Detailed Description

Implementation of the platform-independent utility helpers.

CW_Utils::secure_compare iterates over the full length to avoid leaking byte-position information through timing. CW_Utils::secure_wipe uses a volatile pointer so the writes cannot be optimised away. CW_Utils::safe_memcpy validates pointers, length, and source/destination overlap before delegating to memcpy.
