Codecracking

[Lizard]

Hi,
can somebody tell me the basics, how to crack a code? I searched at google "cryptography" but i just found sites which told me the history and the definition of cryptography and a code. I wanna know how to start cracking a code, what to look for, what to think about and so on. plz help me.
thx

Heh, for one you need to be able to read the crpyto language [whatever it may be]..
If you want to be lazy then search at www.astalavista.com :/

Hi,
there is no more information given about the code, I have to find the other things at myself. And thats my question : How to start? What to look for? =)
Be my tutor and tell me what to do plz, i wanna just learn it. I dont wanna crack this speacial code, i wanna know the basics.
thx cya

Looking on google it seems that's it's Hex turned into Dec, to get it out you'll have to transform those numbers to Binary then to letters, http://www.tekmom.com/buzzwords/binaryalphabet.html
is the list..

Let's take the decimal number "99" and turn it to binary:
128 64 32 16 8 4 2 1
0
1, 99 - 64 = 35.
1, 35 - 32 = 3.
0
0
1, 3 - 2 = 1.
1, 1-1=0
So 99 in binary would be:
0110011

hi my good friend, yes indeed a lot of encryptions over the net, see if you can try this one, it took me about 5/10 mins (most trying to find what produced the ":" symbol"

http://www.hackthissite.org/missions/basic/6/index.php

make an account its worth it and use that link.


you cannot really teach it, your mind has to be good at non-verbal reasoning, although if i were to teach you one thing

the letter "i" occurs 26 times out of 326 letters above

thats means roughly 7% of the smybols/characters/numbers in your code are "i"s

but w8, there are 26 letters in the alphabet, so 1/26 of the must be i's. no not really, how many z's are there T_T. find and assemble a frequency diagram of the characters in your script of how often the occur, the highest one occuring will be the highest occuring letter of the english alphabet.

this is my own theory
i call it
Lindon's theory of frequency



although "Nooo!!!" if it has symbols in it man

o yer, and don't go crazy like the guy in a beautiful mind

Hi,
@ Maelmord:
sry but i cant use that link cause it require lvl 6 on that page ...
*grml* What do i have to do now?


@ Devil:

I am not sure but i think u'd made a mistake cause 99 = 01100011 ...
one zero more than u wrote. And what is with 210 ? 210 isnt a character in the ascii code.


thx
