Binary

[MDC]

Hi
sorry if this sounds completely stupid but I found some binary code on an A4 sheet of paper at work and wondered how or if I could figure out what it does. Is there a programme I can put binary into and see what happens or do I need to run it against something?

I have no idea what it does or who left it, but it looks like it does something.

As I used to lecture to students, a binary number by itself can mean anything. It may be an unsigned integer, a 2's complement integer, a fixed-point number, a floating-point number, ASCII characters, EBCDIC characters, bit-mapped graphics, machine language for who-knows-which computer, or anything else. Binary numbers are meaningless until you decide how to interpret them.

Some formats are readily identifiable as ASCII or a particular machine language. For example, ASCII in 8-bit bytes is pretty obvious since most values are 0x20 - 0x7E (space through ~), with occasional 0x0A (LF). ARM assembly language will have 32-bit values most of which start with 0xE (unconditional execution).

I would LOVE to find a sheet of A4 with binary on it . It's a puzzle. Enjoy it

They seem to come in pairs of binary code and range from 0001 to 1111.

A contest! Give us the first N of them and give prizes to whomever calculates N+1 first

For a good read, I recommend Jules Verne's The Cryptogram, where a man's life depends on decrypting a letter.

@adriley
nice one.

I'm guessing - 20 rows of 8 pairs, starts eb 04 af c2 bf a3 81 ec?
That'll be GCHQ

No, just a load of 1's and 0's. and there aren't that many as you say.

Here's one for you all.. The networking guru's should work this out easily...
Can you convert binary octets into decimal? This should give you an ip address that I just randomly made up

01110111
01010001
11110111
00011000

There is no prize for this.

its the quote converted to ascii binary...i had to put spaces in between because it posted as 1 long string , way off the page

[sh4d0w0lf]

wrong answer. Its supposed to be a computer ip address.

the correct awnser is:
119.81.247.24

The working out:

128 64 32 16 8 4 2 1
----------------------------------------------------------
0 1 1 1 0 1 1 1
0 1 0 1 0 0 0 1
