Hello,

Installed pywallet on Mac OS 10.13.2 with all dependencies trying to dumpwallet through web interface getting same "error parsing wallet.dat" on my terminal window.

wallet has a password on it, is there anywhere on the web app I have to first enter the password to unlock the .dat before dumping?

Thank you

Hi, if you are still here and need to try and recover your wallet.dat, I would like to offer some help.

I've just had to do it for Bitcoin Core on my server

Message me if you would like a quick chat, and what your expectations are in terms of recovery time, and the information you have to help recover (guesses of passwords/phrases, list of passwords you have used in the past which you may have put on your wallet.dat).

I believe first you may need to run a fixup script before attempting to crack the wallet and recover the password. If you're interested please get in touch.

Just started getting same error. all dependencies installed using pip (new install of windows 10 this time)

Python-2.7.11

Code:

line 2111, in parse_wallet
    d.update(parse_BlockLocator(vds))
TypeError: 'NoneType' object is not iterable
ERROR parsing wallet.dat, type bestblock

parse_BlockLocator function is

Code:

def parse_BlockLocator(vds):
	d = { 'hashes' : [] }
	nHashes = vds.read_compact_size()
	for i in xrange(nHashes):
		d['hashes'].append(vds.read_bytes(32))
		return d

not great with python so any help with be appreciated.

I found the problem. Tongue

Please tell me how you solved this problem.

I think this might be something to do with new blocks in 0.12.x, Maybe pywallet needs updating or such.

This

I don't know the format of the new blocks, I'll try to find specs and potential fix but I can't promise it will happen soon

Any news on this topic?

my old static folder BitcoinCore0.10 has not been updated since and that works fine.

I'm using pywallet (https://github.com/jackjack-jj/pywallet) to dump my wallet information but it doesn't seem to be working. Instead it returns the following error:

Code:

...

I'm running OSX 10.11.4 (El Capitan) and followed the instructions to get pywallet running on my machine, but the script doesn't seem to be working. Any advice?
