BETA: PowerArchiver 2023 - 22.10.02

My apologies, I’m new to this whole “reporting a bug” thing.

PA 15.01.05
Windows 7 SP1, full updates.

This issue has been reproduced on 2 separate systems, both are the same OS and PA version.

I can reproduce this by using any of the AES encryption ciphers, it doesn’t happen with the old 2.04g cipher and non-encrypted files.

This is an example file. Explorer isn’t able to open the first AES file.
http://hackthegibson.net/tmp/test%20file.zip

On the broken AES file (exact duplicate of the other AES file), also notice the ‘packed’ size is different and the ‘CRC’ is blank in PA.

Everything works properly when I drag-drop the file into the archive, Windows 7 can read AES128.

I’ve pasted the full output of `zipinfo’ to http://pastebin.com/Vsvbmq9w

Look at file #3:
test file encrypted aes128.txt
compression method: unknown (99)
32-bit CRC value (hex): 00000000

While the functioning AES128 file, #4, reads as:
test file encrypted aes128 - WORKS.txt
compression method: deflated
32-bit CRC value (hex): 20e267dd

can you cab that file and send it to us via email? support@conexware.com
I cant download it from that site for some reason.

Are you sure that zip crypto is not being used in the case where it works? You can check method in PowerArchiver, right click on any of the list view columns and click on Method.

Thanks a lot!

All the files show as “DFLT-X”

As requested, the cab file has been emailed.

thanks - I will check it out and let you know.

Chris - how did you create one that works, via drag and drop? There seems to be a problem there, since that file is encrypted using zip crypto method (from 2.04g spec).

Keep in mind that there is a central and local directory in zip archive. Now our compression guys are already out, but I would not be surprised if this is done for compatibility reasons, so you would not try to enter password for unknown encryption dozen times.

i have written bug report for drag & drop - zip crypto creation… this should be corrected in next upcoming release, which should be quite soon. I will update this thread once we have that ready… thanks a lot for the report.

I am also setting up Win7 test computer to see if it actually supports aes, unfortunately i dont think thats the case - it was likely just confusion due to the bug in drag and drop.

thank you!!!

Correct, it worked when I used drag & drop. Thanks for finding the issue!

sorry about that Chris but big thanks for the report.

Here is the updated PA 2015 15.02.1 which fixes the bug with zipcrypto instead of AES when using drag and drop:
