NVME_GENERATE_TLS_KEY_IDENTITY(2)

✨ NAME ✨

nvme_generate_tls_key_identity — bestie, this is the one that generates the TLS key identity 💅 literally what it says on the tin

---

🌸 SYNOPSIS 🌸

char * nvme_generate_tls_key_identity (const char *hostnqn , const char
*subsysnqn , int version , int hmac , unsigned char *configured_key ,
int key_len );

---

🎀 ARGUMENTS 🎀

• hostnqn — the Host NVMe Qualified Name, aka who you are in this whole situation 🫶
• subsysnqn — the Subsystem NVMe Qualified Name, aka who you're talking to 👑
• version — which key version to use, pick your era babe
• hmac — the HMAC algorithm, the secret sauce selection ✨
• configured_key — the configured key data that we're gonna derive the key from 🔑
• key_len — length of configured_key, like how many bytes of vibe we're working with

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ this function derives a 'retained' TLS key exactly as specified in NVMe TCP, and then it generates the corresponding TLS identity that goes with it. it's giving key derivation, it's giving identity generation, it's giving exactly what you asked for 💖

---

⭐ RETURN ⭐

you get back the string containing the TLS identity. and yes bestie, it is 100% the responsibility of the caller to free the returned string — don't leave that memory hanging, that's not the vibe 🙈

on error, NULL is returned with errno set. no cap.

⚠️ warning babe: NULL + errno set means check it. every single time. do not skip the check, the check is your best friend 🫶
