PACL AES-encrypted archives incompatible with Powerarchiver
-
Some time ago I reported a problem with AES-encrypted archives to support. AES-encrypted archives with PACL can’t be extracted with Powerarchiver 9.x. When will this problem be solved?
-
Send us ZIP file if possible, how large was it?
thanks,

There are a couple of reason for not sending the zip-archive:
1. It’s 280 MB+
2. It’s a zipped archive of my personal files which I’m not keen on sharing with others.Very early in the extraction or the testing of the file woth PA 9.01 I get a CRC error
Testing: Documents and Settings\Arild\Mine dokumenter\IKT\GnuPG\Installasjon\diskett\gnupg\secring.gpg
–> CRC ERROR
–> CRC ERRORI use the following string in my bat-file:
pacomp -u -r -P -t -e1 -sNotDisclosed -x@utan.txt c:\skopi%USERNAME%.zip “%USERPROFILE%\Mine dokumenter*." "%USERPROFILE%\Favoritter*.” “%USERPROFILE%\Skrivebord*." "%USERPROFILE%\Start-meny*.” "%USERPROFILE%\Programdata*." "%USERPROFILE%\Lokale innstillinger\Programdata*.
With ordinary zip-encryption I get no error. Both AES-128 and 256 gives the same CRC Error in PA 9.01. Extraction or testing wit PAEXT yields no error.
Using the same PACOMP-string on my wifes account yields no errors in PA 9.01, but she has only about 5 MB of zipped files.

I’ve tested PACL 4.00 Beta 1. It gives the same result at PACL 3.51

the problem might be the filenames of the files and the characters used with them. can you list all file names of the files and what are in them your wifes zip and yours. please and are you using xp or windows 98

I’ve examined the archive and I think I’ve found the what causes. The secring.gpg is a 0-byte file. It’s the first 0-byte file in the archive. I then zipped a new file where I excluded all *.gpg-files. I have several 0-byte files. This time PA 9.01 stopped, again, on the first 0-byte file it encountered with CRC Error.
I’m using:
Windows XP Norwegian with the latest updates. SP2 is not yet available.
PA 9.01.01
PACL 4.00 Beta 1 or PACL 3.51 -
basically your saying 0 byte files are the problem. if they register too low then this program will fail, and produce aes archives that fail.

The archives tests and extracts, as far as I can see, OK with PACL. But you can not use Powerarchiver 9.x to extract an archive protected with AES containing 0 byte files.

Still can’t extract AES-encrypted archives created with pacomp using Powerarchiver v. 9.02.00.

this is due to the error in PACL when encrypted file is 0 byte. It will be fixed in next PACL release…
