100.cpp

The following C++ code generates combinations of characters from different character sets based on the command-line arguments provided. It is designed for hackers and password cracking purposes.

The solution is to use recursion on the given character array. The idea is to pass all possible lengths and an empty string initially to a helper function. In the helper function we keep appending all the characters one by one to the current string and recur to fill the remaining string till the desired length is reached. It can be better visualized using the below recursion tree:

     (a, b)
      /   \
     a     b
    / \   / \
   aa ab ba bb

Algorithm

1. Initialize an empty list passwords.
2. For i in range(1, length+1): a. Generate all possible combinations of length i of the characters in arr using the itertools.product() method. b. Convert each combination to a string using the join() method. c. Add these strings to the passwords list using the extend() method.
3. Return the passwords list.

Usage

The program accepts the following command-line arguments:

• -l or --lowercase to include lowercase letters
• -u or --uppercase to include uppercase letters
• -n or --numbers to include numbers
• -s or --special to include special characters
• -j or --japanese to include Japanese characters
• -r or --russian to include Russian characters
• -c or --chinese to include Chinese characters
• -a or --arabic to include Arabic characters
• -k or --korean to include Korean characters
• -h or --hindi to include Hindi characters

You can mix and match these options to create the desired character set for generating the combinations.

To execute the program, compile and run the code in a C++ compiler with the desired command-line arguments.

Example

Here's an example command to run the program with lowercase letters and numbers:

g++ -o 100 100.cpp  # Compile the program
./100 -l -u -n -s   # Use the program

This will generate combinations using lowercase letters and numbers.

Execution Time The program also measures the execution time and displays it at the end.

Note: This program is designed for hackers and password cracking purposes. Please ensure you have proper authorization and legal rights before using it.

Feel free to modify the code or adjust the command-line arguments to suit your requirements.
