`LSB` plugin not available from RPM? #46

Closed rickhg12hs closed 2 years ago

rickhg12hs commented 2 years ago

I see the LSB plugin in the source, but it doesn't seem to be available from the RPM install. Is this intended/expected?

$ openstego algorithms
RandomLSB (Purpose: Data Hiding) - Image based steganography plugin using Random Least Significant Bit algorithm
DWTDugad (Purpose: Watermarking) - Digital watermarking plugin using DWT (Discrete Wavelet Transforms) based on algorithm by Dugad

Yes, this is intentional. LSB was removed long time back as it is very easy to detect. RandomLSB ensures that data gets pseudo-randomly distributed across the cover image, and is harder to detect.

I understand. Was going to use simple LSB algorithm as an easily discovered/decoded example of steganography for newbies.

Looks like I can add it by creating file OpenStegoPlugins.external with contents com.openstego.desktop.plugin.lsb.LSBPlugin and then update the contents of openstego.jar.
