Just writing some code

Hey there!

I don't know if this is the right place to post/ask. Let me know if it isn't, but here we go:

This is not the right place to post. Make a new thread. It belongs in the Alternative Clients section of Development and Technical Discussion.

I downloaded Bither on my iPhone, saved the seed code and the password on my PC - then it died and I wasn't able to save any data (yes this is stupid and I have no one else to blame but myself, so we can skip that part

). Now password is lost and I have bitcoins stuck in my Bither account. I have still access to the wallett but obviously can't send the money out because I don't have password. I do have an idea what the password might be - is it somehow possible to use brute force on my phone?

If someone can help me figure this out, I'll give them 1 BTC.

Thanks for the help!

First try doing hard drive recovery on your PC. If your hard drive did not fail, it should still be possible to recover your data.

Bither obviously has the wallet file stored somewhere. It should be possible to brute force the wallet to recover your password. Since you have an idea of what the password is, it isn't entirely impossible to brute force it.

I will be locking this thread because it is old, way OT now, and easily hijacked.

I would try first to recover the saved seed and password from the "dead" computer, because probably the hard drive is still usable/recoverable.

I can try my best, I already promised to test GTX1070, but I did not have a time. Please let me know if the help is still needed.

Ok, so this thread gets a blast to the past.

Running Ubuntu 16.04, Bitcoin Core, encrypted wallet - I know the passphrase, I must have just fat fingered it twice in exactly the same way, which I have been unable to duplicate.

Followed Revalin's instructions from pages 2-4, however I cannot get the brute.rb to copy to the usr/bin folder, which is where I THINK it goes. That's where the bitcoin-qt app is and Revalin indicated the brute.rb file needed to be where the Bitcoin app was located.

No matter what variation of "sudo su" [password] "sudo cp ~/home/username/Bitcoin ~/usr/bin I try, I get, "cannot stat 'blah/blah/blah (path): No such file or directory

I cannot drag the file the the usr/bin folder because of the permission issue (goddam linux needs an override for that).

Help would be truly appreciated.

I will recommend you to use https://github.com/gurnec/btcrecover, read the entire tutorial and I'm pretty sure that will work.

Cheers.

I can test with GTX1070.
This one mentions Experimental GPU acceleration,
but I'd rather have binaries and steps 1) 2) 3) what to do.

OHHHH that would be just awesome. there is all the softwares you need to run btcrecover : https://github.com/gurnec/btcrecover/blob/master/docs/INSTALL.md and if you look at the end there are those needed to activate the gpu.

Will it break the 10kp/s ?

Any results for latest Nvidia GPUs ?

Very interested too. Would love to see what a amd 480x can do vs a 1070 or 1060. The Amd has more processing unites, and the ram are the same... however it seems that the nvidias hash more. If anyone has the time to do a quick test it would be greatly appreciated.

You need to navigate to the directory first.

The folder you're currently in is shown before the cursor, i.e.
C:\Users\John> _

If you type "cd bitcoins", your current directory would be set to "C:\Users\John\bitcoins". To go back up a directory, type "cd ..", i.e. to "C:\Users\".

You need to set your current directory to the folder where feathercoin-qt.exe is located. If it helps, on my system that folder is C:\Program Files (x86)\Feathercoin.

SP4RK7, I've tested it and I get a similar error. Currently trying to figure out what I've done wrong, will post in here soon.

Little update: do you think it's better a 1060 or a 480x for btcrecover? the 1070 is a little bit too expansive. Why would one perform better?

I'm afraid I don't know enough about OpenCL to say which architecture is better... I'll give you what little I do have though.

These are P/s rates from a Bitcoin Classic/XT/Core wallet with an iteration count of 67908.

1x 560 Ti: 1070 P/s
2x 560 Ti: 2110 P/s
1x R9 390: 4470 P/s

(the test numbers for other wallet types are here)

It's an apples-to-oranges comparison, but I'd guess that it points to AMD architecture at being better for this... but it's just a wild guess.

Quote from: ?? on ??

does the size of the ram on the card has much influence? thanks in advance...

For Classic/XT/Core, VRAM makes practically no difference (you just need 64 x --global-ws bytes). For Armory, it makes a big difference.

Edit: I just noticed an old thread by you.... if you have any specific questions, feel free to ask, but in the mean time:

By adding the "--delimiter *" option, "*" is now used as the delimiter between tokens, instead of spaces. This means you can use:

%[ _] - a single space or underscore (note the space before the _, it may be hard to see)
%0,1[ _] - 0 - 1 single spaces or underscores, e.g. a single space or underscore or nothing at all

Hope it helps.

I need a help guys, I forgot password of my wallet (maybe part of it I know, some words for instance, but not sure about the order).

I tried with Revelion scripts but when I run brute script it says "incorrect RPC user/pass". I am running latest bitcoin core, and Revelion scripts are a bit old, hence there might be some incompatibilities. Anyhow, I manually made bitcoin.conf file and set the same user ans pass as in script, but script still won't run.

Do you have any other solution that works with latest bitcoin core?

I also tried this script https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#windows--bitcoin-core-multibit-classic-or-electrum , script itself runs but no password match (I tried with all "possible" words that could be within the password but with no result), hence I doubt it actually works.

I want to help you, I have some equipment and necessary programs.

btchris, is there any btcrecover official thread yet, isn't?

I configured easily the GPU accelerated recovery over Windows 7 64bit. Nowadays I used as recommended all 32bit stuff, I will try the 64bit and Linux configuration later.

The setup is: Asrock H81 Pro BTC, Intel G3220, 2x 4GB RAM, 3x MSI R9 280X Twin Frozr with stock clocks.

Best results were with all combinations of --global-ws 32768, 65536 and --local-ws 64, 128, 256 averaging 11.25 kP/s. Pretty fast stuff.

Anyone have some other benchmarks to compare?

Did you test it against a bitcoin core wallet?

I got 1.65 kP/s with a single GeForce GTX 970 using --global-ws 65536 and --local-ws 1024, but somehow the password is not found, see screenshot below.

Yes, it was tested with bitcoin core.

Also getting 13-13.5 kP/s now with this configuration: Gigabyte Z87X-UD3H, Intel G3250, 4GB RAM 1600, SSD Kingston V300, 5x HD7950 with stock clocks and USB 3.0 risers. Which renders 2600-2700 P/s per HD7950.

Will be any improvement in performance by connecting the GPUs directly to the motherboard ? I don´t know if the bus is important for btcrecover.

Delusional crypto obsessionist

Might been said before. Didn't bother to read the complete thread TL;DR
I've been looking into this tool in the past https://github.com/gurnec/btcrecover
Might be helpful.

I've got a friend with the same problem, but the wallet only contains 0.22BTC
We did not bother too much, yet.

edit: ok ok, at least I could have read the last post before me :-)
I see you've already been advised about btcrecover

btcrecover works, I can confirm it; it's the one I use and it certainly works. The most probably thing, is that you are not putting enough words on the password, or not the right ones. Other possibility is that your wallet.dat file is corrupted.

I can help you, just check my signature and if you agree, contact me.

Hope you can get your coins back. Cheers.
