** Summary changed:
- file-roller will not open 256 AES zip files
+ unzip will not open 256 AES zip files
** Description changed:
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:
+ protected by 256 AES encryption. Unzip in ubuntu cannot handle these

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

7-Zip 4.51 beta Copyright (c) 1999-2007 Igor Pavlov 2007-07-25

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?
