STRUCT SA_CMDL_CFG(9)

✨ struct sa_cmdl_cfg(9) ✨

okay so bestie, welcome to the Kernel API Manual page for struct sa_cmdl_cfg — literally the command label configuration descriptor and honestly? it's giving "small struct, big job" energy 🎀

---

🌸 NAME 🌸

struct sa_cmdl_cfg — the Command label configuration descriptor. yeah. that's the whole vibe. it's the little descriptor that holds all your command-label config goodness 💅

---

🦋 SYNOPSIS 🦋

struct sa_cmdl_cfg {
    int aalg;
    u8 enc_eng_id;
    u8 auth_eng_id;
    u8 iv_size;
    const u8 *akey;
    u16 akey_len;
    bool enc;
 };

like, that's the whole thing. seven members, zero drama, all business ✨

---

💖 Members 💖

okay so let's go through the squad one by one, no cap:

• aalg — the authentication algorithm ID. that's it, that's the member, it just tells you which auth algo we're talking about 🔥
• enc_eng_id — the Encryption Engine ID supported by the SA hardware. it's a u8 btw, so keep it cozy 👑
• auth_eng_id — the Authentication Engine ID. sibling energy to enc_eng_id, but for auth 🫶
• iv_size — the Initialization Vector size. how big is the IV? this member knows 🌈
• akey — the Authentication key. note it's a const u8 *, so nobody's mutating it on your watch, periodt 💀
• akey_len — the Authentication key length. it's a u16, and yes it pairs with akey like they're matching bracelets 🎀
• enc — a bool that's True, if this is an encode request. literally just true-or-false, main character energy ⭐

ngl bestie, if you're poking at the SA command label config, you're already deep in the crypto driver trenches. iykyk 💜
