💖 gnutls_pkcs7_get_embedded_data(3) — the gnutls manual, bestie edition 💖

okay so this one lives in the gnutls manual and it's all about digging the embedded data out of a PKCS7 structure. it's giving "treasure hunt but the treasure is bytes" 🎀

---

✨ NAME ✨

gnutls_pkcs7_get_embedded_data — an API function, and yes it does exactly what it says on the tin 🫶

---

🌸 SYNOPSIS 🌸

#include <gnutls/pkcs7.h>

int gnutls_pkcs7_get_embedded_data(gnutls_pkcs7_t pkcs7, unsigned flags,
gnutls_datum_t * data);

---

🦋 ARGUMENTS 🦋

• gnutls_pkcs7_t pkcs7 — this one should contain a gnutls_pkcs7_t type, no cap
• unsigned flags — must be zero or GNUTLS_PKCS7_EDATA_GET_RAW, those are literally the only options bestie
• gnutls_datum_t * data — will hold the embedded data in the provided structure, so it's the lil container that catches everything 💅

---

💜 DESCRIPTION 💜

so this function will return the data embedded in the signature of the PKCS7 structure. main character behaviour fr fr.

if no data are available then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. sad girl hours 😭

the returned data must be de-allocated using gnutls_free(). do NOT forget this — free your stuff, it's self care 🌸

note, that this function returns the exact same data that are authenticated. and if the GNUTLS_PKCS7_EDATA_GET_RAW flag is provided, the returned data will be including the wrapping tag/value as they are encoded in the structure. lowkey important detail, highkey iconic ✨

---

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. zero means slay, negative means go read the error 👑
