STRUCT SECSPEC(9)

💖 NAME 💖

okay bestie, meet struct secspec — the security specification for SAP commands 🛡️✨. This is the Kernel API Manual page for struct secspec(9), and it’s literally giving “small struct, big main-character energy” 💅.

✨ SYNOPSIS ✨

struct secspec {
    u8 security_level;
    u8 key_id_mode;
    u8 key_source[8];
    u8 key_index;
 };

🎀 Members 🎀

• security_level — 0-7, controls level of authentication & encryption. the auth-and-encrypt dial, bestie 🔐
• key_id_mode — 0-3, specifies how to obtain key. this is the “how do we get the key” setting 🗝️
• key_source — extended key retrieval data. extra key-hunting info goes here 🧚
• key_index — single-byte key identifier. one lil byte to point at the key 🎀
