2014-12-12 08:25:34 penalvch summary file-roller will not open 256 AES zip files unzip will not open 256 AES zip files
2014-12-12 08:26:15 penalvch description Binary package hint: file-roller Winzip and many other zip programs can now produce zip files that are protected by 256 AES encryption. FIle-roller in ubuntu cannot handle these zips. The files within the zips are shown fine but when you try and extract the following error occurs: skipping: Test.txt unsupported compression method 99 I believe this is because "unzip" is used to extract the archive. This is the output from "unzip": dbrewer@HCC122J:~/Desktop$ unzip Test.zip Archive: Test.zip skipping: Test.txt unsupported compression method 99 If "7z" is used it works fine: dbrewer@HCC122J:~/Desktop$ 7z x Test.zip 7-Zip 4.51 beta Copyright (c) 1999-2007 Igor Pavlov 2007-07-25 p7zip Version 4.51 (locale=en_GB.UTF-8,Utf16=on,HugeFiles=on,2 CPUs) Processing archive: Test.zip Extracting Test.txt Enter password (will not be echoed) : Everything is Ok So I propose that file-roller uses "7z" instead of "unzip". I attach an example of this kind of file. The password is "monkey" (no quotes). Note peazip also can handle this. Maybe a replacement for file-roller?
