Jika kamu tidak ingin file atau dokumen pribadimu dibuka atau dilihat orang lain,
apa yang akan kamu lakukan? Apakah kamu mewinrarnya kemudian kamu beri password untuk
membukanya? Atau kamu menghiddennya? Semua cara yang kamu lakukan itu sudah termasuk
cara yang kuno.
OpenPuff adalah software steganografi yang sangat kuat sehingga memungkinkan kamu
untuk menyembunyikan file atau dokumen rahasiamu dari orang lain.
Software ini bekerja dengan menyembunyikan file rahasiamu ke dalam file lain.
Jadi kamu menyembunyikan file didalam file lain. OpenPuff dapat menyembunyikan file
yang berformat BMP, JPG, PNG, MP3, WAV, MP4, MPG, FLV, SWF, PDF dan masih banyak lagi.
OpenPuff is a professional steganography tool with unique features, suitable for highly sensitive data covert transmission.
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.
Multiple layers of security:
Data, before carrier injection, is encrypted (1), scrambled (2), whitened (3) and encoded (4).
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.

Reference Images for Testing
All images in this section are high-quality, free of DCT artifacts and absolutely free to be used, cited, edited for any academic or software steganography-related development. Provided formats are BMP, JPG, PNG, RAW at 8/8/8 bit RGB color and 8 bit Greyscale, 512x512 and 256x256 resolution. All EXIF and ICC metadata info has been removed, to easily check if a steganography tool is actively adding metadata to a carrier. Artificial, NASA, Natural and Portrait images let you test the performance of a steganography implementation in different scenarios.
[ Difficulty level EXPERT ]
All Artificial + NASA + Natural + Portrait images are available as 512x512 & 256x256 / RGB & MONO
