Brute Forcing RAR file using several PC Paying in Bitcoin

[Calli]

Lets say hypothetically I have a rar file, version 3 to be precise which starts with $RAR3$*0*
tip
We can extract the rar hash using rar2john

Now lets just assume that the password is 42 character long (we don't no for sure how long the password is in this case) and it includes random numbers, letters and symbols
which means it will take this amount of time to crack it

Keyspace = Math.Pow(62, 42) = 1.9074403212938070052188251342723e+75

Now what if we use 5,000 to 10,0000 PC to crack this hash. Will it be possible? I believe YES because nothing is impossible.
How long will it take for a super computer to find this hash?

Now lets get to the building part

Requirement For Brute Forcing
1) Need a executable file which will run on windows machine
2) This windows machine will communicate with the server
3) All the PC will brute force and store the last password until it's found
4) If some PC goes offline and comes back online it will first communicate with the server and continue with the next brute forcing step so it doesn't have to start from the beginning all over again
5) If I am missing something that can be added.


Remember we won't be using wordlist but instead we will be brute forcing and the said rar is version 3 which starts with $RAR3$*0*
