INTRODUCTION
------------
This simple program has been written in C and compiled with DICE (Free
Version). It is my first attempt to write a C program for Amiga
(see "Author" for more informations...).
It's an improved porting from my Unix Version (see "History").
However,it has been speeded up on Amiga, due to optimized code. This is
version 1.31. You can use it on BINARY files too...
REMEBER, THIS IS A BETA VERSION!
I HAVE NO RESPONSABILITY ABOUT DAMAGES AT YOUR SYSTEM.
SCrypter is very useful if used with DOPUS,assigning it to a button.
CONTENTS
--------
This archive includes a CLI-based command named SCrypter plus documents in
ASCII & Amigaguide format.This should be the archive contents:
- SCrypter
- SCrypter.doc
- SCrypter.guide
USE
---
SCrypter's use is very simple! Open a shell and type:
SCrypter OPT [infile] [outfile]
N.B.: Arguments HAVE TO BE at least three! No crash, however ;-)
OPT can be:
-c crypt You have to give all arguments (infile & outfile)
-d decrypt if you give only the source file, output will be displayed
in the current window else output will be putted in the
destination file.
If you are omitting an argument, SCrypter will show you a message with
the right use.
And now some numbers!
On a standard A500 7Mhz+512K Fast Ram, SCrypter worked so:
File Lenght Crypt/Decrypt Time cps SRC->DEST
----------- ------------------ --- ---------
4296 bytes 15-17 secs 252-283 RAM->RAM
15688 - 54-57 secs 275-290 RAM->RAM
325 - 3 secs 108 DSK->RAM
- - 2.5 secs 130 RAM->RAM
Well.You can see that SCrypter has been tested only on small files.
Speed is higher if SCrypter is used on larger files and source/dest
are both present in RAM DISK.
You shouldn't have problems using SCrypter with files larger than 16K.
SCrypter has been tested on these machines:
* A500 7Mhz 1MB RAM (512Chip + 512Fast), KS 1.2/1.3/2.0
* A1200 Standard
FUTURE
------
Next release will surely support a PASSWORD to crypt files. However, next
releases will be improved with:
* GUI
* File requester.
Look for them on Aminet,Your Local BBS,PD collection and more!
AUTHOR
------
This is my first attempt to program in C language on AMIGA systems.
I programmed (and i'm programming too...) with AMOS/AMOS PRO Basic and i
have written a lot of utilities and interesting applications. Some of them
are also present on Aminet. I started to use C some months ago, when i went
to the Department of Computers Science placed in Turin (Italy).

I would like to thank:
- Commodore for creating Amigas
- Amiga Technologies Gmbh. making Amiga stronger
- Francois Lionet for AMOS/AMOS Pro
- Nico Francois for PowerPacker library and more...
- All at AMOS-list (expecially Paul Hickman,Andy Church,Chris Hodges and
Mauro Fontana)
- Marco Musso,Diego Cortassa & Canardi Enrico
- My beta-testers: Dematteis Enrico

I hate PCs,Microsoft and anyone releated with them (Olivetti too...)
