Part 3: Hashcat Free Excel Password Recovery (Command Line)
Hashcat is top-rated password recovery software designed to break the most complex passwords. The versatility of this software resides on the sophisticated algorithms that allows the program to run various cracking engines. The mechanics behind Hashcat are closely associated with the use of hash keys such as Whirpool, MD5, RipeMD, SHA, etc. All these protocols are designed as directional function keys, a mathematical operation that is very easy to come up with, but that it has proven to be nearly impossible to reverse engineer.
The program turns the readable data gathered by it into random strings of garble, most of them with a predetermined length size. It's important to notice that Hashes do not allow the decryption of data using keys. The means to break the encoding used by Hashcat are pre-programmed dictionaries, rainbow tables, and brute-force approach. Since the software doesn't require installation you can use it in one of two possible ways:
1st Method: Start the program, open the command window by pressings Win+x, and select 'Windows PowerShell' then drag-and-drop the executable file on the command window that pop-ups. You will likely find an executable file named hashcat64.exe or hashcat32.exe according to the type of system you are using.
2nd Method: Again, run Hashcat and open the command window by pressings Win+x, and select 'Windows PowerShell.' This time you will use a command line to change the working directory in place to the one where the executable Hashcat file is located. After you are done start the program again. Now you only need to type the name of the executable file by indicating the current folder where it is. That folder will be easily identifiable because it contains a period in the title (.) After that, you will have to place backslash on it (/) and run the new executable using Hashcat throughout the instruction menu, under options.
Closing Words:
Save or write the password if you were going to set up a protection for Excel file. I have seen many people coming across this issue in my office. Though it is kind of easy to recover the password, there is absolutely no need to waste time on it. It only takes seconds to unlock the workbook if you kept a copy of password.
