Shuffle-Cipher-Desktop

Purpose

A desktop application to cipher your plain text into garbage ASCII strings!
This desktop java GUI application helps you mantain privacy by ciphering simple text and turning it unreadable via a simple Cipher algorithm cooked up for fun.

The application further allows you to password-protect ciphered text, to prevent it from being deciphered by anyone with access to the application and your text.
Note: This algorithm is not industry standard encryption, it is simply a 3-layer cipher algorithm designed to make text human-unreadable-
The ciphered text is vulnerable to reverse-engineering, and should not be considered a guarantor of 100% privacy

The application GUI is built in AWT/SWING(JAVA 8).

How it Works:

What exactly does this program do, you might ask? Simple, really- it reads the ASCII values of each character in the string inputted by the user and just, well- plays around with the values. Think about it for a second- the ASCII value for the space character is 32, right? Now boost that value up by a random number between 8000 to 22000, say 9000- the said ASCII value now becomes 32+9000=9032 i.e '⍈'.

Now, what if we took in a string and boosted each character in the string by 9000?

Sample String: "MAD SUS!"

Boosted String:"⍵⍩⍬⍈⍻⍽⍻⍉"

Boost Value/key: 9000

Now, simply subtracting 9000 from each character's ASCII value in the boosted string, we get the original string. Of course, such an encryption standard is trivially easy to break/reverse engineer, but it gets my point of playing around with ascii values to render text unreadable across.

Encryption routine in it's simplest form:

public static String encrypt(String s,int boost)
{

    String ss="";

    for(int k=0;k<s.length();++k)

    {

        char ch=s.charAt(k);

        ch+=boost;

        ss+=ch;

    }

    System.out.println(ss);

    return ss;

}

Of course, we can spice things up a bit- instead of adding up values to each character in the string, we can subtract a random value(say, between 20 and 40) from alternate characters in the string.

Now, we have a string with characters at odd positions boosted by say, 9000 and characters at even positions subtracted by say, 30.

Input String: "MAD SUS!"

Boost value: 9000

Decrement value: 30

Encrypted String:"/⍩&⍈5⍽5⍉"

To reverse the conversion, we simply need the boost value and decrement value, which will be used as keys- characters at even positions will be boosted by the decrement value and characters at odd positions will be decremented by the boost value.

Of course, to increase the complexity a bit, other conversions can be factored in, such as breaking the string into two parts at a random position and reversing one part(the first half), then adding both strings back together, increasing the complexity of reverse engineering the algorithm and simultaneously adding a third key to the algorithm.

Final Encryption Routine:

public static String encrypt(String s,int boost,byte decrement,int pos)

{

    String ss="";

    for(int k=0;k<s.length();++k)

    {

        char ch=s.charAt(k);

        if(k%2!=0)

        ch+=boost;

        else

        ch-=decrement;

        ss+=ch;

    }

    //Split the string into 2 parts

    String a1=ss.substring(0,pos);

    String a2=ss.substring(pos);

    //reverse the first half

    a1=new StringBuffer(a1).reverse().toString();

    ss=a1+a2;

    System.out.println(ss);

    return ss;

}

Final Decryption Routine:

public static String decrypt(String s,int boost,byte decrement,int pos)

{

    String ss="";

    String a1=s.substring(0,pos);

    String a2=s.substring(pos);

    //reverse the first half to bring it back to its original state

    a1=new StringBuffer(a1).reverse().toString();

    s=a1+a2;

    for(int k=0;k<s.length();++k)

    {

        char ch=s.charAt(k);

        if(k%2!=0)

        ch-=boost;

        else

        ch+=decrement;

        ss+=ch;

    }

    System.out.println(ss);

    return ss;

}

Input Text: "That's mad sus!"

Boost value:10000

Decrement value:40

position key: 3

encrypted text: 9❸,➄ ➃￸❽9❴￸➃M➃

decrypted text: That's mad sus!
