OpenPuff es una herramienta profesional de esteganografía:


  • HW generador de números aleatorios (CSPRNG)

  • Esteganografía negable

  • Cadenas de portadores (hasta 256Mb de datos ocultos)

  • Nivel de selección de bits de portadores

  • Multi-Criptografía moderna (16 algoritmos)

  • Niveles de ofuscación de los datos ocultos (3 contraseñas)

  • Resistencia a la esteganalisis X-Cuadrado (de primer orden)


Capas de seguridad y ofuscación únicas:


  • Criptografía de clave simétrica de 256+256 bits (con extensión de la contraseña KDF4)

  • Scrambling de los datos de clave simetrica de 256 bits (mezcla basada en CSPRNG)

  • Whitening de los datos (mezcla con ruido blanco basada en CSPRNG)

  • Codificación de bits de portadores adaptativa y no lineal

  

OpenPuff soporta muchos formatos de portadores:


  • Archivos de imágen (BMP, JPG, PCX, PNG, TGA)

  • Archivos de video (3GP, MP4, MPG, VOB)

  • Archivos de Flash-Adobe (FLV, SWF, PDF)


OpenPuff es un software potátil/oculto:


  • Estructura portátil nativa (sin instalación, claves de registro, archivos .ini)

  • Compatible con la prevención de ejecución de datos (DEP)

  • Soporte multi-proceso (hasta 16 cpus) = procesamiento más rápido


OpenPuff es freeware:


  • Libre de spyware/adware

  • Completamente redistribuible

  • Cripto-biblioteca principal en Código abierto (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.


  • 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).


  1. 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

  2. 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.

  3. 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.

  4. 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.
