I'm new to this StackExchange - I'm more active on programming stack exchanges. So here's a computer-themed puzzle:

4K5L3RdR-PASTE
Find the code (6 numbers)

That's it. I'll leave you with one clue - The title.

  • $\begingroup$ Unfortunately, I can't find any tags that suit what this question is about exactly. $\endgroup$ Commented Oct 31, 2016 at 5:20
  • $\begingroup$ It's quite possible that there is no other needed tags too. Only you know for now ;P. Also although it was needed to say the goal is to find the code, saying how long and what kind of characters are in it was not. It all depends on how easy you want your puzzle to be. $\endgroup$ Commented Oct 31, 2016 at 5:24
  • $\begingroup$ It really doesn't matter how long the code is. You find the entire thing at once. $\endgroup$ Commented Oct 31, 2016 at 5:25

The answer could have been

$941184$

But is actually

$1238476$

Because

If you go to pastebin.com/4K5L3RdR you find:

89 50 4e 47 0d 0a 1a 0a 00 00 00 0d 49 48 44 52
00 00 00 22 00 00 00 16 08 06 00 00 00 a5 ac 4e
79 00 00 00 79 49 44 41 54 78 da 63 61 60 60 f8
cf 00 01 8c-50 1a c6 47 07 d4 96 47 e1 b3 30 0c
12 c0 82 c7 e5 0c 38 7c 48 48 9e d8 10 22 e8 90
41 13 22 ff 89 d4 fb 9f 9a f2 83 3a 44 70 a5 05
6a e5 22 ac 69 6c 48 84 c8 7f 4a 72 01 09 ea 06
5f 1a 61 24 33 6d 90 2b 8f 55 fd a0 0a 11 4a eb
0e 9a 27 d6 01 4f 23 74 09 81 21 55 d7 90 5a ae
8c dc 10 21 b5 64 1d 79 69 64 78 86 08 00 ce b8
19 58 95 d4 60 0b 00 00 00 2d 74 45 58 74 53 6f
66 74 77 61 72 65 00 62 79 2e 62 6c 6f 6f 64 64
79 2e 63 72 79 70 74 6f 2e 69 6d 61 67 65 2e 50
4e 47 32 34 45 6e 63 6f 64 65 72 a8 06 7f ee 00
00 00 00 49 45 4e 44 ae 42 60 82
Which looks like hexadecimal (except for a lone '-', which I presume is a typo.

converting that to bytes one sees that it starts with
\x89PNG\r\n

and ends with
tEXtSoftware\x00by.blooddy.crypto.image.PNG24Encoder¨\x06\x7fî\x00\x00\x00\x00IEND®B`\x82

Writing it to a file with a .png extension yields the image:
numbers

Originally it was stated the number we sought would have six digits, and since this was not a six digit number I presumed that we needed to multiply, which gave $941184$, however it was not the case.

Question at this stage can be said to be too braod with multiple answers

Here is one -

Say A=1, B=2... Performing multiplication gives 171072. i.e. taking only characters Which are 6 digits. 11*12*18*4*18(KLRDR)

    $\begingroup$ Might look broad, but I have an inkling my answer is more fitting. $\endgroup$ Commented Oct 31, 2016 at 6:42
  • $\begingroup$ Yes. Posted almost at the same time. Though not sure how the any of the answer can relate to the title. $\endgroup$
