zipfile

Is there a way to decompress an AES-128 encrypte file directly with python, since ZipFile throws a Bad Password error. If i use 7zip it works, so the password is correct, but then again 7zip needs to be installed as a dependency. What i tried: from ZipFile import ZipFile zip = ZipFile('test.zip') zip.extractall(pwd='password') This throws the Bad Password exception. Checking the file with 7zip 7z l -slt test.zip This returns: Encrypted = + Method = pkAES-128 Deflate The zipfile module from the Python standard library supports only CRC32 encrypted zip files (see here: http://hg.python.org

This question already has an answer here: Automate zip file reading in R 9 answers I need to unzip multiple files at once and add it as a data frame in my R dashboard. I'm currently using this code: zipF<- "/Users/sahilverma13/Desktop/chat_data_2017-01-30_IST.zip" outDir<-"/Users/sahilverma13/Desktop" unzip(zipF,exdir=outDir) But I have to do it for every file separately. zipF <- list.files(pattern="*.zip") I tried using the wildcard but it doesn't work. Please help. I often use the ldply function from the plyr package to read or do stuff with multiple files. library(plyr) # get all the zip

I have a script that creates zip files of dirs containing symlinks. I was surprised to find that the zipfiles have zipped the targets of the links as opposed to the links themselves, which is what I wanted and expected. Anyone know how to get zipfile to zip the links? ivan_pozdeev zipfile doesn't appear to support storing symbolic links. The way to store them in a ZIP is actually not part of the format and is only available as a custom extension in some implementations . In particular, Info-ZIP's implementation supports them so you can delegate to it instead . Make sure your decompression

If I am unzipping a Zip file with the Python ZipFile library, where the file was created on Windows, but my code is running on Unix-like, will the path separators always be Unix-style? Internally, ZipFile stores forward slashes as required by the zip file specification . Externally, they get translated using os.sep so it will match what is normally expected on a given platform.

I am using Python 2.7 on Windows 7 (64 bit). When I try to unzip a zip file with ZipFile module I get the following error:- Traceback (most recent call last): File "unzip.py", line 8, in <module> z.extract(name) File "C:\Python27\lib\zipfile.py", line 950, in extract return self._extract_member(member, path, pwd) File "C:\Python27\lib\zipfile.py", line 993, in _extract_member source = self.open(member, pwd=pwd) File "C:\Python27\lib\zipfile.py", line 897, in open raise BadZipfile, "Bad magic number for file header" zipfile.BadZipfile: Bad magic number for file header WinRAR could extract the

I'm creating an encrypted zip file using DotNetZip using WinZip AES 256. However I'm able to read the directory and even to remove some of the zipentries without having the encryption key. As far as I understand the directory visibility is a limitation of the Zip format. I just wonder, if this also applies for any changes in removing / adding components to the zip file or does there exist a way for preventing such changes. EDIT: A quick read of Zip File Format seems to show, that double zipping seems to be the only solution to prevent random removal / addition of comoponents in a zipfile,

System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, extractPath); Using ZipFile in C#, I'm trying to extract a file from a known location and it is throwing the following error: System.IO.Exception: Zip entry name ends in directory separator character but contains data I've done some research, ExtractToDirectory is explained in MSDN but couldn't find this error definition. Would you be able to explain why this error is happening?
