PEM_WRITE_BIO_PKCS7_STREAM(3SSL)

πŸ’– PEM_WRITE_BIO_PKCS7_STREAM(3SSL) πŸ’–

okay bestie, sit down, hydrate, because we're about to talk about PEM_write_bio_PKCS7_stream, a little legend from the OpenSSL manual, section 3SSL. yes it's giving crypto. yes it's iconic. let's get into it 🫢


✨ NAME ✨

PEM_write_bio_PKCS7_stream β€” output PKCS7 structure in PEM format 🌸

like. that's the whole job. it takes your PKCS7 situation and writes it out as PEM. periodt.


πŸŽ€ SYNOPSIS πŸŽ€

#include <openssl/pkcs7.h>

int PEM_write_bio_PKCS7_stream(BIO *out, PKCS7 *p7, BIO *data, int flags);

look at her. four arguments, one int return, zero drama (well, ok, the return value has some drama, we'll get there) πŸ’…


πŸ¦‹ DESCRIPTION πŸ¦‹

PEM_write_bio_PKCS7_stream() outputs a PKCS7 structure in PEM format. that's it, that's the vibe check, it passed βœ…

other than that? it is otherwise identical to the function SMIME_write_PKCS7(). like literally same energy, same behaviour, just a different name on the door. no cap. so if you already know SMIME_write_PKCS7(), you already know her 🧚


πŸ’œ NOTES πŸ’œ

so here's the tea β˜• β€” this function is effectively a version of PEM_write_bio_PKCS7() that supports streaming. that's the whole glow-up. streaming support. main character upgrade. πŸ”₯


πŸ‘‘ RETURN VALUES πŸ‘‘

  • 1 β€” slay πŸ’… success, we ate
  • 0 β€” nope 😭 failure, call ERR_get_error(3) and find out why

one or zero. binary. no in-between, no "sort of worked", no crumbs. 🀷
