Just installed the RPM and extraction worked normally, but there are a couple of commandline errors:

@rickhg12hs this is not an error. As OpenStego now supports 2 algos (RandomLSB for data hiding, and Dugad for Watermarking), you need to provide algorithm for which you want read or write formats. For example:

openstego readformats -a RandomLSB

Ah, I didn't see that specifying the algorithm was required. I thought it would list the formats for each algorithm without specifying them.
