is "wrong" ?

It is just 00 or 01 or 11 or 10...


i can try on RL and see if it works whatever these 2 bits are.

Re: Is it possible to generate Indala UID from number printed on badges?

reader (FP3517A), of course, does not ignore the checksum, and nothing will print if it is damaged. Unfortunately, I searched through the entire internet, and found nothing about Indalа sad  and my client does not know that I do not check the checksum smile  main task was to clone reader motorola

Re: Is it possible to generate Indala UID from number printed on badges?

@ Sentinel
I believe the checksum for Indala 26 bit is calculated by adding together y2,y4,y7,y8,y10,y11,y14,y16 and if sum is even then checksum is "10", else "01"

However there is another format from Keri that is almost identical to Indala 26 except for the checksums - same calculation just uses "11" in place of "10" and "00" in place of "01"  (and a couple static bits are changed from 0 to 1)

as far as the Guardall G-Prox II (aka Chubb) I have gotten nowhere with this (I don't think I have the cards even anymore)  I do have some card numbers and binary readouts, but no way to convert between the two.

Any public solution to this topic? Is there any "official" documentation for Indala at all?

Re: Is it possible to generate Indala UID from number printed on badges?

there are multiple (hundreds possibly) different indala "formats" or bit scrambles.  some are known and outlined on this topic and others.  others are not known. 

there will be no official documentation on format from indala or hid as that is their claim to security.

Is it just bit scrambling, or is there a chance for more sophisticated approach? I've heard something about encryption, but this is said to be 'indala confidential'. The only thing I know is you have some 'reader configuration cards' which you use to configure brand new reader (these cards are actually available to me). After configuring reader it starts to scramble/encrypt? card numbers and does not read specific cards - probably outsite given FCs, but not sure about this. I've heard that one of these cards set up some kind of encryption key into reader (I don't expect this might be true). Actually these configuration cards are in my hands, but it didn't help me either. Do you think there is a chance to achieve some progress in this issue using proxmark? I haven't bought it yet since I am not sure that helps.

Re: Is it possible to generate Indala UID from number printed on badges?

how about you dump the "reader configuration card",  so we can have a look at its contents and take it from there.

Please see this post http://www.proxmark.org/forum/viewtopic … 279#p18279. I don't know what those cards contain and if it can be something customer-sensitive, so I can't post full content here.

Re: Is it possible to generate Indala UID from number printed on badges?

that is too little data to be able to answer any questions.

What was the settings before?  What did it become afterwards?
documentation?

Re: Is it possible to generate Indala UID from number printed on badges?

I have no idea about original reader settings, probably factory defaults. I have also no idea about parameters that can be changed and its possible values (and what those cards actually do to card numbers). No documentation, just nothing. I can send you config cards data if you are interested, what is your email?

Re: Is it possible to generate Indala UID from number printed on badges?

Hello friends,

I would like to encode ATA5577 chips to emulate INDALA 26 bits card.

Then, as a specification,  I would like to prepare an excel sheet with bits from 45 to 1 :
45 44 43 .....26(cs)25  ....2 1(CS)  (25 to 1 is the so called wiegand part)
TO :
Block 1 Block 2 Block 0

I have done this in the past for HID 26/35/37 bits, this is very usefull to check card encodings.
I'm missing :

BLOCK ZERO

But i'm alos unclear with 44 to 1 follwoing this topic.

Thanks a lot.

I'm sure I have been pretty unclear :-)

Re: Is it possible to generate Indala UID from number printed on badges?

Hello,

I've made the excel spread sheet to transform bits 1 to 35 into 8 bits for Facility and 16 bits for card number.

I have been able to check the 2 first cards then validate that I didn"t make mistakes  :

0000000000000000000000000000011110010010100010001011000010001101 x79288B08D x020 x2355 09045
0000000000000000000000000000010100000111101110110101000100001101 x507bb510d x081 xF893 63635
and found x020 and x2355 then x081 and xF893. Good.

But when I tried the following cards, I did not find the same FC and Card numbers that is displayed on this topic.
Typically, I applied the same permutation on :
0000000000000000000000000000011110010010100010000010000100001101 x79288210D x130 x44A8 17576

I found 0x021 decimal for Facility code (not 130 Dec) and x2241  (not44A8 Hex) for card number.
No way to get x130 (82 hex) that would mean binary 10000010 for facility code, the first 1 being X1, X1 being in position 26 that is a zero. Too bad.

How could it work for 2 cards and not with the others ? how have the card numbers been generated  for the third to 6 th cards from the list ?

Thanks for double checking.
My spread sheet is available to help for sure.
Thanks a lot and best regards.
John.

Re: Is it possible to generate Indala UID from number printed on badges?

@Iceman and Marshmellow,

I have built a parser (as 6 matrix) on Excel for the six cards of this thread and there is no solution for a single permutation table between what is read and the Xi-i and Yi. If you have more cards numbers and traces.
About this thread and refering to Sentinel, no 'hero' yet ...
Best regards.

Re: Is it possible to generate Indala UID from number printed on badges?

Indala has many many formats, all with different scramble patterns.  You will not find one solution to all of them.
