Anyway, once you get crypt.c and the hex contents of the "key" file, while you don't have the full crypt.c program you can clearly see that the crypt function XORs the text with the key:

unsigned char key[] = "IFNWOUVYZNALWPFORUCYANAKCIZYQKAPZIWYTOMICUAHQIDFYSNFJKDUAJWKFJAUYZJANK";
void crypt (char *text, int length)
{
    int i;
    for (i = 0; i < length; i++)
        text[i] ^= key[i];
}

Since XOR is commutative and we have the XORed text as well as the original key from crypt.c, you can use a simple program to (de)crypt it:

public class Decrypt {
    public static void main(String[] args) {
        String key = "IFNWOUVYZNALWPFORUCYANAKCIZYQKAPZIWYTOMICUAHQIDFYSNFJKDUAJWKFJAUYZJANK";
        String text = "# 3o4v	n5#wwu,7a:-e-,.y&\"58z=?0'o.&'0{hn";
        for (int i = 0; i < text.length(); i++)
            System.out.print((char)(text.charAt(i) ^ key.charAt(i)));
        System.out.println();
    }
}

Here is challenge #2 for another SC2 beta key. To begin, simply enter the code:

into plain hex code and made it into ascii got

which means go to

"Phase 4

I was born in 1969, but it took four years before I was defined. As I grew old, I was not called upon nearly as much as when I was young. My lucky numbers are 15 and 854. I am on the 7th floor, but there are no more above me.

When you have discovered who I am, kindly direct me to teamliquid.net."
seems like a riddle
which i think hints to the ARPANET ie the 1969 part
but turns out to be telnet
from the wiki
"Telnet was developed in 1969 beginning with RFC 15, extended in RFC 854"
I don't have a telnet client installed on windows 7 so i'll just stop there someone else can try to finsih it althoguh i am curiouse how many more steps there are

people did some stuff on it and got 2 bits of info
A C file crypt.c

- I come to you in the wake of recent events to issue a call to reason.
- Let no human deny the perils of our time
- While we battle one another,
- divided be the petty strife of our common history
- The tide of greater conflict is turning against us.
- Threatening to destroy all that we have accomplished.
- It is time for us as nations and as individuals
- to set aside our long-standing feuds and unite.
- The tides of an unwinnable war are upon us
- and we must seek refuge on higher ground
- lest we be swept away by the flood.
- The Confederacy is no more;
- whatever semblance of unity and protection it once provided is a phantom...a memory.
- With our enemies left unchecked, who will you turn to for protection?
- The devastation wrought by the alien invaders is self-evident.
- We have seen our homes and villages destroyed by the calculated blows of the Protoss.
- We have seen first hand our friends and loved ones consumed by the nightmarish Zerg.
- Unprecedented and unimaginable though they may be, these are the signs of our time.
- The time has come my fellow Terrans to rally to a new banner
- In unity lies strength; already many of the dissident factions have joined us
- Out of the many we shall forge an indivisible whole capitulating only to a single throne.
- And from that throne I shall watch over you.
- From this day forward let no human make war upon any other human,
- Let no Terran agency conspire against this new beginning.
- And let no man consort with alien powers...
- and to all the enemies of humanity seek not to bar our way,
- For we shall win through, no matter the cost."

and w.e this is

0x0030 : 6E 0A : n."

all i can tell from that is that r1ch made an array or string w.e it's C i don't know it with
IFNWOUVYZNALWPFORUCYANAKCIZYQKAPZIWYTOMICUAHQIDFYSNFJKDUAJWKFJAUYZJANK in it then intilized it in void crypt ionno what ^= does not fimilar with that sort of syntax or C for that manner lol
IFNWOUVYZNALWPFORUCYANAKCIZYQKAPZIWYTOMICUAHQIDFYSNFJKDUAJWKFJAUYZJANK is not rot-13 probably is an cypher used in main either way doesn't look like a complete program



im lost looks like code that i don't know about lol but frankly the bottom half doesn't look like c has + in areas where i'd think , would go
var _0x2f70=[...];

function checkStr()
{
msg=document[_0x2f70[2]](_0x2f70[1])[_0x2f70[0]];
if(msg!=_0x2f70[3])
{
alert(_0x2f70[4]);
}
else {window[_0x2f70[5]]=_0x2f70[6]+msg+_0x2f70[7];} ;
};
only thing i can get from 0x0030, 0x2f70 etc is that they are probably memory locations lol but what to do with that ionno

so i pasted
picked start with ETAION and got

so i was like wtf? oh wait.. HD2 BETN KEV almost kinda looks like SC2 beta key..

so did swaps from there to get the full message, not too difficult

so then i was kinda stuck.. but decided to viewsource, ctrl+f'd for "pbqr", saw checkStr, ctrl+f'd for that, saw the array, bada-bing.
then i realize later i could've just pressed quote on the post, lolol.

then got stuck until someone mentioned telnet, played around a bit with it, but aside from ls cd and help didn't get too far until someone mentioned dump. once i saw the ^= operator in the crypt function, it all made sense, and just had to wait several minutes for someone to claim the key ^_^

during the time i was dusting off my old dev c++ lol. totally forgot how to use the damn thing and windows' CLI makes me cringe.. one of the few things i like about *nix is their CLI.

anyway once i finally remembered how to compile and stuff with dev c++, 'twas allright, went to play gunz

actually i remember the first time i fucked up the code, and had my computer emit very loud beeps for the duration of the printout rofl
no idea what that was all about..
