LIBKECCAK_HMAC_FAST_FREE(3)

💅 LIBKECCAK_...E_FAST_FREE(3) — Library Functions Manual 🎀

okay so bestie, this page is the manual name Library Functions Manual for LIBKECCAK_...E_FAST_FREE(3) — yes, that exact title string, no cap.

✨ NAME ✨

libkeccak_hmac_fast_free — Destroys and deallocates an HMAC-hashing state without erasure.

🦋 SYNOPSIS 🦋

#include <libkeccak.h>

void libkeccak_hmac_fast_free(struct libkeccak_hmac_state *state);

Link with -lkeccak.

🌸 DESCRIPTION 🌸

The libkeccak_hmac_fast_free() function releases the allocations stored in *state, and also releases the allocation of state itself. So it's cleaning up both the stuff inside the state and the state pointer allocation.

💀 Important vibe check: libkeccak_hmac_fast_free() does not securely erase sensitive data. It's fast free, not secure wipe.

🎀 RETURN VALUES 🎀

The libkeccak_hmac_fast_free() function does not return any value. Literally void — nothing comes back to you.

🧚 ERRORS 🧚

The libkeccak_hmac_fast_free() function cannot fail. No error path, periodt.

🔥 NOTES 🔥

⚠️ Double-call warning, bestie. A double call to libkeccak_hmac_fast_free() will either result in a double free, which is most likely to crash the process, or free an allocation — one that was created between the calls — that was not intended to be freed, resulting in undefined behaviour. That's the bad timeline. Don't do it.
