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

The problem is the same as in #324920: mc starts a program to handle
the archive - unzip in the case here, that program tries to read the
password from stdin and fails.

OK, I think, the "vfext" should use

    unzip -Z -v test.zip |grep 'file security status:'

to determiner whether the file  is  encrypted  or  not  and  then  react
approriated...

Note:  I do not use the original "/usr/share/mc/extfs/unzip" which is
       writen in SHELL script (like the "tdmc_tar") and is working.

Hello,
I can reproduce this bug in 2:4.6.2-2 version also
When I hit "CTRL + C", I have that message:
"[/home/sid/foo.zip] foo.txt password: uzip (copyout): `unzip' failed
-non-zero exit status (80)"

Best regards
