Hi , im learning how to hack atm , after that im gonna learn how to program , but i realised that a important part in hacking is decrypting , encripting , coding , etc.
Im really new to this things , any1 got any guidea bout encripting , coding , etc and a any explanation about ASCII table? because i dont understand anything about that :S

Here's a simple cipher method called the Ceasar Cipher (click the name for the link). It's basically when you move the letters of the alphabet over a few spaces, for example:

A = C
B = D
C = E
...
...
X = Z
Y = A
Z = B

That in mind, try to figure out this simple message (Hint, it's a +4 shift and all letters are captial):

M PSZI LXW

It shouldn't be too hard, since you know the encryption used. Now some might argue that is not encryption, since it is so weak, but it still is in the simplest form, encryption.

Once you get the idea, you will be able to understand other forms of encryption that are much more advanced and efficient.
Assume that everything I say is or could be a lie.

Am i correct or wrong?
btw in my encription in basics i got simbols , how to decrypt them?

You're on the right lines, but not shifting it enough. Hint: It's a phrase.

Symbols are just like any other character: They can be represented in the ASCII table. You just need to notice patterns in the encryption, and reverse it.

omg thats really hard for me >.< xD
btw i dont know how to ''read'' the ASCII table , i just see a couple of numbers and characters and nothing more .. btw how can the symbols be like any other character ?like a=c c=e but ;=......... idk :S

Every character you see on the screen has an ASCII code to it. A computerized version would add or subtract from that value to get the encrypted version. Then do a mathematical operation to undo the encryption. You just need to know the number that was added/subtracted.

Ok first and simple: ROT13
There are 26 letters(All capital):
Code: Select all
ABCDEFGHIJKLMNOPQRSTUVWXYS

Lets assign a value to each letter
Code: Select all
A:1
B:2
C:3
D:4
E:5
F:6
G:7
H:8
I:9
J:10
K:11
L:12
M:13
N:14
O:15
P:16
Q:17
R:18
S:19
T:20
U:21
V:22
W:23
X:24
Y:25
S:26

Not ROT13 is basically, shift 13 in any direction.
So by instance. If I type Tbbq Wbo in rot13; what does the message says?
