I never made any backups, unfortunately.. To the above person saying "that's what you get", I obviously didn't play a prank on myself -.- this is clearly doable, simply not by me. But thank you for your pseudo-concern (in other words, thanks for nothing). The reason I was asking for a bruteforce method, specifically a GPU intensive one, is that I have access to enough GPU, or I'm okay waiting a month. It's not really a viable solution, but it's the only one that will work 100%
Whoa, take it easy. What I posted above is really all there is you can do. How many btc did you have?
The post was directed at the other person "gweedo", I appreciated your post, thank you. I had about 5 at the time, which is a fair amount of money but nothing to buy a super computer for cracking over.
Don't blame me for your stupidity.
I'm not responsible for the ignorance of others. That includes you. Nice to know this is a community with inhabitants that have over 4000 posts of pure unintelligent spam. Do go waste your life elsewhere, as I'm sure you have other threads to post unintelligent, incorrect responses to (Tells someone they are stupid after claiming that you can't bruteforce a wallet. Makes sense).
If you know nothing about the password, even a dictionary attack might not be enough - unless the password is weak, which might be the case since it was supposed to be a "prank".
Honestly, if this "prankster" has a minimum of honesty, you should push him/her every fucking day to pay you back. This is theft/vandalism, not a prank.
Once s/he pays you, you give him/her the encrypted file, and it's up to the person to decrypt it, not you.
That assuming the prankster has a minimum decency, of course.
I've made sure they were aware that it wasn't funny. Unfortunately, even if they would pay it back, they aren't able to.
Bitcoin is installed on ubuntu, I will look at that thread though, thanks.
