STRUCT CRYPTO_AKCIPHER(9)

💅 struct crypto_akcipher(9) 💅

okay bestie, welcome to the struct crypto_akcipher(9) page from the Kernel API Manual ✨ this is literally the glow-up blueprint for user-instantiated objects which encapsulate algorithms and core processing logic. no cap, that’s the whole vibe: you get objects made by the user that wrap up algorithms plus the core processing logic. iconic. 🎀

💖 NAME 💖

struct crypto_akcipher — user-instantiated objects which encapsulate algorithms and core processing logic. periodt. 💅

✨ SYNOPSIS ✨

struct crypto_akcipher {
    unsigned int reqsize;
    struct crypto_tfm base;
};

🌸 Members 🌸

• reqsize — request context size required by algorithm implementation. it’s the size the algorithm implementation needs for its request context, fr fr 🫶
• base — common crypto API algorithm data structure. the shared crypto API foundation, lowkey the main character energy under it all 👑
