python实现文件快照加密保护的方法_Python

本文实例讲述了python实现文件快照加密保护的方法。分享给大家供大家参考。具体如下：

这段代码可以对指定的目录进行扫描，包含子目录，对指定扩展名的文件进行SHA-1加密后存储在cvs文件，以防止文件被篡改

调用方法：python snapper.py > todayCheck.csv

				?

									# Hello, this is a script written in Python. See http://www.pyhon.org

									#

									# Snapper 1.2p

									#

									# This script will walk a directory (and its subdirectories) and compute

									# SHA (Secure Hash Algorithm) for specific files (according to their

									# extensions) and ouput a CSV file (suited for loading into a spreadsheet

									# editor,a database or simply comparing with diff or ExamDiff.).

									#

									# You can redirect the output of this script to a file.

									# eg. python snapper.py > todayCheck.csv

									#

									# This script can be usefull to check system files tampering.

									#

									# This script is public domain. Feel free to reuse it.

									# The author is:

									#    Sebastien SAUVAGE

									#    <sebsauvage at sebsauvage dot net>

									#    http://sebsauvage.net

									#

									# More quick & dirty scripts are available at http://sebsauvage.net/python/

									#

									# Directory to scan and extensions are hardcoded below:

									directoryStart = r'c:\windows'

									extensionList=['.exe','.dll','.ini','.ocx','.cpl','.vxd','.drv','.vbx','.com','.bat','.src',

									        '.sys','.386','.acm','.ax', '.bpl','.bin','.cab','.olb','.mpd','.pdr','.jar']

									import os,string,sha,stat,sys

									def snapper ( directoryStart , extensionList ) :

									  os.path.walk( directoryStart, snapper_callback, extensionList )

									def snapper_callback ( extensionList , directory, files ) :

									  sys.stderr.write('Scanning '+directory+'\n')

									  for fileName in files:

									    if os.path.isfile( os.path.join(directory,fileName) ) :

									      if string.lower(os.path.splitext(fileName)[1]) in extensionList :

									        filelist.append(fileSHA ( os.path.join(directory,fileName) ))

									def fileSHA ( filepath ) :

									  sys.stderr.write(' Reading '+os.path.split(filepath)[1]+'\n')

									  file = open(filepath,'rb')

									  digest = sha.new()

									  data = file.read(65536)

									  while len(data) != 0:

									    digest.update(data)

									    data = file.read(65536)

									  file.close()

									  return '"'+filepath+'",'+str(os.stat(filepath)[6])+',"'+digest.hexdigest()+'"'

									sys.stderr.write('Snapper 1.1p - http://sebsauvage.net/python/\n')

									filelist = []

									snapper( directoryStart , extensionList )

									sys.stderr.write('Sorting...\n')

									filelist.sort()

									filelist.insert(0, '"File path","File size","SHA"' )

									sys.stderr.write('Printing...\n')

									for line in filelist:

									 print line

									sys.stderr.write('All done.\n')

希望本文所述对大家的Python程序设计有所帮助。
