1. Introduction
===============

                          Introduction
                          ------------

XCrypt is a short, handy, and easy-to-use Cryptor tool that makes
use of the crypt libraries supplied with the XPK package.

You may use either the FEAL or the IDEA algorythm, whereby IDEA
is preferred by default.



2. Documentation

2.1. System requirements
------------------------

                       System requirements
                       -------------------

You need Kickstart 2.0 or higher to run XCrypt. In addition to
that, XCrypt requires the xpkmaster.library and at least the
xpkIDEA.library.


2.2. Shell usage
----------------

                           Shell usage
                           -----------


 You cannot start XCrypt from the Workbench, it's a shell tool!


 Template:        XCrypt SOURCE/A,FEAL/S,PW/K/A,QUIET/S

 You must specify at least a source file and a password that will
 be used for (de)cryption. The PW keyword has to be specified.
 
 Example:         XCrypt dh1:SecretData.TXT PW SafeForEver

 this will (de)crypt the file SecretData.TXT using the password
 "SafeForEver". If XCrypt detects that the input file is already
 crypted, it will decrypt it using the specified password.
 
 Keep in mind that the source and destination files are
 identical, that means the original file will be overwritten. You
 better don't forget the password used for encryption - otherwise
 all data are lost forever.

 Additionally, you may specify the FEAL keyword. XCrypt will then
 use the FEAL algorythm instead of IDEA. Last not least you can
 use the QUIET keyword for suppressing any text output.


2.3. DirectoryOpus installation
-------------------------------


                   DirectoryOpus installation
                   --------------------------

 XCrypt was created for the usage inside of DirectoryOpus. To
 configure a XCRYPT button or menu, proceed like this:


              AmigaDOS   c:xcrypt {f} pw {RsEnter password}

              Flags: Rescan source
