Zip加密文件字典破解Python实现

最近在看《Violent Python》，记录一些代码实现。

0x00 Zip加密文件字典破解Python实现

本例使用Python zipfile模块用来做zip格式编码的压缩和解压缩，顺带使用了optparse模块和threading模块。

0x01 代码实现

import zipfile
import os
from optparse import OptionParser 
from threading import Thread
def extractFile(zFile, password):
    try:
	zFile.extractall(pwd=password)
	print '[+] Found password ' + password + '\n'
    except:
	pass
def checkFile(filename):
    if not os.path.isfile(filename):
	print '[-] ' + filename + ' does not exist.'
	exit(0)
    if not os.access(filename, os.R_OK):
	print '[-] ' + filename + ' access denied.'
	exit(0)
def main():
    parser = optparse.OptionParser(usage="usage%prog " + "-f  -d ", version="%prog v1.0")
    parser.add_option('-f', '--filename', dest='zipfile', type='string', help='specify zip file')
    parser.add_option('-d', '--dictionary', dest='dicfile', type='string', help='specify dictionary file')
    (options, args) = parser.parse_args()
    if (options.zipfile == None) | (options.dicfile == None):
	print parser.usage
	exit(0)
    else:
	zip_file = options.zipfile
	dic_file = options.dicfile
    checkFile(zip_file)
    checkFile(dic_file)
    zFile = zipfile.ZipFile(zip_file)
    passFile = open(dic_file)
    for line in passFile.readlines():
	password = line.strip('\n')
	t = Thread(target=extractFile, args=(zFile, password))
	t.start()
if __name__ == '__main__':
    main()
