Hex Online Teks Decoder

I have ABC123EFFF.

I want to have 001010101111000001001000111110111111111111 (i.e. binary repr. with, say, 42 digits and leading zeroes).

How?

I have the following code...

int Val=-32768;String Hex=Integer.toHexString(Val);

This equates to ffff8000

int FirstAttempt=Integer.parseInt(Hex,16); // Error "Invalid Int"int SecondAttempt=Integer.decode("0x"+Hex);  // Error "Invalid Int"

So, initially, it converts the value -32768 into a hex string ffff8000, but then it can't convert the hex string back into an Integer.

In .Net it works as I'd expect, and returns -32768.

I know that I could write my own little method to convert this myself, but I'm just wondering if I'm missing something, or if this is genuinely a bug?

I'm trying to decode hex string to binary values. I found this below command on internet to get it done,

string_bin = string_1.decode('hex')

but I got error saying

'str' object has no attrubute 'decode'

I'm using python v3.4.1

I want to take an integer (that will be <= 255), to a hex string representation

e.g.: I want to pass in 65 and get out '\x41', or 255 and get '\xff'.

I've tried doing this with the struct.pack('c',65), but that chokes on anything above 9 since it wants to take in a single character string.

After 5 hours of trying to get it to work, I decided to ask for help. My problem is PHP convert the different string to hex than MSSQL.

STRING

đžćčšđđ

PHP

bin2hex($data) // C491C5BEC487C48DC5A1C491C491

MSSQL

CAST('đžćčšđđ' as varbinary) // F09EE6E89AF0F0

PHP result needs to be as MSSQL. What can I do to a solved problem?

EDIT 1

Almost got it to work correct, still 2 char is wrong

$unpacked = unpack('H*hex', mb_convert_encoding($data,'ISO-8859-2')); // F0BEE6E8B9F0F0
