okay so bestie, welcome to this OpenSSL manual page for PBMAC1_GET1_PBKDF2_PARAM(3ossl) ✨ it’s section 3ossl, and we’re about to make this function make sense, no cap.

🎀 NAME 🎀

PBMAC1_get1_pbkdf2_param — function to manipulate a PBMAC1 MAC structure 💅

🌸 SYNOPSIS 🌸

#include <openssl/x509.h>

PBKDF2PARAM *PBMAC1_get1_pbkdf2_param(const X509_ALGOR *macalg);

🦋 DESCRIPTION 🦋

okay so PBMAC1_get1_pbkdf2_param() retrieves a PBKDF2PARAM structure from an X509_ALGOR structure. that’s the whole move, bestie — it’s giving “get the param out of the alg” energy 🫶

💖 RETURN VALUES 💖

PBMAC1_get1_pbkdf2_param() returns NULL when PBMAC1 uses an algorithm apart from PBKDF2, or when you pass it incorrect parameters 😭 otherwise it returns a pointer to a PBKDF2PARAM structure. slay.

bestie pls note: NULL is the “nope, not happening” answer here — either the algorithm isn’t PBKDF2 or the parameters are incorrect 💀
