Yes, way slower, but not impossible.
It is indeed a 100% possibility, maybe in some countless millions of years.
Why don't you issue a direct challenge to hackers? It is the quickest way to find out!
I would like Mike B to prove me wrong since he said .rar file can be decrypted/forced.
Mike is a good guy, but others might take you up on the challenge.
First, I said "depending on the encryption". So that obviously matters.
Second, if the encryption is weak, it can be brute forced. There used to be a weakness whereby you could do some file modifications and glean the password. It "hopefully" has been fixed. I love the guys thinking they know stuff by using bruteforce as a standard of cracking. Anyone with half a brain would NOT attempt that and would look for other weaknesses.
Point being is...there are a number of ways information can be gleaned. There are also dumb ass people would would just zip the file instead of rar it with a strong encryption.
Why complicate it when you can use a hardware wallet with a PIN that does the encryption for you? And where are your balls? You could have commented right on the video...
About 5 years ago,a few guys I worked with needed excel docs that were .rar'd. We used a workaround to glen the key. The guy who did it was keeping stuff under his hat and making life difficult thinking he'd gain job security.
