OpenPuff is a professional steganography tool:

HW seeded random number generator (CSPRNG)

Deniable steganography

Carrier chains (up to 256Mb of hidden data)

Carrier bits selection level

Modern multi-cryptography (16 algorithms)

Multi-layered data obfuscation (3 passwords)

X-squared steganalysis resistance

Unique layers of security and obfuscation:

256bit+256bit symmetric-key cryptography (with KDF4 password extension)

256bit symmetric-key data scrambling (CSPRNG-based shuffling)

256bit symmetric-key data whitening (CSPRNG-based noise mixing)

Adaptive non-linear carrier bit encoding

OpenPuff supports many carrier formats:

Images (BMP, JPG, PCX, PNG, TGA)

Audio support (AIFF, MP3, NEXT/SUN, WAV)

Video support (3GP, MP4, MPG, VOB)

Flash-Adobe support (FLV, SWF, PDF)

OpenPuff is a portable/stealth software:

Native portable structure (no installation, registry keys, .ini files)

Runs in user mode with DEP on

Multithread support (up to 32 CPUs) = Faster processing

OpenPuff is safe:

Spyware/adware-free

Fully redistributable

OpenSource core crypto-library (libObfuscate)
