libnvmf_gen_kxchap_key(9)

📦 version 3.2, in arch rolling

💖 libnvmf_gen_kxchap_key(9) — like, the KX-HMAC-CHAP key generator, bestie 💖

okay so real talk, this one lives in the libnvme API manual (yes, the whole libnvme crew 🫶), and it's a function page for libnvmf_gen_kxchap_key. It's giving "crypto key vending machine" energy and honestly? iconic. ✨

✨ NAME ✨

libnvmf_gen_kxchap_key — KX-HMAC-CHAP key generation, periodt 💅

🌸 SYNOPSIS 🌸

int libnvmf_gen_kxchap_key (struct libnvme_global_ctx *ctx , char *hostnqn , enum libnvmf_hmac_alg hmac , unsigned int key_len , unsigned char *secret , unsigned char *key );

bestie, that's a whole lot of arguments and every single one of them matters, so let's go 🧚

🎀 ARGUMENTS 🎀

  • ctx — a struct libnvme_global_ctx object. it's the context babe, it holds the vibe 🌈
  • hostnqn — the Host NVMe Qualified Name. yes, the whole name, not just "host" 🙈
  • hmac — the HMAC algorithm, typed as an enum libnvme_hmac_alg. pick your fighter ⭐
  • key_len — Output key length. it's an unsigned int, so like, be normal about it 💀
  • secret — the Secret to used for digest (their words, not mine, but fr fr that's the secret going into the digest 🔥). it's an unsigned char *
  • key — the Generated KX-HMAC-CHAP key. this is where the magic lands 👑 also unsigned char *
lowkey important: secret comes in, key comes out. don't mix them up bestie, that's not the vibe 😭

💜 RETURN 💜

okay so the glow-up report: if key generation was successful the function returns 0. otherwise? a negative error code. so like, 0 = slay, negative = something went sideways and you gotta deal with it 🦋

🌟 the cute sign-off 🌟

this lil' page is from the libnvmf_gen_kxchap_key section of the libnvme API manual, dated October 2026 — mwah, no cap, go generate some keys responsibly 💖🎀🫶
