Can we get a hint?!? Lol, I don't even know where to start.

It is not a standard cipher at all & it is found in the preliminary text when someone starts learning computing in his/her early days. :)

I will try to find time to give this a try. I don't know why but ciphers really interest me.

Computing in what though? I learned many languages back when I was going through Windows NT programming even in C. There's a whole system language embedded there. I was unsure about this, but when I have a few hours maybe it'll rack my brain for a bit when I test it lol. I'll see what I can do, no guarantees. I've come across some fairly hard challenges, but i've passed a few of them.

RE: Challenge #19 - CSAW CTF Crypto #1
WooHoo, Another one bites the dust. :)

The numbers are ascii code for alphabet characters. In a text editor, hold down the "Alt key" while typing the numbers above (87, 101, 108, 99, 111, 109, 101). Using excel "=CHAR(87)" function will give you "W".

The message is "Welcome to the 2011 NYU Poly CSAW CTF event. We have planned many challenges for you and we hope you have fun solving them all. The key for this challenge is cryptography."

RE: Challenge #19 - CSAW CTF Crypto #1
Lol, man. I didn't think it'd be that simple. I was making it WAY harder than it was.

[spoiler=Nice work clifford]Ah!! I was going about this the wrong way. I didn't know it was going to be that easy. My initial thought was that they were the Char codes but didn't think that would constitute as a 'cipher'. Anyways good job clifford! (now that you've solved it, those Char(32)'s do look mighty suspicious. :D )[/spoiler]

RE: Challenge #19 - CSAW CTF Crypto #1
If it was any harder I might have gotten it lol, I was taking KoBE's approach and thinking that it was something in a unique cipher encryption, making it seem way harder than it was. I didn't look for the unexpected

Nice work clifford, I didn't manage to get it but good job :)
