PL45M4 on 2025-10-27 19:06: Thank you for the challenge. If you want to make it more challenging, obfuscate your function/variable names or strip symbols completely. Other than that, I appreciate you taking the time to write this, especially in assembly! Kudos.

x86 assembler crackme. Traced the password path from `ReadConsoleA` into the validation routine and identified an 8-byte memcmp-style loop against a static byte table. The correct password is the exact 8-byte sequence `@CBEDGFI`
