OpenPuff 4.00 - Yet not another steganography SW

  OpenPuff / Source Page  

Portuguese introduction by users & Internet reviews. Thanks!

OpenPuff é uma ferramenta profissional para a esteganografia:
  • HW gerador de números aleatórios (CSPRNG)
  • Esteganografia negável
  • Cadeia de transportadoras (até 256MB de dados ocultos)
  • Seleção do nível de bits das transportadoras
  • Moderna Multi-Criptografia (16 algoritmos)
  • Níveis de ofuscação de dados ocultos (3 senhas)
  • Resistência à esteganalisis X-quadrado (de primeira ordem)

Níveis de segurança e ofuscação unicos:
  • Criptografia de chave simétrica 256+256 bits com extensão de senha KDF4
  • Scrambling dos dados a chave simétrica de 256 bits (mistura em base CSPRNG)
  • Whitening dos dados (mistura com ruído branco em base CSPRNG)
  • Codificação de bits das transportadoras adaptável e não-linear

 

OpenPuff suporta vários formatos de transportadoras:
  • Arquivos de imagem (BMP, JPG, PCX, PNG, TGA)
  • Arquivos de áudio (AIFF, MP3, NEXT/SUN, WAV)
  • Arquivos de vídeo (3GP, MP4, MPG, VOB)
  • Arquivos de Flash-Adobe (FLV, SWF, PDF)

OpenPuff é um software portátil/oculto:
  • Estrutura portátil nativa (sem instalação, sem chaves de registro e arquivos .ini)
  • Compatível com a prevenção de execução de dados (DEP on)
  • Suporte multi-processo (multithread, até 16 CPUs) = processamento mais rápido

OpenPuff é freeware!
  • Livre de spyware / adware
  • Totalmente redistribuível
  • Cripto-biblioteca principal de Criptografia em código aberto (libObfuscate)

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.
