What
is it?
corundum
is the rewriten, brand-new version of sapphire.
It is a steganographic program that will take
text you have written, and encode it as a picture.
The text can be encoded with Blowfish for more
secure encryption. corundum will now store the
text in any of the 4* layers in a picture. The
encoded text is now easily hidden with the new
location, and shade features of corundum.
*You
must be using a 32bit picture to utilize the Alpha
layer, or else only the red, blue, and green layers
of a picture are editable.
The
resulting picture will be a BMP, PNG, or TIF file.
These are the only 3 popular file formats that
retain encoding details in 32bits. If the pictures
are compressed after being stamped, the stamp
could be lost, thus JPEG files are fundamentaly
flawed for steganography.
Price
$9
for one license, and $14 for a two-person licence
for you and your friend. All who purchased sapphire
previous to March 16, 2002 are entitled to a free
upgrade. Please e-mail

Encryption
Abilities
•Blowfish
encryption has now been added. Your text can be
up to 128 bit encoded!
•Encryption
algorithms are expensive, and involve all sorts
of legal issues. Because of this it is difficult
to implement encryption schemes such as PGP.
Augmentation
Abilities
•Shading
now can make your text almost invisble, or at
least less conspicuous.
•The
4 layers used for 32bit pictures allow for more
versatility when attempting to be subtle.
•You
can now determine the location of the encoded
text in your picture to hide it better.
•Borders
can be automaticly added as a place to hide encrypted
text.
•Statistics
are now easily available to check your picture.
•Simple
decryption allows for no-hassles.
