X509_STORE_GET0_PARAM(3ossl)

✨ X509_STORE_GET0_PARAM ✨

okay bestie, pull up a chair, because we're doing the X509_STORE_GET0_PARAM(3ossl) page from the OpenSSL manual and honestly?? it's giving ✨certificate-store-gossip✨. it's all about getting stuff out of an X509_STORE and setting stuff into it. setters, getters, the whole friend group 🫶

🌸 NAME 🌸

X509_STORE_get0_param, X509_STORE_set1_param, X509_STORE_get1_objects, X509_STORE_get0_objects, X509_STORE_get1_all_certs — the X509_STORE setter and getter squad 💅

🎀 SYNOPSIS 🎀

like, here's the whole vibe, verbatim, no notes:

#include <openssl/x509_vfy.h>

X509_VERIFY_PARAM *X509_STORE_get0_param(const X509_STORE *xs);
int X509_STORE_set1_param(X509_STORE *xs, const X509_VERIFY_PARAM *pm);
STACK_OF(X509_OBJECT) *X509_STORE_get1_objects(X509_STORE *xs);
STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(const X509_STORE *xs);
STACK_OF(X509) *X509_STORE_get1_all_certs(X509_STORE *xs);

🦋 DESCRIPTION 🦋

okay so, one by one, main character by main character 👑

• X509_STORE_set1_param() sets the verification parameters to pm for xs. like, "here bestie, these are your rules now" 💖
• X509_STORE_get0_param() retrieves an internal pointer to the verification parameters for xs. and listen — the returned pointer must not be freed by the calling application. it's not yours, don't touch it, hands off 🙈
• X509_STORE_get1_objects() returns a snapshot of all objects in the store's X509 cache. the cache contains X509 and X509_CRL objects. this one is yours though — the caller is responsible for freeing the returned list, using sk_X509_OBJECT_pop_free(sk, X509_OBJECT_free). so like, you got it, you clean it up 🧹
• X509_STORE_get0_objects() retrieves an internal pointer to the store's X509 object cache. the cache contains X509 and X509_CRL objects. the returned pointer must not be freed by the calling application. and here's the tea: if the store is shared across multiple threads, it is not safe to use the result of this function. use X509_STORE_get1_objects() instead, which avoids this problem. thread safety said "not today" 💀
• X509_STORE_get1_all_certs() returns a list of all certificates in the store. the caller is responsible for freeing the returned list with OSSL_STACK_OF_X509_free(). free it bestie, that's the rule 🫶

⭐ RETURN VALUES ⭐

• X509_STORE_get0_param() returns a pointer to an X509_VERIFY_PARAM structure. 🎀
• X509_STORE_set1_param() returns 1 for success and 0 for failure. classic binary slay.
• X509_STORE_get1_objects() returns a pointer to a stack of the retrieved objects on success, else NULL. 😭 when it's NULL it's over fr fr
• X509_STORE_get0_objects() returns a pointer to a stack of X509_OBJECT.
• X509_STORE_get1_all_certs() returns a pointer to a stack of the retrieved certificates on success, else NULL.
