X509_NAME_GET0_DER(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 X509_NAME_GET0_DER 💅

okay so bestie, welcome to the X509_NAME_GET0_DER(3ossl) page — yes that's the OpenSSL manual, section 3, and yes we're gonna get through it together 🫶

✨ NAME ✨

X509_NAME_get0_der — get the X509_NAME DER encoding. that's it, that's the whole vibe. no cap. 🎀

🌸 SYNOPSIS 🌸

#include <openssl/x509.h>

int X509_NAME_get0_der(const X509_NAME *nm, const unsigned char **pder,
                       size_t *pderlen);

like, look at that signature. so clean. obsessed. ✨

🦋 DESCRIPTION 🦋

so here's the tea, bestie ☕ — X509_NAME_get0_der() hands you an internal pointer to the encoding of an X509_NAME structure. it drops that pointer into *pder, and the encoding is *pderlen bytes long. periodt. 💅

and why do you care? because it's literally made for applications that want to examine the encoding of an X509_NAME structure without copying it. no malloc, no memcpy, no drama. you're just peeking. main character energy for real 🧚

you pass in nm (the X509_NAME you're curious about), and out come pder and pderlen doing their little pointer-and-length duet. 🌈

heads up queen: it's an internal pointer. that's the whole point of the function — but internal pointers belong to the object, so keep that in mind, iykyk 👑

💖 RETURN VALUES 💖

  • 1 — slay. success. it worked. 🎉
  • 0 — an error occurred. not slay. 😭

that's the entire return value buffet, bestie. 1 or 0. binary icon behavior. ⭐
