By reverse-engineering Version 1’s output, modders could deduce the header structure: a 32-byte signature, a table of hashed filenames (often CRC-32), and then the scrambled data blocks. The maker tool’s simplicity was its greatest flaw; because Version 1 did not use per-file encryption keys, once a single key was recovered from the executable, all archives created by CPFM1 were permanently compromised. This led to a cat-and-mouse game where developers would later upgrade to Version 2 or 3, adding AES-128 encryption, leaving Version 1 as a "legacy weak link."
