crypto_skcipher_statesize(9)

🦋 crypto_skcipher_statesize(9) 🦋

okay so this is the Kernel API Manual page for crypto_skcipher_statesize(9), and we're about to make state size make sense. no cap. 💅

🌸 NAME 🌸

crypto_skcipher_statesize — obtain state size. that's the whole assignment, bestie. 🎀

✨ SYNOPSIS ✨

unsigned int crypto_skcipher_statesize (struct crypto_skcipher *tfm );

🫶 ARGUMENTS 🫶

• tfm — cipher handle. yes ma'am, that's the one. 💖

💜 DESCRIPTION 💜

okay so some algorithms literally cannot be chained with the IV alone — that's just the vibe. they carry internal state, and if data is going to be processed incrementally, that state must be replicated. 😭

this function gets you the size of that state. iconic behavior, honestly. ✨

🔥 RETURN 🔥

the state size in bytes. periodt. 💅
