Easy find key
jirubizu on 8:37 PM 04/08/2023: I won't lie, I don't think this is a 2.0 difficulty as you can simply open this up in something like luyten and see the code key in plain text. 1.0 difficulty seems more appropriate but nice regardless
chris.dinozzi on 11:19 AM 04/14/2023: i agree with jirubizu, it's quite an easy room, but was fun regardless. my first time on the site and my first time reversing a .jar file so i enjoyed it.
Mypowaa on 3:55 PM 05/20/2023: Sorry I never tried this for java and I'm a beginner is the .jar supposed to open or what ?
0xh3xa on 2:37 PM 05/27/2023: @Mypowaa The jar is just an archive method to put all *.classes files together, the way to decompile the byte-code of the *.classes using tools like bytecode-viewer, jadx, etc. https://github.com/skylot/jadx https://github.com/Konloch/bytecode-viewer
