ASN1_ITEM_NEW(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

okay bestie, welcome to ASN1_ITEM_NEW(3ossl) — the OpenSSL manual page for making new ASN.1 values. we’re gonna keep it cute and keep every detail, mkay? 💖

🌸 NAME 🌸

ASN1_item_new_ex, ASN1_item_new — create new ASN.1 values ✨

✨ SYNOPSIS ✨

#include <openssl/asn1.h>

ASN1_VALUE *ASN1_item_new_ex(const ASN1_ITEM *it, OSSL_LIB_CTX *libctx,
                             const char *propq);
ASN1_VALUE *ASN1_item_new(const ASN1_ITEM *it);

💅 DESCRIPTION 💅

okay so ASN1_item_new_ex() creates a brand-new ASN1_VALUE structure based on the ASN1_ITEM template you pass in through the it parameter. If any algorithm fetches are required during the process, they’re gonna use the OSSL_LIB_CTX provided in the libctx parameter and the property query string in propq. for the full tea on algorithm fetching, see "ALGORITHM FETCHING" in crypto(7) — yep, that’s the section to check, iykyk 🫶

ASN1_item_new() is literally the same as ASN1_item_new_ex() except that the default OSSL_LIB_CTX is used (i.e. NULL) and with a NULL property query string. periodt 💅

🌈 RETURN VALUES 🌈

ASN1_item_new_ex() and ASN1_item_new() return a pointer to the newly created ASN1_VALUE, or NULL on error. that’s it, no cap ✨

🦋 HISTORY 🦋

The function ASN1_item_new_ex() was added in OpenSSL 3.0. iconic behavior, honestly 👑
