💖 PEM_WRITE_BIO_CMS_STREAM 💖

okay bestie, so this is the PEM_write_bio_CMS_stream(3ossl) page from the OpenSSL manual, and it's honestly kinda short but it's giving extremely specific niche tool energy and we're obsessed. let's get into it 🎀

✨ NAME ✨

PEM_write_bio_CMS_stream — output CMS_ContentInfo structure in PEM format 🦋

like. that's the whole thing. she does one job and she does it well. periodt.

🌸 SYNOPSIS 🌸

#include <openssl/cms.h>

int PEM_write_bio_CMS_stream(BIO *out, CMS_ContentInfo *cms, BIO *data, int flags);

💅 DESCRIPTION 💅

so PEM_write_bio_CMS_stream() outputs a CMS_ContentInfo structure in PEM format. that's the vibe. 💖

and like, otherwise? it's identical to the function SMIME_write_CMS(). no cap. literally the same behaviour, it's just wearing a different name tag. 🙈

🔥 NOTES 🔥

this function is effectively a version of PEM_write_bio_CMS() that supports streaming. so if you were like "hmm I want the PEM write but make it streaming", congrats, this is her. she ate. 👑

⭐ RETURN VALUES ⭐

  • PEM_write_bio_CMS_stream() returns 1 for success ✨
  • or 0 for failure 💀

that's it. binary. she doesn't do nuance. (ngl a little iconic of her.)

🌈 SEE ALSO 🌈

go read these too, iykyk:

(also lowkey note that the original page lists CMS_decrypt(3) right after CMS_encrypt(3) on the same line — so yeah, they're all one big friend group 🫶)

🧚 HISTORY 🧚

the PEM_write_bio_CMS_stream() function was added in OpenSSL 1.0.0. so she's been around a minute. vintage but not vintage vintage. 💜
