毕设做网站是不是太low,做网站应该买什么服务器,枣庄有做网站的吗,服务器网站慢的原因Python解包及反编译: PyInstaller Extractoruncompyle6
python exe 反编译
pythonexe解码
1、安装pyinstxtractor
新建一个py文件pyinstxtractor.py,然后将下面的内容拷贝进去 然后就安装好了#xff0c;要使用的时候与待解包的exe文件放在同一文件夹即可
uncompyle6python exe 反编译pythonexe解码1、安装pyinstxtractor新建一个py文件pyinstxtractor.py,然后将下面的内容拷贝进去 然后就安装好了要使用的时候与待解包的exe文件放在同一文件夹即可 PyInstaller Extractor v2.0 (Supports pyinstaller 6.6.0, 6.5.0, 6.4.0, 6.3.0, 6.2.0, 6.1.0, 6.0.0, 5.13.2, 5.13.1, 5.13.0, 5.12.0, 5.11.0, 5.10.1, 5.10.0, 5.9.0, 5.8.0, 5.7.0, 5.6.2, 5.6.1, 5.6, 5.5, 5.4.1, 5.4, 5.3, 5.2, 5.1, 5.0.1, 5.0, 4.10, 4.9, 4.8, 4.7, 4.6, 4.5.1, 4.5, 4.4, 4.3, 4.2, 4.1, 4.0, 3.6, 3.5, 3.4, 3.3, 3.2, 3.1, 3.0, 2.1, 2.0) Author : Extreme Coders E-mail : extremecoders(at)hotmail(dot)com Web : https://0xec.blogspot.com Date : 26-March-2020 Url : https://github.com/extremecoders-re/pyinstxtractor For any suggestions, leave a comment on https://forum.tuts4you.com/topic/34455-pyinstaller-extractor/ This script extracts a pyinstaller generated executable file. Pyinstaller installation is not needed. The script has it all. For best results, it is recommended to run this script in the same version of python as was used to create the executable. This is just to prevent unmarshalling errors(if any) while extracting the PYZ archive. Usage : Just copy this script to the directory where your exe resides and run the script with the exe file name as a parameter C:\\path\\to\\exe\\python pyinstxtractor.py filename $ /path/to/exe/python pyinstxtractor.py filename Licensed under GNU General Public License (GPL) v3.

CHANGELOG Version 1.1 (Jan 28, 2014) ------------------------------------------------- - First Release - Supports only pyinstaller 2.0 Version 1.2 (Sept 12, 2015) ------------------------------------------------- - Added support for pyinstaller 2.1 and 3.0 dev - Cleaned up code - Script is now more verbose - Executable extracted within a dedicated sub-directory (Support for pyinstaller 3.0 dev is experimental) Version 1.3 (Dec 12, 2015) ------------------------------------------------- - Added support for pyinstaller 3.0 final - Script is compatible with both python 2.x 3.x (Thanks to Moritz Kroll Avira Operations GmbH Co. KG) Version 1.4 (Jan 19, 2016) ------------------------------------------------- - Fixed a bug when writing pyc files version 3.3 (Thanks to Daniello Alto: https://github.com/Djamana) Version 1.5 (March 1, 2016) ------------------------------------------------- - Added support for pyinstaller 3.1 (Thanks to Berwyn Hoyt for reporting) Version 1.6 (Sept 5, 2016) ------------------------------------------------- - Added support for pyinstaller 3.2 - Extractor will use a random name while extracting unnamed files. - For encrypted pyz archives it will dump the contents as is. Previously, the tool would fail. Version 1.7 (March 13, 2017) ------------------------------------------------- - Made the script compatible with python 2.6 (Thanks to Ross for reporting) Version 1.8 (April 28, 2017) ------------------------------------------------- - Support for sub-directories in .pyz files (Thanks to Moritz Kroll Avira Operations GmbH Co. KG) Version 1.9 (November 29, 2017) ------------------------------------------------- - Added support for pyinstaller 3.3 - Display the scripts which are run at entry (Thanks to Michael Gillespie malwarehunterteam for the feature request) Version 2.0 (March 26, 2020) ------------------------------------------------- - Project migrated to github - Supports pyinstaller 3.6 - Added support for Python 3.7, 3.8 - The header of all extracted pycs are now automatically fixed from __future__ import print_function import os import struct import marshal import zlib import sys from uuid import uuid4 as uniquename class CTOCEntry: def __init__(self, position, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name): self.position position self.cmprsdDataSize cmprsdDataSize self.uncmprsdDataSize uncmprsdDataSize self.cmprsFlag cmprsFlag self.typeCmprsData typeCmprsData self.name name class PyInstArchive: PYINST20_COOKIE_SIZE 24 # For pyinstaller 2.0 PYINST21_COOKIE_SIZE 24 64 # For pyinstaller 2.1 MAGIC bMEI\014\013\012\013\016 # Magic number which identifies pyinstaller def __init__(self, path): self.filePath path self.pycMagic b\0 * 4 self.barePycList [] # List of pycs whose headers have to be fixed def open(self): try: self.fPtr open(self.filePath, rb) self.fileSize os.stat(self.filePath).st_size except: print([!] Error: Could not open {0}.format(self.filePath)) return False return True def close(self): try: self.fPtr.close() except: pass def checkFile(self): print([] Processing {0}.format(self.filePath)) searchChunkSize 8192 endPos self.fileSize self.cookiePos -1 if endPos len(self.MAGIC): print([!] Error : File is too short or truncated) return False while True: startPos endPos - searchChunkSize if endPos searchChunkSize else 0 chunkSize endPos - startPos if chunkSize len(self.MAGIC): break self.fPtr.seek(startPos, os.SEEK_SET) data self.fPtr.read(chunkSize) offs data.rfind(self.MAGIC) if offs ! -1: self.cookiePos startPos offs break endPos startPos len(self.MAGIC) - 1 if startPos 0: break if self.cookiePos -1: print([!] Error : Missing cookie, unsupported pyinstaller version or not a pyinstaller archive) return False self.fPtr.seek(self.cookiePos self.PYINST20_COOKIE_SIZE, os.SEEK_SET) if bpython in self.fPtr.read(64).lower(): print([] Pyinstaller version: 2.1) self.pyinstVer 21 # pyinstaller 2.1 else: self.pyinstVer 20 # pyinstaller 2.0 print([] Pyinstaller version: 2.0) return True def getCArchiveInfo(self): try: if self.pyinstVer 20: self.fPtr.seek(self.cookiePos, os.SEEK_SET) # Read CArchive cookie (magic, lengthofPackage, toc, tocLen, pyver) \ struct.unpack(!8siiii, self.fPtr.read(self.PYINST20_COOKIE_SIZE)) elif self.pyinstVer 21: self.fPtr.seek(self.cookiePos, os.SEEK_SET) # Read CArchive cookie (magic, lengthofPackage, toc, tocLen, pyver, pylibname) \ struct.unpack(!8sIIii64s, self.fPtr.read(self.PYINST21_COOKIE_SIZE)) except: print([!] Error : The file is not a pyinstaller archive) return False self.pymaj, self.pymin (pyver//100, pyver%100) if pyver 100 else (pyver//10, pyver%10) print([] Python version: {0}.{1}.format(self.pymaj, self.pymin)) # Additional data after the cookie tailBytes self.fileSize - self.cookiePos - (self.PYINST20_COOKIE_SIZE if self.pyinstVer 20 else self.PYINST21_COOKIE_SIZE) # Overlay is the data appended at the end of the PE self.overlaySize lengthofPackage tailBytes self.overlayPos self.fileSize - self.overlaySize self.tableOfContentsPos self.overlayPos toc self.tableOfContentsSize tocLen print([] Length of package: {0} bytes.format(lengthofPackage)) return True def parseTOC(self): # Go to the table of contents self.fPtr.seek(self.tableOfContentsPos, os.SEEK_SET) self.tocList [] parsedLen 0 # Parse table of contents while parsedLen self.tableOfContentsSize: (entrySize, ) struct.unpack(!i, self.fPtr.read(4)) nameLen struct.calcsize(!iIIIBc) (entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) \ struct.unpack( \ !IIIBc{0}s.format(entrySize - nameLen), \ self.fPtr.read(entrySize - 4)) try: name name.decode(utf-8).rstrip(\0) except UnicodeDecodeError: newName str(uniquename()) print([!] Warning: File name {0} contains invalid bytes.
