I know you mean 'ASCII'. What do you mean by decrypting ASCII?

Download the Handbook of Applied Cryptography and read it. Not as easy as just "decrypting ACII". Depends on a lot of factors.

So what's the key? You can't go around decrypting stuff without a key.

Just so you know how encryption works.

Basic example.
Each character & special character known to the computer has an ascii code Eg.

A = 065 and B 066 and C = 067
a = 097 and b 098 ect.....

So when people encrypt data they convert from character to ascii
So lets say the data you want to encrypt is ABC 065, 066 ,067
It is then a numerical value so now they can use their own Mad Formula
called an algorithm 65 + 66 + 67 = 198 * 23423 /3 * 235 to the power of what ever the pc can handle.
= 573475783458458458 big number then that gets converted back to Character.

and that = "FDHD%&()HFGH/UYTRTThe" above is just a simple example more advanced techniques are used

So not unless you know the algorytm usesd you wont be able to hack it or crack it what ever the correct word may be

Uhm, yeah...what SBSP said. Maybe you should post the problem in its original context?

What is your keyword ?? (For decrypting I mean)
THEN I can help you
Also maybe post the whole context of the question ie. Where did this particular encrypted text originate from ?? {As Y0gurt stated}

not forgetting that raw encrypted data needs to be massaged before transmission can occur, which further defaces the data. Also, as the output is just 8 bytes, i can gaurantee that the cipher used is tiny, (the word miniscule springs to mind)

this thread made me laugh... just a little bit... :lol:

Soo we might be able to crack the encryption by using stupid keywords like:
granny, mom, modem, nokia or guttman ?

Ha!!! got it, but you got to work for it.

Use an ASCII table
http://www.neurophys.wisc.edu/comp/docs/ascii.html

convert the following to numbers characters.
110,048,048,066

Code: Select all

         107      153    06B   01101011        k
         108      154    06C   01101100        l
         109      155    06D   01101101        m
         110      156    06E   01101110        n
         111      157    06F   01101111        o 
         048      060    030   00110000        0
         049      061    031   00110001        1
         050      062    032   00110010        2
         051      063    033   00110011        3
         052      064    034   00110100        4
         065      101    041   01000001        A
         066      102    042   01000010        B
         067      103    043   01000011        C

It's like this:

Lets take an example like "abc" (ignoring the quotes)

encrypting it would give me "ace" (ignoring the quotes)

(For the first one I'd add +0 on the ASCII table (going positive), for the second +1, the third +2, etc.)

But when decrypting you go backwards on the table (going negative). However when I decrypt the sequence and try it, it isn't correct, when I try to re-encrypt the decrypt password it dosen't come up as the orginal sequence that I used.. This is why I need help :cry:
