Minimal Bitcoin address generator in Python
Software engineer interested in free software development process.
Most recently tested Pieter Hintjens' Collective Code Construction Contract with https://magicstone.dev
"Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)" is the error I get running linux.
The OSX patch doesn't work either, the command "arch -i386" fails.
Already changed default to compressed=False but now need to figure out the flaw in generating compressed keys.
Hi there,
would it be possible to implement the generation of addresses other than Bitcoin via passphrases?
Cheers.
Hi @weex, I know this is a very noob question since I've started with Python (v2.7.10) just yesterday and ctypes is unable to find the ssl library on this line:
ssl = ctypes.cdll.LoadLibrary (ctypes.util.find_library ('ssl') or 'libeay32')
Having exhausted my google skills, could you please tell me what I'm missing here? I do see the following:
Thanks for this code, it is really helpful!
Out of the box I have an issue though:
On OSX when I do a simple python addrgen.py I get a segmentation fault: 11
Has anyone else had success running this on OSX? I'm assuming it has to do with either a) I have multiple python versions b) cytpes doesn't work as expected on osx c) ?
Any advice would be appreciated! I am just trying to generate a deterministic bitcoin address from a secret.

raise TypeError(init)
TypeError: 32.75
From reading other comments about ctypes and MacOS I worked out the problem is due to pointer types getting resolved down to integers. The suggested fix is to create a type derived from ctypes.c_void_p and use that as restype. Indeed this fixes the problem, patch is attached.
