💖 KCAPI_MD_FINAL(3) 💖

okay so bestie, welcome to the page for kcapi_md_final — it lives in the Programming Interface part of the manual, and it's literally the glow-up moment for your message digest. 🦋

✨ NAME ✨

kcapi_md_final — the message digest finalization function (stream version, iykyk). 🎀

✨ SYNOPSIS ✨

ssize_t kcapi_md_final(struct kcapi_handle * handle, uint8_t * buffer,
                       size_t len);

✨ ARGUMENTS ✨

  • handle — [in] the cipher handle, your main character. 👑
  • buffer — [out] gets filled with the message digest. it's giving delivery. 💅
  • len — [in] how long that buffer is, fr fr.

✨ DESCRIPTION ✨

so on success it returns the size of the message digest. slay. 🌟

but if things go sideways:

  • -EIO — the data cannot be obtained. 😭
  • -ENOMEM — the buffer is too small for the complete message digest, and heads up: the buffer is filled with the truncated message digest. not the whole vibe, just a piece of it. 💀
