Re: [Dar-support] Unexpected password prompt when isolating an encrypted archive

[Denis C. <dar...@fr...>]

I guess you make a confusion between -K and -J options

-K is to be used for the object of the operation (the archive you 
create, the isolated catalog you create, the archive you test, list, 
extract data from...)

-J option apply to the archive of reference (the one given to -A 
option), here the archive you take as reference to isolate a catalog.

the same way '-$' option (pay attention to the quote if given on shell 
prompt), applies to the auxiliary archive of reference (see -@ option)

note that -K is only mandatory if you want to cipher the archive (or 
isolated catalog, which is just a particular type of archive) about to 
be created.

When reading an archive, if -K -J or '-$' is not specified and the 
corresponding archive is ciphered, dar will issue a prompt for you 
provide the password (this is what you got here without -J option).

I would suggest setting the lennz-darrc file more or less that way:

#-------
all:
   -K aes:secret

reference:
   -J aes:secret
#-------

I let you read the conditional syntax paragraph in dar man page for more 
information on that syntax and if you want to do more funny things:
http://dar.linux.free.fr/doc/man/dar.html#CONDITIONAL%20SYNTAX

Cheers,
Denis
