PKCS12_ADD_LOCALKEYID(3ossl)

💖 PKCS12_ADD_LOCALKEYID 💖

okay so this is the 3ossl manpage for PKCS12_add_localkeyid, one of those tiny OpenSSL helpers that does exactly one thing and does it slay. bestie, it's a PKCS#12 function, from openssl/pkcs12.h, and it's genuinely short — we're in and out, no cap. 🎀

🌸 NAME 🌸

PKCS12_add_localkeyid — adds the localKeyId attribute to a PKCS#12 safeBag. that's it. that's the whole job. iconic behavior honestly. ✨

---

🦋 SYNOPSIS 🦋

#include <openssl/pkcs12.h>

int PKCS12_add_localkeyid(PKCS12_SAFEBAG *bag, const char *name,
                          int namelen);

literally three things go in: the bag, a name, and a namelen. int in, int out. we love a clean signature. 💅

---

🌈 DESCRIPTION 🌈

okay so here's the vibe: PKCS12_add_localkeyid() adds an octet string representation of the PKCS#9 localKeyId attribute to a PKCS#12 safeBag. yes, octet string representation — that's the exact wording, i'm not paraphrasing that one because it's doing heavy lifting, iykyk. 🔥

• bag — the PKCS12_SAFEBAG you're adding the attribute to. this is the one the manpage actually explains, so it's the main character here. 👑

the signature also carries name and namelen (both in the synopsis above, character for character, don't come for me) — that's the full parameter list, periodt. 🫶

bestie note: the docs here are short and sweet, so don't go reading extra behavior into it that isn't written down. if it's not on this page, it's not on this page. 🙈

---

⭐ RETURN VALUES ⭐

• returns 1 for success 🎉
• returns 0 for failure 😭

that's the whole spectrum. binary queen. 💀

🧚 SEE ALSO 🧚

• PKCS12_add_friendlyname_asc(3) — go read that one next, it's the sibling vibe. 🌸
