Description

Hello,

from our bug tracking system:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=509091

To reproduce:

1. Create archive foo.zip with encrypted files like
$ echo "test" >foo.txt
$ zip -e -r foo foo.txt
  (Select an arbitrary password)

2. Start mc, select foo.zip on a panel, hit Enter and try to read or
   copy foo.txt

mc hangs up

It can be reproducible from 4.6.2 to the last version.

thank you very much

Denis Briand
mc Debian maintainer

How to recognize that file is enctypted and unzip is waiting for a password?

$ unzip -Z 1.zip
Archive: 1.zip 151 bytes 1 file
-rw-r--r-- 2.3 unx 5 tx stor 11-Mar-10 20:55 foo.txt
1 file, 5 bytes uncompressed, 5 bytes compressed: 0.0%
$ unzip -Z 2.zip
Archive: 2.zip 179 bytes 1 file
-rw-r--r-- 2.3 unx 5 TX stor 11-Mar-10 20:55 foo.txt
1 file, 5 bytes uncompressed, 5 bytes compressed: 0.0%

1.zip not enctypted
2.zip is enctypted

tx <-> TX

$ unzip -Zv foo |grep encr

file security status: encrypted

$ unzip -Zv f |grep encr

file security status: encrypted

$ unzip -Zv 4 |grep encr

file security status: not encrypted

for dirty hack need add -P option like this

uzip

 35 my $cmd_extract = "$app_unzip -p -P fakepassword";

Replying to angel_il:

$ unzip -Zv foo |grep encr

file security status: encrypted

$ unzip -Zv f |grep encr

file security status: encrypted

$ unzip -Zv 4 |grep encr

file security status: not encrypted

No-no-no... :) Once this output will changed and what we will do?
