Giveaway of the day — Ultima Steganography
Ultima Steganography era disponibile come app gratuita il 22 agosto 2010!
Ultima Steganography è un software per la steganografia molto facile da usare destinato ai sistemi Windows. Grazie ad esso, potrete cifrare facilmente dei file e nasconderli all'interno di immagini.
Una volta che un file è stato nascosto in un'immagine, l'immagine salvata rimane tale e può essere visualizzata come qualsiasi altra immagine, l'unica differenza è che in essa sono nascosti dei file. La sicurezza e l'integrità dei file sono due delle più grandi problematiche del mondo tecnologico. Tenete i vostri dati al sicuro con Ultima Steganography.

This program works, just be sure to put the files in a .zip or .rar to prevent data loss....
There's clearly a great deal of confusion over this. Steganography is hiding data in an image by placing it in the low-order bits of the pixels, typically indistinguishable from noise if the data is encrypted, and if done right, invisible to the human eye. I can't guarantee that Ultima Steganography did this correctly, but it appears that they did. How much data you can hide is limited not by the filesize of the source image, but by its dimensions. More pixels can hide more data. If people can't figure out what to do with this, they don't understand security. It's exceptionally difficult to determine whether steganography has been used. Maybe the NSA knows something about the mathematical properties and probabilities that the rest of us don't, but otherwise it's undetectable if done correctly. The source image should be somewhat random, such as a photograph, not a screenshot or graphic.
#11, Allan Benson, Enplase has had many giveaways here, so they aren't unknown. It's true that their website sucks and that their code quality is low, but that's true of many giveaway vendors.
The install of Ultima Steganography was very clean and simple. The dialogs open in the middle of the full desktop instead of the current monitor (highly annoying). The decryption source-file selection dialog appears incorrect, as it will accept more filetypes than encryption outputs.
#2, Freak, #4, Best of the web, those things don't do steganography, they merely append data to the image file, which is easily detected.
#6, Inas, not being able to restore the data without the original password isn't a "con", it's called security, it means that there are no backdoors. Your alternatives don't do steganography.
This is one of the few offerings from Enplase that I like. I can't guarantee that it's bug-free, but it appears to do what it says, which can be handy. Images containing steganography can be publicly posted, and no one will be the wiser.
The Wolfram Blog just had an article on steganography using Mathematica. People unfamiliar with steganography should read it.
PROS:
* Smooth download, installation, activation, registration on Vista x32 OS.
* Program is very easy to use, with given, simple step-by-step instructions.
* Seems to support most of the popular image input formats
* Supports image output format of: png, bmp, tif, tiff
* Supports enryption method: XTEA (128-bit)
* Supports use of key/password to unlock file encryption.
* I easily encrypted a word document within a gif image.
* I was able to easily unencrypt the file, via chosen password.
CONS:
* If user forgets chosen key/password, encrypted file is unrecoverable.
* program supports limited image output formats (only png, bmp, tif, tiff).
* extracted file (when saved to same name as original file) overwrote original file, which was then rendered unreadable in ".doc" format. This may be the normal encryption protocol - but for novice users, this fact may not be so obvious from the get-go, so clear, up-front instructions about this process would be helpful.
Summary: Program is easy to use and does as it says, so a 2-thumbs-up for today's offer - thanks, GOTD & Enplase.

Like most people I suspect, I had a look around the publisher's website before I even looked at the software, and to be honest I wasn't all that impressed. Before downloading anything, I like to know who I am 'dealing' with, and to be honest, the lack of contact details other than eMail and a simple contact form didn't inspire me to proceed. I have no doubt that this software will do what it says it does (although the Jury is out on that one looking at the comments to date), but persona means a great deal, and this company/business/corporation doesn't inspire me to proceed any further.
Hiding messages and data in an image has a limited application for the average user anyway, certainly I am at a loss to see why I would personally want to do this, so a fuller explanation as to the why, how and when would be better than just repeating the intro on GOTD, almost exactly what's on the publisher's website.
To summarise, I am not all that happy with the publisher, no inference intended at your undoubted professional skills, but I think you should put more detail on your website if only to inspire confidence in the end-user.
I'm getting this error when I attempt to run the program (on WinXP):

Ottimo programma per nascondere virus all'interno di immagini... =| Una persona che usa normalmente il pc dubito che faccia molto uso di questo programma...

Per esempio con Photoshop se voglio salvare in TIF, lui mi mette tra parentesi (TIF, TIFF) senza possibilita' di scelta tra l'uno e l'altro, e me lo salva in .TIF. Boh magari in passato si usava l'estensione del file con 2 effe poi han deciso di toglierne una.
Chissa' se il professore "SO TUTTO IO LOL LOL" dall'alto della sua grande sapienza si abbassi a darci in merito maggiori dettagli ;-)

Quindi, Mero, se tiff è formato non è estensione. Probabilmente mi sono spiegato male, propongono tutti e due come estensione del nome file, l'estensione tiff e tif, come fossero diverse. Mi sa come di poca ... attenzione nella scrittura del codice :-)

La differenza dovrebbe essere che il TIFF, il predecessore del RAW, e' il formato, mentre TIF e' l'estensione del file.
Disinstallato subito comunque.

Chiedo scusa ma c'è stato qualche problema con bbcode. Tra le parentesi acute ci stava I dont Know

Semplice ed essenziale programma di steganografia (con google ne trovate anche free) us amolti formati immagini in input, ma in uscita vi lascia salvare solo in png o bmp o tif o tiff (qualacuno mi spiega la differenza tra gli ultimi due :-) ). Usa come algoritmo di modifica il sistema XTGA128 (non so quanto sia solido). Ho provato con un piccolo file testo ed il risultato è stato dignitoso. Ha anche un pulsante inutile. Quando vi chiede la password potete anche selezionare il pulsante "idota" <>, vi lascio immaginare la risposta. L'attivazione è leggermente farraginosa. Dovete avviarlo in modalità demo, poi nell'about c'è la possibilità di registrarlo.
P.S. se per lui il file da inserire risulta troppo grosso, vi chiede di selezionare un'immagine più grande (e dirmi subito quale è il rqapporto ammesso no eh? )
