iSteg für Mac

Hi there this is a message for the developer or anyone really, I am downloading isteg onto a Mac Desktop, OS Big Sur version 11.6.6, it says the developer “iSteg” needs to be updated. The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information. Here is the contact message, please respond when you see this please

Open source. Based on outguess 0.2 (not 2.0). Works as advertised.

hi very nice app, thanks.. but i dont know anything about the developer.. who are they.. ? are they harvesting all the txt files i choose to encript and the passwords i use.?

Just tried it out (ver. 1.6.2) and it works as advertised (on OS 10.6.8). Was able to read the decrypted output text file. One thing I did was make sure that I deleted the source text file input bar before changing to decoding as that looked like it could otherwise potentially be a problem. Also like the fact that documentation comes with the application and is accessible directly via the GUI. Two thumbs up for this, Developer. One slight improvement would be for the application to accept jpeg files with the ".jpeg" extension (as is only accepts files with the ".jpg" extension) -- a very small issue, to be sure. FTR, it appears that the MU description has a typo: the developer's site says it is a front end for Outguess 2.0 (not 0.2).

I went through the process to imbed a short message into a jpg photo and produced an output jpg file which I was able to open and all looked great. When I decoded it I produced a '.txt' file but was not able to open it I received the message " The document “output.txt” could not be opened. The file isn’t in the correct format. The file might be corrupted, truncated, or in an unexpected format. " Any idea what I am doing wrong?
