I tried to process payment with MasterCard / MIR.
I do read data from VISA successfully after send PDOL, but MS does not requires PDOL.
1st step in transaction:
Select 2PAY.SYS

Step 4:
Read all available data.
[SEND] : 00 B2 01 0C 00
and other sectors
I red all sectors. But there are not tags requires for payment: 9F26 - Application Cryptogram, 9F37 - Unpredictable Number, 9F36 - Transatcion Counter.
To get this tags I could make command Generate AC with CDOL, but how to generate CDOL?
Card says about CDOL1 and CDOL2. And CDOL1 requires tags that card generate itself.
Card answers, contains CDOL1 and CDOL2:
70 81 A0 57 13 55 45 46 77 77 25 42 79 D2 01 12 01 58 11 10 00 00 79 0F 5A 08 55 45 46 77 77 25 42 79 5F 24 03 20 11 30 5F 25 03 17 11 01 5F 28 02 06 43 5F 34 01 01 8C 21 9F 02 06 9F 03 06 9F 1A 02 95 05 5F 2A 02 9A 03 9C 01 9F 37 04 9F 35 01 9F 45 02 9F 4C 08 9F 34 03 8D 0C 91 0A 8A 02 95 05 9F 37 04 9F 4C 08 8E 0E 00 00 00 00 00 00 00 00 42 03 1E 03 1F 03 9F 07 02 3D 00 9F 08 02 00 02 9F 0D 05 B4 50 84 00 00 9F 0E 05 00 00 00 00 00 9F 0F 05 B4 70 84 80 00 9F 42 02 06 43 9F 4A 01 82 90 00
How generate offline limit transaction using paypass? How to do Generate AC?
Thank you!
CDOL1 and CDOL2 splits like below. Tag and its lengths. You are supposed to provide the data alone in the same order and size as you would for PDOL. In the below case, apart from two towards the bottom, rest all are available in the terminal ready to use.
CDOL1
9F02 06 //transaction amount
9F03 06 //other amount, cashback
9F1A 02 //termial country
95 05 //TVR terminal has arrived after terminal risk management
5F2A 02 //currency code
9A 03 //Transaction date
9C 01 //transaction type
9F37 04 //unpredictable number
9F35 01 //terminal type
9F45 02 //data Authentication code from Transaction Related Data ODA
9F4C 08 //icc dynamic number from Transaction Related Data ODA
9F34 03 //cvm results
CDOL2
91 0A //issuer authentication data
8A 02 //ARC
95 05 //TVR
9F37 04 //unpredictable number
9F4C 08 //icc dynamic number
9F26 and 9F36 will be returned by the card in response to your GEN AC.
9F37 is generated by the terminal.

This is part of the file which made me believe it is a rar file. I tried using xxd with the -r option to no avail.
I tried the solution from here but it also didn't work.
Any ideas?
To solve my own question, and for future reference.
Use vim's visual block select to copy just the hex values into 'justhexvalues.txt'.
Then use xxd:
xxd -r -p justhexvalues.txt answer.rar
That was it.
I have this code in hexadecimal bytes:
01 00 08 20 00 00 09 20 05 00 02 20 0c 00 00 00 03 00 02 11 20 48 09 01
01 00 08 21 03 00 00 08 1a 00 22 01 12 20 00 00 0c 00 00 00
How can I tell the endianmess of this?
When I plug it into here: https://onlinedisassembler.com/odaweb/, I get this code:
Where does the first line in binary 20080001 come from in the hexadecimal?
This is in little endianness. When I change it to big endianness, I get:
Is the above code wrong?
My program was able to craft and send raw transactions to geth v1.3.3 before, but after I upgrade to geth v1.4.0, calling sendRawTransaction over RPC always returns invalid sender error.
Is transaction serialization (i.e. RLP) changed somehow from v1.3.3 to v1.4.0? Here is a dump of by raw transaction that triggers an invalid user error:

I believe the JSON RPC stuff changed in geth v1.4.0. I can't tell why this is happening without seeing the full sendRawTransaction you are calling but check out the docs: https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_sendtransaction
Also, this should be migrated to https://ethereum.stackexchange.com/

How can I convert this back to a CSS text file?
I have a binary file that I want to open as (or to convert to) jpeg image.
The file is only supposed by me to be a jpeg within a binary format, therefore I include a part of it so that You can tell me if I'm wrong ('cause unfortunately I never saw one of those before):

How can I convert it to jpeg to view its content (that is supposed to be an image)?
Is this conversion necessary or would You reccomend a software that can open it as I like?
I hope someone could help me, thanks in advance.
ANSWER
(As I can't answer my own question right now, I'm doing it here...)
At the end I came up with a solution thanks to the input information of unwind.
I downloaded HEX editor (http://www.hhdsoftware.com/free-hex-editor) to edit my binary file. Then I searched for the string where the 0xff 0xd8 was (in may case in line 0000000288). This is supposed to be the beginning of a JPEG file. Then I deleted everything that came before of that (also the six pair of zeros within the same line). Then I saved m edits and tried again to open it with an image processing program (in my case, I'm usin ENVI), and....IT WORKS! Now the binary file is red as an image file!
The problem now is that I have plenty of those files (302), and I need to edit all of them. Moreover, they each contain more than one jpeg, so I need to modify each one ore times. Guess I need to improve my programming knowledge...
Well, according to this page JPEG files begin with the byte pair 0xff 0xd8, so you could search forwards for that sequence, and throw away the data before it.
In your file, it happens on the line starting 0000000288.
