💖 PBMAC1_get1_pbkdf2_param — the OpenSSL 3SSL girlies' guide 💖

okay so bestie, welcome to the PBMAC1_GET1_PBKDF2_PARAM(3SSL) page 🎀 this is a little OpenSSL 3SSL manpage and it's genuinely so niche and so cute, like it's giving "I know exactly one thing and I know it perfectly" energy. sit down, grab a boba, let's talk PBKDF2 params extracted out of a PBMAC1 MAC structure 🦋

✨ NAME ✨

PBMAC1_get1_pbkdf2_param — the function that manipulates a PBMAC1 MAC structure 💅 no cap, that's literally its whole job description and it is thriving.

✨ SYNOPSIS ✨

#include <openssl/x509.h>

PBKDF2PARAM *PBMAC1_get1_pbkdf2_param(const X509_ALGOR *macalg);

look at her 🫶 one include, one function, zero drama.

✨ DESCRIPTION ✨

so PBMAC1_get1_pbkdf2_param() goes and retrieves a PBKDF2PARAM structure from an X509_ALGOR structure. that's it. that's the whole vibe. she takes your X509_ALGOR and hands you back the PBKDF2PARAM hiding inside it, like reaching into your bag and pulling out the lip gloss you forgot you packed 🌸

✨ RETURN VALUES ✨

here's the tea ☕ and it's an important one:

  • she returns NULL when PBMAC1 is using an algorithm that is not PBKDF2, or when you passed her incorrect parameters 😭
  • otherwise she returns a pointer to a PBKDF2PARAM structure — slay ✨
bestie, check your return value. NULL is not a personality, it's an error. 🙈

✨ CONFORMING TO ✨

IETF RFC 9579 (https://tools.ietf.org/html/rfc9579) — yes she's standards-compliant, she's an icon, she's a legend and she IS the moment 👑

✨ SEE ALSO ✨

✨ HISTORY ✨

the PBMAC1_get1_pbkdf2_param function was added in OpenSSL 3.4 🎉 so if your OpenSSL is older than that, this function does not exist and you will simply not be having a good time. upgrade era only. ⭐
