Our Secret!

DeepSound is a steganography tool and audio converter that hides secret data into audio files. The application also enables you to extract secret files directly from audio files or audio CD tracks.

SilentEye is a cross-platform application design for an easy use of steganography, in this case hiding messages into pictures. It provides a pretty nice interface and an easy integration of new steganography algorithm and cryptography process by using a plug-ins system.

OpenPuff is a professional steganography tool:HW seeded random number generator (CSPRNG)Deniable steganographyCarrier chains (up to 256Mb of hidden data)Carrier bits selection levelModern multi-cryptography (16 algorithms)Multi-layered data obfuscation (3 passwords)X-squared steganalysis resistance

Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests.

OpenStego is a tool implemented in Java for generic steganography, with support for password-based encryption of the data. It supports plugins for various steganographic algorithms

iSteg is an encryption tool used to hide a file (for example a zip archive) inside a jpeg picture. This encryption technology is called steganography. iSteg is a frontend for the opensource tool outguess 2.0. iSteg can be used to both encode and decode a hidden file.

Secret Layer lets you encrypt your data and then hide that encrypted data in ordinary images, like the ones used every day on all websites and email attachments. Secret Layer very slightly tweaks the color of specific pixels. You can't distinguish the altered photo from the original one. Any time you transfer an encrypted file to someone by email, Skype, or another method, anyone on your network can see that you're transferring something encrypted. But when you hide your data in a image, to everyone else it looks like you're uploading another photo to the web, just like billions of other people. In other words, yourphoto can slip away in the crowd, no different from everyone else. »

BitCrypt - The Ultra-Strong Encryption that is easy to use

MP3Stego will hide information in MP3 files during the compression process. The data is first compressed, encrypted and then hidden in the MP3 bit stream. Although MP3Stego has been written with steganographic applications in mind it might be used as a copyright marking system for MP3 files (weak but still much better than the MPEG copyright flag defined by the standard). Any opponent can uncompress the bit stream and recompress it; this will delete the hidden information – actually this is the only attack we know yet – but at the expense of severe quality loss. »

Outguess-Rebirth is a portable steganography tool for Windows, allows a user to embed hidden data inside a image JPEG. Outguess-Rebirth is 100% free and suitable for highly sensitive data covert transmission.

QuickStego is a handy, easy to use tool specially designed to help you hide text in pictures so that only other users of QuickStego can retrieve and read the hidden secret messages.
