Awesome, thank you so much! I owe you one.

It's fairly easy to pull this info from a full node. The full node I run is in a VM with 4GB RAM, and the method I'm familiar with (https://github.com/znort987/blockparser) requires a machine with closer to 128GB.

No worries, it's important to be careful. If you happen to be in Australia, I would be more than happy to meet in person. I'm in Melbourne.

Otherwise, I wish you the best of luck! Unfortunately, I do not believe you will not be able to recover just a single character of the password (without recovering the full password). That's possible in some situations where the clear-text password is stored in a database, but I'm not aware of any method to do that with this type of encrypted password. That would sort of defeat the purpose of strong encryption.

However, it is interesting that you say a single character might help you remember the password. That leads me to believe it is something based on a real word or sequence of words. If that is the case, you might be better off working to collect robust wordlists and transform rules than simply brute-forcing ever possible character combination. This may give you a better chance of success with limited time and compute resources.

You can search Google for password wordlists and rules, and use tools like hashcat for a different approach. I plan to write a full tutorial on this within the next two months, and I would be happy to share it when it's ready.

Good luck!

Hi mate,

Very sorry to hear about your lost coins.

You're getting some great advice in this thread, and it seems like some smart folks are already helping out.

I'd also be willing to give this a shot. I work in security and cracking passwords is part of my job. I've developed my own tricks, and perhaps one of them will work where the others have not.

I'm new on here, but you can see some of my posts on reddit at http://reddit.com/u/initstring.

I'd only need a hash of your wallet file to work on the password, not the wallet itself. I would ask for a fee if I could recover it.

Let me know if you're interested. If not, keep working hard and following the good advice on this forum.

Either way, best of luck and I hope you get your coins back!

Thank you very much! I'll keep an eye on the thread. Much appreciated!

Hi @btctousd81,

Is there still a working link to download this? I would love a copy and my current full node isn't powerful enough to generate in a reasonable time.

Either way, thanks!

Thanks! For anyone else reading, I noticed that bitcoin-cli worked properly when bitcoind was invoked via the command line, but not when running the GUI.

Adding "server=1" to bitcoin.conf fixed this issue.
