You can use BTCrecover or whatever techniques you have to find the password.
This is a technical discussion so I belive am in the right place.

i will give 1 Bitcoin to anyone who can decrypt the attached file .

this's my bitcon address : 1L8SqDEvaA3WnDinobai21ZbnyC79XuJGn
you can take a look at it

please copy the hash in text file and try :

Everything you are attempting here is plain wrong.

Forget mining BTC with a PC, those days are over and have been for a decade.

If you want to get into solo mining of bitcoin then go and buy an entry level ASIC miner, there's litterally no other entry point for mining bitcoin these days.

There's plenty of devices to choose from Gekko Science Compac A1, Compac F etc or one of the many BitAxe devices.

Mining solo with anything less than 1TH/s is a waste of time and even at that level you'll be rolling the dice with really long odds.

Do a bit more research before you commit to such ventures.

If all you're interested in doing is burning money then sure waste your time setting up a PC with a high end GPU and maybe achieve 1-2 GH/s if you're lucky.

PC's might be suitable for Altcoin mining but forget it for BTC.

Using just a PC or even PC w/GPU is beyond useless and an absolute waste of power.... ref https://bitcointalk.org/index.php?topic=2415854.0 point-3
When running on the same PC at the same time that you would be attempting to mine BTC with - that does not even deserve an answer.... For either algo the PC MUST be doing just that 1 thing or you are just jerking off in a fantasy.

Bitcoin Core v0.21.1  has no problem for solo miner. mining cmd: getblocktemplate and submitblock got no changed and work well.

cgminer 4.11.1 need to fix it to work on gbt_solo mode. The cgminer got three work modes: has_stratum, has_gbt and gbt_solo.
I found it is very hard to run c code when segment faults often pump out. You have to work out yourself as solo users.

Here's how I am doing it. 

BFGMiner is able to mine against 0.21.0 but CGMiner is not.  However, BFGMiner is not compatible with Newpac sticks (not 2pac or compac those work).

So I run bfgminer as a proxy only, then connect my cgminer to bfgminer.
