OpenStego is a Java-based steganography application that hides data inside image files and embeds invisible watermarks to detect unauthorized copying. It offers both a GUI and a command-line interface, with a plugin architecture for different steganographic algorithms.
Use cases
- hide a secret file inside an image
- extract hidden data from a stego image
- watermark images with an invisible signature
- detect unauthorized copying of images
- encrypt hidden payloads with AES
- embed steganography into another Java project via API
When to choose
- you need free, cross-platform image steganography with a GUI or CLI
- you want to watermark images to prove ownership
- you need a Java API for steganography in your own app
When to avoid
- you need steganography for audio or video cover files
- you need cutting-edge steganographic algorithms like DCT or FFT
- you need actively developed software with frequent updates
