John the Ripper application question

Hi Friends

I like to know one thing the how exactly john the ripper works. I have search in google, read lots of tutorial on that.

I have simple question, can I get the password for the encrypted file for the following example.

e.g :

Abc.txt file

contents

"This is Joy"

Now I have encrypted the file using gpg and the password is 123.

I got the file Abc.txt.gpg.

Can I get the password using john the ripper while passing Abc.txt.gpg as input?

Thanks in Advance.

Joy

MAILER(8)						      System Manager's Manual							 MAILER(8)

NAME

       mailer - script to warn users about their weak passwords

SYNOPSIS

       mailer password-files

DESCRIPTION

       This  manual  page  documents  briefly  the mailer command, which is part of the john package.  This manual page was written for the Debian
       GNU/Linux distribution because the original program does not have a manual page.  john, better known as John the Ripper, is a tool to  find
       weak passwords of users in a server.
       The mailer tool is useful to inform users which have been found to be using weak passwords by mail.

       You  should edit the message mailer will send to the users, but remember to copy the script to a safe place before editing it, as it's gen-
       erally a bad idea to modify things living in /usr.

SEE ALSO

       john(8), unafs(8), unique(8), unshadow(8).

       The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on
       your system.

AUTHOR

       This manual page was written by Jordi Mallach <jordi@debian.org>, for the Debian GNU/Linux system (but may be used by others).
