crypto_skcipher_encrypt(9)

💅 crypto_skcipher_encrypt — bestie, we're ENCRYPTING

okay so this is a page straight out of the Kernel API Manual (yes, kernel docs can be cute, we contain multitudes) and it's about crypto_skcipher_encrypt. it does exactly what it says on the tin: encrypts plaintext. that's it. that's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

int crypto_skcipher_encrypt (struct skcipher_request *req );

literally one function, one pointer, one int coming back at you. we love a minimal icon. 🎀

---

🦋 ARGUMENTS 🦋

• req — a reference to the skcipher_request handle that holds all the info needed to actually perform the cipher operation. it's giving "everything you need is in the bag already" energy. 👜

---

💖 DESCRIPTION 💖

so here's the tea: this function encrypts plaintext data using that skcipher_request handle. 🔥

and if you're sitting there like "ok but how do i even fill that thing with data??" — no worries bestie, that whole situation is discussed with the skcipher_request_* functions. go read those, they're the main characters of that particular storyline. 📖✨

---

👑 RETURN 👑

• 0 — slay, the cipher operation was successful 💅
• < 0 — nope, an error occurred 😭 (negative number = the vibe check failed)

friendly reminder bestie: the _skcipher and _lskcipher families are two different friend groups and you should not mix them up just because they hang out in the same header file. 💀

and that's the whole page!! 🫶 this lil gem lives in ./include/crypto, dated October 2026, and it's part of the Kernel API Manual — go forth and encrypt responsibly, mwah 💜🧚‍♀️
