// Simulate a secret key (32 bytes) size_t key_len = 32; unsigned char *key = (unsigned char *)aligned_alloc(16, key_len); if (!key) exit(1);

macOS (Darwin) uses sysctl :

You must verify that sensitive data does not leak. Here is a test harness: dev-antidump

With these, even a full memory dump from a hypervisor reveals nothing without the ephemeral encryption key stored inside the CPU. // Simulate a secret key (32 bytes) size_t

For an attacker who gains minimal access to a server (e.g., via a crash or a debugging interface), a core dump is a goldmine. if (!key) exit(1)
