Review:
Take a close look at this graphic... See anything strange? Just looks like a standard trippy background from my mass collective...

Well, what you see is deceiving... What's really being shown is, in fact, one of my trippy backgrounds; however... It's been Steganographied...

Steganography is the name of today's program that I had the pleasure of playing with, it's pretty nice... What you can take and do is embed content into files; such as here I've embedded the message "You're looking at Gizmo's Stenography!" (or something along those lines)...

Not only does it hide your files, content, or messages... It also encrypts them with a 256bit key that uses your password as the phraise...

To read the message? You need Steganography and my password (test)... What you can now do is decipher my image and get the message. You can also choose to save the content to another file...

What does this mean? You can securely and privately share files with people; who would look at a jpg thinking it was a list of content ;\) ...

All in all I LOVE this piece of software, it's a great idea and works pretty well...

Well, I just used BeyondCompare to compare the Steganographied graphic to the Non-Steganographied graphic to note the updates to the file. Sure enough, as to not currupt the original file, the new data is added to the end of the file, in fact it sits on the last line (well my 2 part message does, i can't validate this for files).

Original:
Code:

New:
Code:

So the updated is logically:

&#61696;
Please note, I added the extra returns to clean up what will be displayed on the forums.

Also, my 2 line message only added 1k to the image file.
