I took me way too long, mainly because I was using wrong disasm tool (cutter). With IDA it was immediately solved.
i can't crack this.. disassembled .. found the variable that it's comparing to, converted from hex to dec but it doesn't seem to work.
My Ghidra didn't display the value, so I had to use gdb to solve this.
after solving a lot of kcbowhunter re challenges this one was a piece of cake xd

Well, maybe easy for someone who knows what they are doing, but for someone starting from 0, this is great place to learn, even if I start from basics and do it in dumb way (ni and info).

For this challenge, I motivated myself to use ghidra for the first time.
Conclusion: the decompiler makes this easy. :)
I'm using Ghidra. Noticed the valid variable being used, but can't find it's value. Help?
