🎀 SYNOPSIS 🎀

int crypto_sig_set_pubkey (struct crypto_sig *tfm , const void *key ,
       unsigned int keylen );

---

🦋 ARGUMENTS 🦋

• tfm — tfm handle. literally the handle, bestie 🫶
• key — BER encoded public key, algo OID, paramlen, BER encoded parameters. yes, all of that is in there 💅
• keylen — length of the key (not including other data). so just the key length, no extra bits counted 🔥

---

🌸 DESCRIPTION 🌸

This function invokes the algorithm specific set key function, which knows how to decode and interpret the encoded key and parameters. it's giving "the algorithm handles the decoding details" energy 🧚
