Data hiding and watermarking made easy, safe and free. Advanced Steganography and Watermarking - Image/Audio/Video/Adobe/Flash support.

OpenPuff is a professional steganography tool
1. HW seeded random number generator (CSPRNG)
2. Deniable steganography
3. Carrier chains (up to 256Mb of hidden data)
4. Carrier bits selection level
5. Modern multi-cryptography (16 algorithms)
6. Multi-layered data obfuscation (3 passwords)
7. X-square steganalysis resistance

Unique layers of security and obfuscation
1. 256bit+256bit symmetric-key cryptography with KDF4 password extension
2. 256bit symmetric-key data scrambling (CSPRNG-based shuffling)
3. Data whitening (CSPRNG-based noise mixing)
4. Adaptive non-linear carrier bit encoding

OpenPuff supports many carrier formats
1. Images (BMP, JPG, PCX, PNG, TGA)
2. Audio support (AIFF, MP3, NEXT/SUN, WAV)
3. Video support (3GP, MP4, MPG, VOB)
4. Flash-Adobe support (FLV, SWF, PDF)

OpenPuff is a portable/stealth software
1. Native portable structure (no installation, registry keys, .ini files)
2. Multithread support (up to 16 cpus) = Faster processing

OpenPuff is freeware
1. Spyware/adware-free
2. Fully redistributable
3. Semi-open-source release, cryptography code available
