💖 crypto_alloc_akcipher(9) — Kernel API Manual 💖

okay so bestie, welcome to the crypto_alloc_akcipher(9) page, it's literally the glow-up tutorial for getting yourself a public key algorithm handle ✨

🎀 NAME 🎀

crypto_alloc_akcipher — allocate an AKCIPHER tfm handle, no cap 💅

✨ SYNOPSIS ✨

struct crypto_akcipher * crypto_alloc_akcipher (const char *alg_name ,
u32 type , u32 mask );

like, that's the whole vibe. three args, one iconic return type 🫶

🌸 ARGUMENTS 🌸

  • alg_name — this is the cra_name / name or the cra_driver_name / driver name of the public key algorithm, e.g. "rsa" 🔑 (yes bestie, the classic)
  • type — specifies the type of the algorithm, it's giving "what kind of girlie are we dealing with" 💁‍♀️
  • mask — specifies the mask for the algorithm, the lil filter that goes with type 🎀

🦋 DESCRIPTION 🦋

So what this does is allocate a handle for a public key algorithm. The returned struct crypto_akcipher is the handle that is required for any subsequent API invocation for the public key operations — like, you literally cannot do the later calls without it, it's main character energy 👑

💅 RETURN 💅

  • allocated handle in case of success 🎉
  • IS_ERR is true in case of an error, and PTR_ERR returns the error code 😭 (check it, bestie, don't just rawdog the pointer)

🔥 SEE ALSO 🔥
