                               const unsigned char *key, size_t keylen);

🦋 DESCRIPTION 🦋

okay so CMS_EncryptedData_set1_key()</p> rolls up to a cms EncryptedData object and sets the appropriate attributes over to ciph — like, it literally hands the whole vibe over to that cipher. and then 💅 it makes a copy of the symmetric key of size keylen, so your key is safe, she's got her own little duplicate, no sharing, no cap.

🚨 IMPORTANT GIRLIE WARNING 🚨 — AEAD cipher algorithms are not supported. like, at all. do not come for her with an AEAD, she will not answer the phone. 💀

🌸 RETURN VALUES 🌸

  • 0 — something went wrong, an error occurred, we're crying 😭
  • 1 — slay!! everything worked, no error, we ate 👑

so basically it returns 0 if an error occurred, otherwise it returns 1. that's the whole thing. periodt. ✨
