Chipertext part1

CHIPERTEXT encryption method is a row of the characters that have been determined. Here I take a simple example for implementation. Some software is protected by a serial number to use this method for the combination. Software that is distributed shareware, trialware and Evaluation version uses a combination of methods to protect a serial number that made the software. Shareware version and the version EValution may only use Nag Screen, or there may be a function of the software, which can not be used, if not in the register with the right serial number.

There are several methods that use serial number:

1. Not user name, usually a serial number can be used by all users. The method is usually used to share a number with the number and specific results for the remainder used.
Example: Suppose a serial number with the combination mode
"Figures from 1000001 to 3000001 and 87184 mode.
"If the rest of the results for 0 printed the results of The member's share.
"The member's share of that remaining results are used to protect their software.
Example applications that use this method:
ACDSee (a combination of a time xxxxx-xxxxx-xxxxx-xxxxx).

2. Noting the User name, serial number will be different for each user name is different. This method uses a combination of results from the encryption user name used. There are various methods to encrypt the user name, the results of encryption that is a serial number valid for one user name is.

Well, let's start with membahasnya:
There are some things that need to be considered include:
* Character Input.
inputan is a character that in the future so that the encryption code encryption.
* The character is a row of keys that will be movable.
inputan from above the movable character based on the row.
* Key Penggeser, we take a serial number from the volume of drive C:.
the value of the volume serial number is usually the C drive hexadesimal that need to be changed to an ascii number.
* Output of characters.
results from the combination of a code serial number.

We start with the example of the application:
* Inputan characters such as: BALI HACK
* We take the example of a row of keys movable as follows:
BALIHACK a `~ bD! C @ d E $ #% f e ^ F & g * h (G) i-hh = k + l \ M | m (n) N; o: p'O" qs.t? Q / uvRwxSyzT01U23V45W67X89Y0Z
* Key penggesernya The serial number is drive C: for instance 2941-13F8
then we translate the code to an ascii 294113F8 = 5057524949517056.
* Let's start manggeser:
B movable 6 characters into a
A movable characters into a 9
A movable characters into 7 K
I movable 0 characters into a
H 9 movable characters into `
A movable 5 characters I become
C 7 movable characters into a
K 6 characters become movable @
So in encryption BALIHACK become AAKa It `@, tersebutlah code is a serial number that is generated. This method is a simple method, you can develop your own. Suppose you create a table of key or use your serial port I / O as the value penggeser (of course you must understand the binary number) and other so forth.
