I have this binary file on my Linux system...
udit@udit-Dabba ~ $ cat file.enc
Salted__s�bO��<0�F���Jw!���]�:`C�LKȆ�l
Using the hexdump command, I see its information like this:
udit@udit-Dabba ~ $ hexdump -C file.enc
00000000 53 61 6c 74 65 64 5f 5f 1b 73 a1 62 4f 15 be f6 |Salted__.s.bO...|
00000010 3c 30 cc 46 ee 10 13 11 84 bf 4a 77 21 a4 84 99 |<0.F......Jw!...|
00000020 0e 5d ef 11 18 3a 60 43 a0 4c 4b 1e c8 86 e6 6c |.]...:`C.LK....l|
00000030
Now I am given a file on some other system whose contents are like this:
53 61 6c 74 65 64 5f 5f 1b 73 a1 62 4f 15 be f6
3c 30 cc 46 ee 10 13 11 84 bf 4a 77 21 a4 84 99
0e 5d ef 11 18 3a 60 43 a0 4c 4b 1e c8 86 e6 6c
And I need to find out that same exact binary information from this hexdump.
How can I proceed for that?
If there isn't any switch for that then C code will also work fine.
(But a Linux command with some switch is preferable)
Limitation:
The binary information in the file is output of an encryption algorithm, so contents should exactly match...
As @user786653 suggested, use the xxd(1) program:
xxd -r -p input.txt output.bin
