OpenStego is a simple steganography tool.
It supports password-based encryption of data for additional layer of security.
It’s free and open source software.
Key Features
- Data hiding – hide the data (file) inside an image or extract the data from the image.
- Extract data.
- Watermarking – watermark / verify images with your signature. The digital watermarking code is based on code written by Peter Meerwald.
- Generate your signature.
- Embed the watermark.
- Verify the watermark.
- Supported encryption algorithms: AES128, AES256.
- Uses a plugin based architecture, where various plugins can be created for different kind of Steganographic / Watermarking algorithms. Currently, it supports two plugins – RandomLSB (Randomized LSB) for data hiding and Dugad’s algorithm for watermarking, but new plugins can be easily created for other algorithms. Plugins can also be easily added for other type of cover files like Audio files.
- All functionality is accessible using the command line in addition to the GUI.
