OpenPuff 4.00 - Yet not another steganography SW
|
Slovak introduction by users & Internet reviews. Thanks!
Vytváranie, prechovávanie aj posielanie zašifrovaných dát môže už samo o sebe predstavovať riziko odhalenia. Alternatívou je uchovanie v tajnosti aj fakt, že sa snažíte niečo skryť.Je malá, jednoduchá a veľmi účinná aplikácia, ktorá sa zaoberá tzv steganografiov. Jedná sa o spôsob šifrovania informácií, kedy dáta sú skryté do dát iných tak, aby nebolo na pohľad vôbec poznať, že tu sú nejaké informácie ukryté. Jedná sa typicky o zakomponovanie údajov do súborov, fotiek alebo dokumentov, ktoré nevyzerajú podozrivo, keď samy o sebe leží na disku počítača alebo sa posielajú ako príloha e-mailu.OpenPuff dokáže bezpečne a spoľahlivo šifrovať dáta a ľahko vkladať vodotlač do rôznych súborov. |
Na rozdiel od iných podobných programov, ktoré
pracujú len s grafickými súbormi, OpenPuff
ponúka celú škálu výstupných
formátov. Zaradiť sem možno okrem grafiky aj audio, video
a tiež PDF. Ide celkovo o 16 rôznych druhov výstupu.
Podporuje najpoužívanejšie formáty:
OpenPuff je teda zaujímavým pomocníkom aj pre málo skúsených užívateľov, ktorí jeho ovládanie pochopí behom pár minút. Väčšiemu rozšíreniu aplikácie navyše nahráva aj fakt, že je možné ju užívať úplne zadarmo. |

OpenPuff is a professional steganography tool, with unique features you won't find among any other
free or commercial software. OpenPuff is 100% free and suitable for highly sensitive data covert
transmission. Let's take a look at its features
- Carrier chains :
Data is split among many carriers. Only the correct carrier sequence enables unhiding. Moreover,
up to 256Mb can be hidden, if you have enough carriers at disposal. Last carrier will be filled with
random bits in order to make it undistinguishable from others.
- Supported formats :
Images, audios, videos, flash, adobe.
- Layers of security :
Data, before carrier injection, is encrypted (1), scrambled (2), whitened (3) and encoded (4).
- Layer 1 - Modern multi-cryptography :
A set of 16 modern 256bit open-source cryptography algorithms (chosen from
AES Process [1997-2000],
NESSIE Process [2000-2003] and
CRYPTREC Process [2000-2003])
has been joined into a doublepassword multi-cryptography algorithm (256bit+256bit)
: AES
/ Anubis
/ Camellia
/ Cast-256
/ Clefia
/ FROG
/ Hierocrypt3
/ Idea-NXT
/ MARS
/ RC6
/ Safer+
/ SC2000
/ Serpent
/ Speed
/ Twofish
/ Unicorn-A
- Layer 2 - CSPRNG based scrambling :
Encrypted data is always scrambled to break any remaining stream pattern. A new
cryptographically secure pseudo random number generator (CSPRNG) is seeded with a third
password (256bit) and data is globally shuffled with random indexes.
- Layer 3 - CSPRNG based whitening :
Scrambled data is always mixed with a high amount of noise, taken from an independent
CSPRNG seeded with hardware entropy.
- Layer 4 - Adaptive non-linear encoding :
Whitened data is always encoded using a non-linear function that takes also original carrier bits
as input. Modified carriers will need much less change and deceive many steganalysis tests
(e.g.: chi square test).
- Extra security - Deniable steganography :
Top secret data can be protected using less secret data as a decoy.
- Source code :
This program relies on the libObfuscate system-independent open-source library. Users and
developers are absolutely free to link to the core library (100% of the cryptography & obfuscation
code), read it and modify it.
