It is not a difficult one, just need to pay attention.

Command-line crackme that hides both its console strings and password check behind a simple XOR-0x9F encoding layer. Using CFF Explorer and Detect It Easy (DIE) for static recon plus x64dbg breakpoints on WriteFile/ReadFile, I traced the input path to a 9-character length check and a character-by-character comparison against an XOR-decoded constant. By NOP-ing the failure branch and single-stepping the comparison loop, I recovered the cleartext password MYPASS123 and confirmed the same XOR-0x9F scheme is used to decode the “Hello World!”, “Enter password:” and “Access Granted/Denied!” strings at runtime.
