Pywallet 2.2: manage your wallet [Update required]

[kjj]

What new features?

By the way, this doesn't work with Python 2.4.2.  I jumped right up to 2.7, so I don't know what the minimum version was.  Among other things, the "A if Condition else B" syntax appears to be pretty new.

[RaTTuS]

I'll help - what do you want testing ....
can test on windows 32bit XP , Vista 64 , linux ubuntu 64bit

What new features?

By the way, this doesn't work with Python 2.4.2.  I jumped right up to 2.7, so I don't know what the minimum version was.  Among other things, the "A if Condition else B" syntax appears to be pretty new.

That's going to be annoying, I didn't want pywallet to only work with one specific version of Python.... It seems to have been included in Python 2.5 though
Anyway, thanks for the feedback, I'll test all the Python versions then and modify the code to work with 2.4


New features are signing/verifying messages (this is the main thing I want to test) and no more crashing when missing dependencies



Signing/verifying messages requires the ecdsa package, but please do not install it yet to test missing dependencies warnings
It is installable with easyinstall(not sure for windows and osx):
 Linux Debian-based:
  apt-get install python-setuptools
  sudo easy_install ecdsa


 Windows:
  32bit http://pypi.python.org/pypi/setuptools#downloads to install setuptools
  64bit http://pypi.python.org/pypi/setuptools#windows to download, then run ez_setup.py
 
  Go to C:\Python27\Scripts
  Run easy_install.exe ecdsa

 OSX:
  http://pypi.python.org/pypi/setuptools#cygwin-mac-os-x-linux-other
  or found that too: http://stephenhucker.com/2008/04/08/python-easy-install-on-os-x-105-leopard/



I will post here when I push the new release in github



Also it seems that I forgot to post here that exporting/importing all the tx's to/from a json file have been implemented, see here for instructions

[jackjack]

I just pushed the new release to Github

So:

• Do not install ecdsa python package yet
• Download the new pywallet
• Run it, and check it says "'ecdsa' package is not installed, pywallet won't be able to sign/verify messages" in the console
• Close pywallet, install ecdsa package, see previous post
• Run pywallet again, check that "get info" section became "get info or sign/verify a message" with new input forms: Message, Signature, Pubkey
• To sign a message with a private key, fill Message and Key
• To verify a signature, fill Message, Signature and Pubkey

Some testing:

Please share your signed messages so that we can all verify each others ones



Todo:

Not having much luck signing.  I tried to verify my own message, and it fails.  I clicked a few more times, and I get a different signature each time.

Not good, I can't verify your sigs neither
At least does it verify your own sigs?

Btw, different sig for same msg/key is normal

[samr7]

This new signature feature is pretty darn cool.  Looking forward to seeing the verification work.

One of these days, pywallet will become the new PGP!

[ctoon6]

so if i want to use the new version of pywallet, do i need to run it without ecdsa, or is it just to test to make sure it works without crashing?

[kjj]

Still nothing.

I tried it with a different key.  By the way, if you use --web, it ignores --wallet= on the command line.  It'd be nice if that carried over.

I went used Dump Your Wallet and copied out one of the "sec" values, scroll down to the info/sign/verify section, paste in the key, Get Info.  Results:

I changed the message to "test" just to make sure the question mark wasn messing up the URL encoding, and it still failed verification.

[jackjack]

so if i want to use the new version of pywallet, do i need to run it without ecdsa, or is it just to test to make sure it works without crashing?

I just pushed the fix
Now if you run it, it should write that ecdsa is not present, and run normally except that you won't be able to sign/verify

I hope it's ok because here it works

Good idea for the wallet flag, will do it as soon as I resolve that

[kjj]

That one works.  The "Thank you guys!" one does not.

[jackjack]

What a dumb!
I was signing my test string instead of the msg form
Try your signatures as if the message were "coucou", it will work...

New release pushed, it will surely work better

Yes sorry I should have said that before

Three cases:
1. You just want some info, then just fill Key as usual
2. You want to sign, then fill Key and Msg to sign Msg with Key
3. You want to verify, then fill Msg, Sig and Pubkey to verify that Sig is a signature of Msg by Pubkey

Works.

key = bitcoin private key, can be found by dumping the wallet.
message = message to sign or verify
signature = signature of message to verify
publickey = public key of message to verify
Version = used to create the address format.  Should be 0 currently, but can be different in the future, or for testnet.

To get key info, you only need to fill in the Key: field.
To sign a message, you need to fill in Key: and Message:.
To verify a signature, you need to fill in Message:, Signature: and Publickey:.

Yeah, the silly forum software munges lines by adding spaces or newlines to long strings.
