STRUCT AUTH_KEYS(9)

✨ NAME ✨

okay so bestie, this is struct auth_keys(9) — the Authentication keys struct — straight out of the Kernel API Manual, section 9 (yes, the (9) is the manual section, iykyk). It’s giving low-level kernel crypto struct realness, and we’re gonna get into it. 💖

🦋 SYNOPSIS 🦋

Here’s the exact shape, no cap:

       struct auth_keys {
           union {
             u8 ipad[64];
             u8 key2[64];
           } u;
           u8 opad[64];
        };

💅 Members 💅

The page only calls out one member, and honestly it’s kind of iconic:

• opad — OPAD or AUTH KEY if auth_input_type = 1.

That’s the whole member note, periodt. 💅

🌈 SEE ALSO 🌈

First up, it points at Kernel file ./drivers/crypto/cavium/nitrox/nitrox_req.h, then the whole squad:

ngl bestie, that’s a lot of crypto friends. Go read them if you want the full lore. 🔥
