💅 crypto_akcipher_set_pub_key(9) — the Kernel API Manual glow-up

okay so bestie, welcome to the <pink>Kernel API Manual</pink> ✨ this one's called crypto_akcipher_set_pub_key and it's literally the "here's my public key, please take it" of the crypto world 🫶

💖 NAME 💖

crypto_akcipher_set_pub_key — the function that invokes the set public key operation, no cap 🔑

✨ SYNOPSIS ✨

int crypto_akcipher_set_pub_key (struct crypto_akcipher *tfm , const
void *key , unsigned int keylen );

that's the whole signature, character for character, don't @ me 💅

🎀 ARGUMENTS 🎀

  • tfm — your tfm handle. the main character of this whole operation fr fr 🌟
  • key — the BER encoded public key, plus the algo OID, plus paramlen, plus BER encoded parameters. yeah it's a whole little package deal 📦
  • keylen — the length of the key, and not including the other data. just the key, bestie 🙈

🦋 DESCRIPTION 🦋

so what does this actually do? it invokes the algorithm-specific set key function — the one that actually knows how to decode and interpret the encoded key and the parameters 🧚✨

like, this function is the vibe check that hands things off to the algo that speaks the language. iykyk 💜

🔥 RETURN 🔥

  • zero on success 🎉 slay
  • an error code in case of error 😭
