Multisignature paper wallet creator which outputs a pdf..

Simply copy the .py file and a suitable background picture to your computer and run with python.

You will need to install the following modules for python: pybitcointools, PIL, fpdf and qrcode, like so: sudo pip install bitcoin etc..

The script simply asks for and m of n combination (n is total number of keys involved in creating the multisignature bitcoin address, m is the number of keys required to spend the funds). The script supports up to an n of 12. Keys can be randomly generated or provided by the user (or a combination of the two).

The script then creates an A4 pdf containing the details of m-of-n, the multisignature bitcoin address and qr code, all private keys and qr codes, and the multisignature script. The script then gives the option to create distributable individual A4 pdf files for each private key which contains m-of-n details, the private key, multi-signature address and multi-sig script, with of course QR codes for importation purposes. Use of PDF allows the script to be copy and pasted easily from digital cold storage.

Example output is contained in the mspw.pdf file here on github.

Todo:

  1. minor formatting error if n > 10 as goes onto third page.

  2. allowing bip38 functionality for printed private keys..(m of n with bip38 encrypted private keys used)

  3. finish a spending script that comes with it..:)
