akcipher_request_set_crypt(9)

🌸 akcipher_request_set_crypt(9) 🌸

okay bestie so this is a page from the Kernel API Manual and it's genuinely so useful — it's the little setup step that makes your public key crypto request actually know what it's encrypting and where the results go 💅

---

💖 NAME 💖

akcipher_request_set_crypt — sets request parameters ✨

---

🎀 SYNOPSIS 🎀

void akcipher_request_set_crypt (struct akcipher_request *req , struct
scatterlist *src , struct scatterlist *dst , unsigned int src_len ,
unsigned int dst_len );

---

🦋 ARGUMENTS 🦋

• req — your public key request, the main character of this whole story 👑
• src — ptr to input scatter list (the data going in, bestie) 🍓
• dst — ptr to output scatter list (where the results come out) 💫
• src_len — size of the src input scatter list to be processed 📏
• dst_len — size of the dst output scatter list 📐

---

🌈 DESCRIPTION 🌈

Sets the parameters required by the crypto operation ✨ like genuinely this is the function that tells your request "here's the input, here's the output, here's how much of each" and then the operation can actually do its thing 💜

no cap, it's giving setup-step energy — small function, huge responsibilities 🫶

💀 reminder bestie: src_len is the size of the src list and dst_len is the size of the dst list — don't mix them up, iykyk 🙈
