Hello,
I'd like to dump addresses (not keys) from a wallet.dat file I provide on a command line. The wallet is not encrypted. I don't want to install Bitcoin or download the blockchain.
Pywallet has worked for me in the past, but doesn't now.

Code:

./pywallet.py --dumpwallet --datadir=./w --wallet=wallet.dat
'ecdsa' package is not installed, pywallet won't be able to sign/verify messages
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.

I see that jackjack-jj/pywallet is now very, very old - last commit 7 years before.
How to install ecdsa package? The obvious "solutions" from google don't work - pip3 or pip is unrecognized command, and I'm not sure which package from apt to install (but I think this will not solve my problem).
Python version:

Code:

Python 2.7.16 (default, Oct 10 2019, 22:02:15)
[GCC 8.3.0] on linux2

Any suggestions?

The ecdsa message is only a warning, you don't need to install it
The actual error is this:

ERROR:root:Couldn't open wallet.dat/main

And this should not happen if your wallet file is not corrupted, are you sure bitcoin-core can load it?
Or maybe your client is not bitcoin-core but if pywallet worked for you before then I guess it is

I created a somewhat "hacky" fork here: https://github.com/HardCorePawn/pywallet

It suppresses the "keymeta" output spam... and ignores other errors in more modern wallet.dat files (from the top of my head, "bestblock" and "hdchain" cause issues, there may be others). Fairly sure that it would break the "recovery" feature, but it makes --dumpwallet work Tongue

Given the large increase in price of BTC, and the obvious surge of "help I have old wallet.dat, how do I get keys/bitcoins!!" type posts that inevitably accompany a bullrun

That's great, I was hoping someone would do this!
All the help needed is actually part of the reason why I'm back, I was getting more and more emails asking for help

it would be useful to have:
- updated Pywallet that works "properly" with newer wallet.dat files and doesn't just suppress/ignore errors
- Python 3 compatibility would be a bonus, as Python 2 is now completely unsupported

These 2 are a must, plus these:
- clean that crazy source code, there's no reason for it to be 5000 lines long and to be that ugly
- change the --datadir and --wallet arguments
- kill (for now) the web interface and remove the twisted dependency (that would help reducing the code by the way)
- be more explicit about ecdsa being only optional
