I have a question out of pure interest, I'm a fan of police documentaries like K11, In the Name of Justice, Tatort etc.
There it is always like that when the police find a laptop and the password is protected, they say "Yes, our forensics will do that with the left." Or recently in a K11 episode that I saw the police picked up a man who was arrested and picked up a phone where data was protected with a password. The young man did not want to say the password and 5 minutes later they had cracked the "password" - the police.
Now I wonder is it really as simple as it is shown in the film? Personally, I have passwords with a character length of at least 20 characters to 25 characters. With several upper and lower case letters, numbers and at least one special character. There are various password checkers on the Internet, now I'm not that stupid and just type in exactly what I do, for example. Use for online banking. If I enter my current password in a completely changed version, an attack would take 65 trillion years. So I would say for sure.
But now an example. I'm creating a RAR archive which contains a text file with a strict secret text. And I encrypt this RAR archive so that names and data are protected. And that password would now take 65 trillion years to crack using brutal force or dictionary attack.
If I now open this archive with Notepad ++ I can see that it is a .rar archive (but I can also see the file extension) but I can't recognize the file names or contents of the file from the outside. The same archive but without a password with the same content can be recognized in the editor, both the name of the text file and the text in the text file. In this case the archive was encrypted using AES-256 bit encryption.
Does anyone know their way around or something? In reality, is it really that quick and possibly easy to crack the example described above or to get the data without having the password? Or is that more of a movie thing?
Mfg Have a nice Good Friday!
Yes, since most of them have no idea and use free software for it, it is easy to crack…
Programs created by professionals are not cracked…
Ah interesting. In the case I described, the archive was created with the paid software WinRAR.
It is not that easy. Professional encryption programs are safe. Brute force can crack that too, but it can take time.
