In order to learn C programming, I am writing a file encryption program.
It's aiming for portability, so I'm using ANSI C code. It's still in the
early stages, but it's functional. I am distributing it under a GPL
license. The encryption can be cracked by brute force and some time on a
super computer, or maybe even a simple PC if you know what kind of data is
in the file. But that goes for any encryption. Given enought time, and
money, it can be cracked. I hope to improve the encryption in the future,
but for now, it's a neat little toy. Use it to hide your passwords from
other users if you keep the list on a shared computer. I am currently
looking for voluteers to write the help file. I'm horrible at writing
those. If your interested, just e-mail me. Also, be sure to read the
readme.txt files.

Version 0.4-beta still planning! Coming up in this version
(i'm still working on this so give me some time) a new layer of encryption
wich hashes out your key that you enter to make use of all char values
from 0-255 based on your key, and performs encryption using a 8192 bit key
period, even if you enter a 4 letter key! (why you would be dumb enough
to enter a 4 letter key i dunno but hey, some people are that
lazy! ::caugh caugh:: Big D you know who you are! Your the inspiration
for this anyway man!) So your actual encryption key will go from
"test" (or whatever lil' biddy thing you decide to pick, to some really
long password of 1kb worth of characters, some letters numbers and
symbols, and some unprintable characters that only the puter
understands. :o) Also, it will be using 4 32 bit hash values for some
password checking (hopefully to improve on this later), and the hash
values will also be used for encrypting data as well. And for those
people who need the program to encrypt really really large 75MB filez
(SJ, this ones for you m'lady, this knight will always be in your
service), there will be some routines added to work with the data in 32
bit chunks as well as reading and writing large chunks of data at the same
time to help minimize disk useage. And for vlade, dont worry, I'll find a
way to make it do entire directories for ya. May not be in this release,
but I'm working on it, time permitting. Also, greets goin
out to the kinkymonkey and cryptide for helping me out. ::gets off of his
soap box now::

Version 0.34 - Will contain the speed improvements mentioned above.
Still havnt gotten the huge encryption worked out yet. But a release is
long overdue. The road to 0.4 beta is coming soon so watch for it.
-
Version 0.33 beta is out! Basically it's a version 0.4 beta
pre-release. I have added menu's, and the keyfile encryption works. Not
sure if there are any bugs, but I havn't found any.
-
Version 0.3-beta It's primarily a bug-fix. The extra bytes bug
has been fixed! (woohoo!) Silly little bug actually. It seems that it
was encoding the eof marker, then creating a new one on each pass of the
data. Also, layer 4 encryption has been added. Also added - asks you if
you want to delete the original on encrypt and decrypt. For all the lazy
people, no more deleting it manually if your through with it. Yay! Also,
attempted to make the readme.txt file more helpful. Added changelog.txt
file to list changes and to keep a history of changes to the program.
-
0.2-alpha does contain one known bug. After you
decrypt it, the file contains about 8 extra bytes at the end of the file.
All your data is still fine however. I've tested it on gifs, jpgs, and
other executables with no ill effects. However, be warned that it's
there.
