💅 PKCS7_GET_OCTET_STRING 💅

okay so this is the 3ossl manual page for PKCS7_get_octet_string, bestie ✨

🌸 NAME 🌸

PKCS7_get_octet_string — literally just returns the octet string from a PKCS#7 envelopedData structure 🎀

🦋 SYNOPSIS 🦋

#include <openssl/pkcs7.h>

ASN1_OCTET_STRING *PKCS7_get_octet_string(PKCS7 *p7);

💖 DESCRIPTION 💖

so PKCS7_get_octet_string() hands you back a pointer to an ASN1 octet string, pulled straight out of a PKCS#7 envelopedData structure 🫶

and if the structure can't be parsed? it gives you NULL. no octet string for you, bestie 😭 that's the vibe check and it failed.

✨ NOTES ✨

this is the important part, so listen up 👑

as that 0 in the name implies (iykyk), PKCS7_get_octet_string() returns internal pointers — which means the caller should NOT free them. like, do not touch. do not free(). put your hands down. it's giving "not yours" 🙈

fr fr, freeing these is a whole mess. the library owns them, you're just visiting 💀

🎀 RETURN VALUES 🎀

PKCS7_get_octet_string() returns an ASN1_OCTET_STRING pointer. that's it, that's the return value 🌈 (or NULL if the parsing situation went sideways, as mentioned above ✨)
