Question :
I believe a flag is hidden in this encoding. Can you find it?:

Fine , First thing to observe is "==" in the message ..Its a base-64 encoding is what can be concluded..
Base-64 online tool
we get :
Maybe you should think the other way: [)"}rgheo_hg_gr{tnys" :rfnperjby av tnys rug gbt hbL /b\ !rpvA( :?ti tfihs neve uoy nac ,raen si dnE nA]
After reversing we get :
An End is near, can you even shift it?: (Avpr! \\b/ Lbh tbg gur synt va ybjrepnfr: "synt{rg_gh_oehgr}")
After shifting 13 times that is 'M' is the key..
we get :
Na raq vf arne, pna lbh rira fuvsg vg? : )Nice! \o/ You got the flag lowercase: "flag{et_tu_brute}")]
Flag : et_tu_brute

Thank you, Sir, for taking the time to share the knowledge. Your way of explaining the topic is quite simple and understanding. Here is a website, I would like to suggesthttps://url-decode.com/tool/base64-decode. Actually, that website contains the tools related to decoding and encoding (URL, base64), number utilities, unit converter, developers, string utilities, converter, and IP tools under one domain. So, it will definitely help you out in your future projects.
