What do we have here?

It looks like we have 2 different items here. The first block of what looks like it could be hex or hex encoded data and the last looks like some kind of script.

The first block

The first thing I noticed about the code is that it ends with either 3d3d or 3d3d3d if you allow it to wrap to the bottom like. So, what encoding scheme do we know that pads the end of a block with 2 characters? That's right, base64. If you take 3d3d in hex and convert it to ASCII you get ==, the typical padding for base64.

Next, I took the string from the shirt and converted it from hex to ASCII

5955677851555a44643149766257396a4c6d3570596d5630633246774c7938366348523061413d3d

which converts to

YUgxQUZDd1IvbW9jLm5pYmV0c2FwLy86cHR0aA==

I then took this base64 encoded string and decoded it using http://www.opinionatedgeek.com/dotnet/tools/base64decode/ . This gave me an ASCII string.

Ahh, now we're getting somewhere. We have a URL that has been reversed. It's  short, and fairly obviously a pastebin.com url so I keyed it in by hand to my browser.

http://pastebin.com/RwCFA1Ha

This leads us to another block of base64 encoded text.

Let's put this through our decoder and see what we get. In this case it is a binary file of some sort. Because this is just a binary blob how do we know what to open it with? In this case I used the 'files' command on Linux which will look at a file and tell you what it is based on the 'magic numbers' or typical file headers to tell you what type of file it is. In this case it is

DecodedBase64 (1).bin: gzip compressed data, was "jlchal.txt", from Unix, last modified: Tue Apr 10 16:14:40 2012

I renamed the file and put it through gunzip and ended up with an ASCII text file.

In case that doesn't render in your browser, here's what it looks like.

[caption id="attachment_289" align="alignnone" width="234" caption="Who the hell is this guy"][/caption]

It's at this point that I've hit a bit of a wall. I have no idea who this guy is, although he looks kind of like Art Garfunkel and now that's all I can see when I look at it. The filename looks like it might be a clue, but again I do not recognise the name jlchal, or the initials JL if this is a challenge. It could refer to J.L Villar who has done some work in cryptography, however he does not look like this guy ;)

What do we have then?

I have drilled down the levels and ended up with an ASCII art picture of some guy I don't recognise and a filename that may be a clue. If anyone has any suggestions then I'd love to hear them.

How about the last line?

The last line consists of

3d { print 0x$444 ); { iff beep }

I'm assuming the 3d belongs to this line, as if you add it to the block of text above it makes it invalid base64.

We have two executable blocks here, and this is where my lack of shell scripting is starting to be a problem. Print 0x should print a hex value, but the $ seems to indicate that it's using an environment variable. The presence of the beep seems to indicate that it's a bash environment but I cannot find the iff (if and only if) command anywhere inside bash.

So I didn't get very far at all. Time for some more hacking to see if I can tease any more information out of it.

UPDATE(2/5)

Twitter has informed me that JL is in fact @jameslyne, the creator of the challenge.
