Features

  • OpenStego is written in pure Java and should run on all platforms supported by java. It has been tested on MS Windows and Linux, but should not have any problem on other platforms too. Please report bugs if you find any.
  • It supports password-based encryption of data for additional layer of security. DES algorithm is used for data encryption, along with MD5 hashing to derive the DES key from the password provided.
  • It uses a plugin based architecture, where various plugins can be created for different kind of Steganographic algorithms. Currently, it supports two plugins - LSB (Using Least Significant Bit of Image Pixels) and RandomLSB (Randomized LSB), but new plugins can be created for other algorithms like DCT, FFT, etc. Plugins can also be easily added for other type of cover files like Audio files.
  • LSB plugins support only 24 bpp images. Support for additional image formats (like BMP, TIF, etc.) could be added by installing Java Advanced Imaging (JAI).
  • LSB plugins also support generation of random images containing noise to be used as cover file. The size of the generated random image is the minimum possible size required to embed the given data.

To Do

  • Add support for other Steganographic algorithms like DCT, FFT, etc.
  • Add support for audio data to be used as cover file.
  • Implement OpenStego in C/C++, so that it can be compiled as native binary, and dependency on Java is removed.
