So I'm just starting to learn reverse engineering and binary exploitation and going through the RPI course where the first lab set is drawn from the IOLI crackmes available on Github. I could post all of the dissassembly here if it would help.
I'm working on number 5 and I'm confused on one aspect. I understand how to get the solution and get the password ok, but there seems to be a length on the input that I can't trace back to any of the assembly.
The numbers can add up to more than the 10h and the last one can be odd, but once the input is passed 9 characters, it's not accepted.
I'm using gdb and ida and whatever other tools seem helpful, but the specific tools don't matter much to me. Post an explanation with a radare output if you want.
