Multi-sig paper wallet generator..

[Inca]

Day off so I made a paper wallet generator which can export jpg or pdf files. It either generates fresh random private keys or can take user supplied keys for any reasonable m-of-n combination.

Example output here for a 2 of 3 multi signature address:

And here is a 3 of 12 example wallet..

If anyone wants the python code just msg me..

well done.

may I ask why not setting up a github/bitbucket repo and put there the stuff you intend to share, using an open-source licence of your choice?

Good idea sickpig

To see how simple this is see above..

I thought it would be better trying to create a pdf rather than an image file for several reasons - easier to print, easier to copy and paste text should it be a digital cold storage file, nicer fonts etc.

example output..(resolution a bit lower than actual ..)

Ok final update before I move on..
The PDF output is now the following - a super paper wallet containing all private keys, multi signature address and the spending script, but also individual n pdf's each containing a single private key, the multisig address and the script for distribution.

Hope someone finds it useful.

Wow this is nice!

I think I'll wait for a few people to check the code to make sure everything is generated properly. It looks very nice though. . and I think I'll try to use it for some of my cold storage.

you can check it works by manually entering the generated multi-sig details into

That also allows you to spend your multi sig funds..

One final note the pdf works great but pasting from a pdf has an annoying bug which you should be aware of when copying the multi-sig script. You should copy and paste the script into a text editor and remove the added spaces at the end of each line. If you don't do this then the script has extra spaces at the end of each line and won't process! This is only a problem when you paste more than one line from the pdf so it only applies to the script, not the private keys.
