nvme_export_tls_key(2)

✨ NAME ✨

nvme_export_tls_key — ok bestie, this one exports a TLS key 💅 it's from the libnvme API manual, section 2 of the manual pages, and honestly? iconic behaviour.

---

🎀 SYNOPSIS 🎀

char * nvme_export_tls_key (const unsigned char *key_data , int key_len );

She takes two things and gives you back a char *. Simple. Elegant. We love to see it. 🦋

---

🌸 ARGUMENTS 🌸

• key_data — the raw data of the key, literally just the bytes, no glow-up yet 🙈
• key_len — how long key_data is, like a lil measuring tape for your key 📏

---

💖 DESCRIPTION 💖

So what she actually does: she hands you back your key_data, but dressed up all fancy in the PSK Interchange format, exactly as it's defined in section 3.6.1.5 of the NVMe TCP Transport specification. It's giving key... but make it fashion. 💅✨

No cap, that's the whole job. Raw bytes in, pretty spec-compliant string out. Periodt. 👑

---

🔥 RETURN 🔥

On a good day she returns the string containing the TLS identity. 🫶

On a bad day she returns NULL and sets errno to tell you what went wrong. 😭

⚠️ Bestie, listen carefully: it is the responsibility of the caller to free the returned string. She's not gonna clean up after you. That memory is yours now. Free it. Don't ghost it. 🗑️💀
