KCAPI_MD_DIGESTSIZE(3)

✨ NAME ✨

kcapi_md_digestsize — bestie, this one just tells you how big your message digest is 💖

---

🌸 SYNOPSIS 🌸

uint32_t kcapi_md_digestsize(struct kcapi_handle * handle);

---

🎀 ARGUMENTS 🎀

• handle — [in] the cipher handle, aka your little gateway to the crypto vibes 🦋

---

💅 DESCRIPTION 💅

okay so here's the tea: this function hands you back the size of the message digest. that's it. that's the whole job. ✨

and like, why do you care? because you can call this before you hit up kcapi_md_final — that way you already know exactly how much memory you need to allocate for that call. no guessing, no overflow, no tears. it's giving prepared. it's giving organized. 🫶

what comes back:

• > 0 — slay, that's the block size, use it 🌈
• 0 — on error 😭 something went wrong bestie
