💖 PKCS12_SAFEBAG_GET0_ATTRS 💖

okay bestie, so this is a page from the OpenSSL manual, section 3SSL, and it's literally about pulling attributes out of a PKCS#12 safeBag. no cap, it's shorter than you think. let's go 🦋

✨ NAME ✨

PKCS12_SAFEBAG_get0_attrs, PKCS12_get_attr_gen — retrieve attributes from a PKCS#12 safeBag 👑

🌸 SYNOPSIS 🌸

#include <openssl/pkcs12.h>

const STACK_OF(X509_ATTRIBUTE) *PKCS12_SAFEBAG_get0_attrs(const PKCS12_SAFEBAG *bag);

const ASN1_TYPE *PKCS12_get_attr_gen(const STACK_OF(X509_ATTRIBUTE) *attrs,
                                     int attr_nid);

💅 DESCRIPTION 💅

so there's two functions here and they do two different little jobs, okay?

PKCS12_SAFEBAG_get0_attrs() retrieves the stack of X509_ATTRIBUTEs from a PKCS#12 safeBag. and like, bag is the PKCS12_SAFEBAG you're pulling the attributes out of. that's it, that's the whole vibe.

PKCS12_get_attr_gen() retrieves an attribute by NID from a stack of X509_ATTRIBUTEs. and attr_nid is the NID of the attribute you want. very "tell me exactly which one and i'll go get it" energy. ✨

🫶 RETURN VALUES 🫶

PKCS12_SAFEBAG_get0_attrs() returns the stack of X509_ATTRIBUTEs from a PKCS#12 safeBag — and lowkey it could be empty. so don't be shocked if you get nothing back.

PKCS12_get_attr_gen() returns an ASN1_TYPE object containing the attribute, or NULL if the attribute was either not present or an error occurred. either way, NULL, bestie 😭

and this is the important part: PKCS12_get_attr_gen() does not allocate a new attribute. the returned attribute is still owned by the PKCS12_SAFEBAG in which it resides. so do NOT go freeing it yourself, it's not yours, it never was 🚫
