Unzip AES Strong-Encrypted Zip
Python code to unzip a 128-bit AES Encrypted Zip. # file: UnzipStrongEncrypted.py import chilkat # Simple example showing how to unzip a 128-bit WinZip AES strong-encrypted .zip file. zip = chilkat.CkZip() zip.UnlockComponent("anything for 30-day trial") # Setting Encryption = 4 indicates an WinZip AES encrypted zip zip.put_Encryption(4) zip.put_EncryptKeyLength(128) zip.SetPassword("secret") # With WinZip AES Encryption, the zip can be opened even if the password # is incorrect. This is standard, and you'll find the same behavior with # the WinZip program. success = zip.OpenZip("strongEncrypted.zip") if success: # The zip in this example contains these files and directories: # exampleData\ # exampleData\hamlet.xml # exampleData\123\ # exampleData\aaa\ # exampleData\123\hello.txt # exampleData\aaa\banner.gif # exampleData\aaa\dude.gif # exampleData\aaa\xyz\ # Returns -1 if error, otherwise returns the number of files and directories # unzipped. # In this example, Unzip will create the directory "unzipDir" in the current # working directory (if it does not already exist) and unzip into it. # If the password is incorrect, numUnzipped will return either -1 or the number # of files successfully unzipped. Technically (but not likely) it is possible to # create a zip that contains some encrypted files and some unencrypted files. numUnzipped = zip.Unzip("unzipDir") print "numUnzipped = " + str(numUnzipped) + "\n" else: # Failed to open the .zip archive. zip.SaveLastError("openZipError.txt") |
