Description AndreY 2008-06-27 04:30:57 UTC 
Version:           2.6.4 (using 3.5.9, compiled sources)
Compiler:          Target: i586-manbo-linux-gnu
OS:                Linux (i686) release 2.6.24.4-desktop-1mnb

It possible to create archives with password (i.e. encripted) with 7z command line archiver. Ark can't extract such archive by any way: there is not password request and not extraction occurs.
Comment 1 AndreY 2008-06-27 07:38:43 UTC 
It relate to 7z archives with encripted headers (7z a -mhe=on -pQWERTY FILES.7z FILES) and with not encripted headers (7z a -pQWERTY FILES.7z FILES).
Comment 2 Yew Ming Chen 2008-08-23 12:53:00 UTC 
KDE4 ark's new 7zip plugin should be able to extract password protected files but not for encrypted headers yet.

SVN commit 883280 by ymchen:

7zip-plugin uses KPtyProcess to enable password querying. Now can list 
archives with encrypted headers (-mhe option)

Comment 4 Yew Ming Chen 2009-01-08 19:59:16 UTC 
tested working:
created an encrypted file with:
7z a -mhe -p12345 encrypted.7z  *.txt

then it can be opened and extracted with ark
