💅 I2D_PKCS7_BIO_STREAM 💅

okay so bestie, welcome to the 3ossl corner of the manual, bestie, where we talk about i2d_PKCS7_bio_stream — the little guy whose whole job is to spit out a PKCS7 structure in BER format. that's it. that's the vibe. ✨

🎀 NAME 🎀

i2d_PKCS7_bio_stream — output PKCS7 structure in BER format. no cap, that's literally the whole assignment. 🦋

🌸 SYNOPSIS 🌸

#include <openssl/pkcs7.h>

int i2d_PKCS7_bio_stream(BIO *out, PKCS7 *p7, BIO *data, int flags);

look at those four arguments living their best life. out, p7, data, flags. iconic lineup, tbh. 👑

💖 DESCRIPTION 💖

okay so i2d_PKCS7_bio_stream() outputs a PKCS7 structure in BER format. that's the whole personality.

other than that? it's literally identical to the function SMIME_write_PKCS7(). same energy, same behavior, no notes. 🫶

⭐ NOTES ⭐

this function is effectively a version of d2i_PKCS7_bio() that supports streaming. yes bestie, that d2i_PKCS7_bio() — the streaming one. iykyk. 🌈

💀 BUGS 💀

so here's the tea: the prefix i2d is arguably wrong, because the function outputs BER format. not DER. BER. the name is lowkey lying to you and honestly? we've all been there. 🙈

bestie please don't come for me, i'm just the messenger. the manpage said it, not me. 💅

🔥 RETURN VALUES 🔥

  • 1 — success, slay, it worked ✨
  • 0 — failure, not slay, something went wrong 😭

that's it. binary queen. no in-between. 🎀

🧚 SEE ALSO 🧚

go read them, bestie, they're all in the group chat too. 🫶
