I am trying to import a key into the card, but it is giving response as 6F00 (UNKNOWN ERROR).The procedure i followed to import a key is
Load the (MUSCLE) applet
Initialize the applet
Verify the pin
create the object with id (FF FF FF FE):
-> B0 5A 00 00 0E FF FF FF FE 00 00 00 44 00 00 00 00 00 00 00
<- 90 00
write into the object
-> B0 54 00 00 8D FF FF FF FE 00 00 00 00 84 00 01 00 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
<- 90 00
Import key
-> B0 32 04 00 07 00 00 FF FF 00 00 00 00
<- 6F 00
Please provide a solution for the above problem.
If you are still looking for the solution: 7 bytes seems to be a bit high for importing a key... ;)
The ACL in the data block is only six bytes, so this might cause your error. The following "optional parameters" are AFAIK completely unused.

Sample of my df is:

+------------------------------------------------------------------------------------------------------------------+
with these schema (df.printSchema())
|-- id: int (nullable = true)
|-- binary_col: binary (nullable = true)
And I want to filter only the values with [08 01 10 0D 00 0E CC 93 01 00 00 00 01 00 00 00 00 00 00 00 80 FF BF 40 00 00 00 00 00 00 F0 3F BE 2B 00 00] (It doesn't work filtering id=1 because there are other ids in the df)
I've tried to cast binary to bigint to filter later like here: Spark: cast bytearray to bigint
by doing df.withColumn('casted_bin', F.conv(F.hex(F.col("binary_col")), 16, 10).cast("bigint")).show(truncate=False) but it didn't work.
How can I filter any kind of binary data type?
Note: I had asked previously here (How to filter Pyspark column with binary data type?) but it was a very simple binary data and the answer generated the binary from a numeric value while now I don't know how to generate the numeric value.
I'm trying to figure out how to pull the data listed below as "<![CDATA['Sec']]>" or trying to extract "Sec" from it.
This is how i'm grabing the other variables.
foreach (#L5Xfiles) {
my $input="RSL_Export/"."$_";
open(my $data, '<', $input) or die "Can't open < $input: $! \n";
my $parser = XML::LibXML->new();
my $doc = $parser->parse_file($input);
foreach my $tag ($doc ->findnodes('//Tag')) {
my $atag = $tag->getAttribute('DataType');
if (defined($atag) && $atag =~ /Timer_Tag/) {
my $name=$tag->getAttribute('Name');
my $out=$tag->findvalue('Data/Structure/StructureMember[#Name="SP"]/DataValueMember[#Name="Out"]/#Value');
my $secmin=$tag->findvalue('Data/Structure/DataValueMember[#Name="UnitsSelect"]/#Value');
my $min=$tag->findvalue('Data/Structure/StructureMember[#Name="SP"]/StructureMember[#Name="EU"]/DataValueMember[#Name="Min"]/#Value');
my $max=$tag->findvalue('Data/Structure/StructureMember[#Name="SP"]/StructureMember[#Name="EU"]/DataValueMember[#Name="Max"]/#Value');
my $name_L0 = $name;
$name =~ s/_/\\_/g;
$secmin =~ s/0/Sec/g;
$secmin =~ s/1/Min/g;
$timers{'TimerConfig'}{'TimerConfig'}{$name}=$out . " " . $secmin;
my $RSLTAG = $name_L0;
$TimerTestTags{$RSLTAG} ={RSLTAG=>$RSLTAG,L0=>$name_L0,L1=>'',L2=>'',L0_Type=>$atag,L1_Type=>'',L2_Type=>'',SP=>$out,Unit=>$secmin,Min=>$min,Max=>$max};
}
}
}

I've captured the TCP traffic between the control box and the LED drivers, but I'm not sure what to make of it.
Seems the first string sent is the value, and the second string is some kind of confirmation, or go ahead and do it message.
But how would I send an arbitrary value like 33%
Does anyone see an obvious way to convert this data?
First section below sets the brightness to 100%, second to 75% and so on.

I'm trying to reverse engineer the CAN bus codes generated by the steering wheel of a car. I'm interested in a single message, the one that holds the information about what button of the steering wheel has been pressed. I have done that for many different cars but this one is special (?)
I found the message that holds the data has for ID 0x3D4. So I logged this specific message many times with/without a different combination of the steering wheel buttons.
The way car works (most of the time) is that a single bit will toggle from 0 to 1 when a button is held down. And go back to 0 when the button is released. This message has a DLC of 8 so there would be potentially enough room for 64 buttons.
Now for this car, they have used 4 bits of the second byte for a counter counting from 0 to F. The first byte is the one that is causing a problem. I don't understand how it is generated. It seems to be dependant on the value of the other bytes but does not follow a standard CRC algo... It seems that it also depends on the position of the bytes... Pressing on buttons in the car will change a bit in the data which then changes the value of the first byte. If I generate a fake command to the car without changing the first byte, the car will not react to it.
I would like to find how this first byte is generated so I can generate it myself.
The DLC: 8

Thanks!
If your goal is to send an arbitrary known code to the car, a simple way is to use a map to store all the valid 1st bytes, and send it accordingly.
If your goal is to utilize those other bits previously not used (~5 bytes of them), then unfortunately it is not possible from the data you provided. One reason is that there is no way for us to know the ordering of the ~40 currently unused bits even if we knew the algorithm used to generate the 1st byte.
The space of 1 byte values is small, only 256. For any code that you want to send, you could just try 256 times each with a different 1st byte. If any one does anything, then it's probably it. If none does, then maybe that code is invalid altogether?
I can say what it is not. The first byte is not a CRC, nor is it any linear combination of the provided remaining bits over GF(2). It may be some other function of the following bits/bytes.
Have a file that appears to have plaintext headers in them that I would like to extract and convert to plaintext.
Using HEXedit, this is what I'm seeing, which is in a file:
3a40 - 31 65 33 38 00 00 00 00 00 00 00 00 00 00 00 00 - 1e38............

3a60 - 78 00 74 00 2f 00 61 00 73 00 63 00 69 00 69 00 - x.t./.a.s.c.i.i.
3a70 - 00 00 18 00 61 00 66 00 66 00 79 00 6d 00 65 00 - ....a.f.f.y.m.e

3aa0 - 64 00 65 00 00 00 64 00 40 00 35 00 32 00 30 00 - d.e...d.#.5.2.0.
3ab0 - 38 00 32 00 36 00 30 00 30 00 39 00 31 00 30 00 - 8.2.6.0.0.9.1.0.
3ac0 - 37 00 30 00 36 00 31 00 31 00 31 00 38 00 31 00 - 7.0.6.1.1.1.8.1.
3ad0 - 31 00 34 00 31 00 32 00 31 00 33 00 34 00 35 00 - 1.4.1.2.1.3.4.5.

3b00 - 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0a 00 - ................
and this is the output I'd like to get:
text/ascii affymetrix-array-barcode d#52082600910706111811412134550989
Try with the iconv command. Something like this should work:
tail -c +6 input.txt | iconv -f UTF16 -t ASCII >output.txt
Then split on the null bytes.
Granted, I'm no wiz, but this does the job if all your files look very similar to the one you just posted:
use strict;
open FILE, 'file.dat';
binmode FILE;
my ($chunk, $buf, $n);
seek FILE, 28, 0;
while (($n=read FILE, $chunk, 16)) { $buf .= $chunk; }
my #s=split(/\0\0/, $buf, 4);
print "$s[0] $s[1] $s[2]\n";
close (FILE);
A perl solution might be interesting, but wouldn't the unix strings command give you the plaintext portion of the file?
