Convert larger value hex string into bytes using java
Use method 2 and don't worry about the negative values in your byte array. Bytes are signed in java, so if you want to process your bytes as 0 to 255 instead of -128 to 127, AND each byte against 0xFF. This will promote the byte to an integer and...
Using Scanner to display entire line if the line contains any part of a string match (Java)

How to parse C array in python
How about just: [re.sub("/\*.+\*/", "", m).replace('\n', '').strip() for m in re.findall("{(.+?)};", c_file_as_string, re.S)] ...
Converting .raw file into Hex
The problem is you pass the name of the file to hexdump() which treats it like data. The following corrects that and applies other relatively minor fixes to your code (and seems to work in my limited testing): try: xrange except NameError: # Python3 xrange = range def hexdump(filename, length=16,...
How to parse hex dump
This is just an idea to get you started since I'm not entirely sure what you need. The basic idea is that read_byte returns the next two-digit hex value as a byte and also returns its address. #include <stdio.h> #include <stdlib.h> #define FILE_NAME "UA201_dump.txt" void err(char *msg) { fprintf(stderr, "Error:...
Read hex data into less
I don't understand the details of the example, but I think you want to put the less outside of the loop, like this: while read -u 10 p || [[ -n $p ]]; do hexdump -e '/4 "%08x\n"' {$p} done 10</Users/masi/Dropbox/7-8\:2015/r3.raw | less -s -M +Gg ...
Hex Dump (byte array) with non standard Characters to int
python,hex,byte,bytearray,hexdump
The É is hex C9. 0x5AC9 is 23241 If it were È (which is hex C8) you would get 23240. [See http://www.pjb.com.au/comp/diacritics.html] It looks like sometime, when the hex can be interpreted as a printable character like É, that character is output instead of the hex. In the case "#00#00#5AÉ#00"...
Recursively search directory of binary files for hexadecimal sequence?
shell,zsh,binaryfiles,hexdump,find-util
IF: you have GNU grep AND the hex bytes you search for NEVER contain newlines (0xa)[1] If they contain NUL (0x), you must provide the grep search string via a file (-f) rather than by direct argument. the following command would get you there, using the example of searching for...
Deciphering some Hexcode
Just a wild guess, but maybe it's going to be useful. If you interpret the numbers as a little-endian 32-bit integer, then: 0x0001c050 = 114768 in decimal. Also notice how a difference of one in the numbers means one day of difference. So one in the date means one day....
saving hexdump(packet) to list in scapy
The byte content of the packet may be accessed by invoking str(packet), as follows: content = str(packet) # decoded hex string, such as '\xde\xad\xbe\xef' print content for byte in content: pass # do something with byte EDIT - This answer specifies how this can be converted to a byte array,...
Output 64 bit integer with hexdump
c++,binary,64bit,reverse-engineering,hexdump
Our final workaround reads as follows: x=`hexdump -n 8 -e '2/4 "%08X " "\n"' {FILENAME} | awk 'BEGIN{printf "0x"}{print $2$1}'` echo $(($x)) Explaination for each part: Extract the eight bytes of the 64-bit integer value from file {FILENAME} as two four byte chunks printed as hexadecimal encoded values. hexdump -n...
How to compile Intel x86 assembly code to get hex dump?
To get only a hex-dump you don't need a valid executable. In your case (no relocations) I see no problems to assemble the code at home with your assembler on your operating system, get the hex-dump and use it on the target system. Just take care of the architecture (i386...
python2 vs. python3 in string containing hexadecimal
Python 2’s plain '-quoted strings represent strings of bytes; Python 3’s represent strings of characters. The equivalents in the opposite language are bytes (b'literal') and unicode (u'literal'), respectively. % python3 -c "from sys import stdout; stdout.buffer.write(b'a' * 72 + b'\xff\xbe\xbf\xff\n')" | hexdump -x ...
MFC read file and display it as HEX (hexdump)
Here is a solution with owner draw ListBox (size=fixed-sized, sort=false) class CListHex : public CListBox { public: std::vector<BYTE> Buffer; CRect SaveItemRect; CEdit Edit; int Index; void setup() { if (Edit.m_hWnd && IsWindow(Edit.m_hWnd)) return; Edit.Create(WS_CHILD | WS_BORDER | ES_CENTER, CRect(0, 0, 0, 0), this, 1); Edit.SetFont(GetFont()); Edit.SetLimitText(2); SetItemHeight(0, 21); } void...
Binary to CSV record Converstion
python,csv,binary,data-conversion,hexdump
As already mentioned, without knowing the binary protocol it will be difficult to guess the exact encoding that is being used. There may be special case logic that is not apparent in the given data. It would be useful to know the name of the 3rd party application or a...
How do you Pipe hex data directly to bc and converting it to binary - cleanly?
I think this does what you want. { echo "obase=2; ibase=16"; xxd -c 32 -u -p file.bin; } | bc It just feeds both the settings and the streamed file contents to bc with a brace list. The -u flag to xxd makes it output upper case hex letters....
How to decipher/interpret the contents of a file as shown in a Hex editor?
sql-server-ce,hex,hexdump,hex-editors
The data is stored little-endian. Both show 0x73616261, meaning both are SQL CE version 2.0 database files.
hexdump and reading binary files to text
The format option includes 3 items: Iteration count: It is count for how many times format option would be applied Byte count: It is count of bytes which would be processed and displayed by hexdump on each iteration of format option applied Format option: It is option of hexdump that...
