✨ CMS_final(3) ✨

okay bestie, welcome to the library functions manual 💖 this page is all about CMS_final() and it is literally the finaliser for a CMS_ContentInfo structure. no cap.

🌸 NAME 🌸

CMS_final — finalise a CMS_ContentInfo structure 💅

🎀 SYNOPSIS 🎀

library “libcrypto” #include <openssl/cms.h>

int
CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont,
    unsigned int flags);

🦋 DESCRIPTION 🦋

okay so CMS_final() finalises the structure cms. its whole purpose is to perform any operations necessary on cms — digest computation for example — and set the appropriate fields. ✨

The parameter data contains the content to be processed. 🍓

The dcont parameter contains a BIO to write content to after processing: this is only used with detached data and will usually be set to NULL. 🙈

This function will normally be called when the CMS_PARTIAL flag is used. 🫶

bestie, it should only be used when streaming is not performed because the streaming I/O functions perform finalisation operations internally. like, do not come for streaming here, fr fr 💀

🌈 RETURN VALUES 🌈

CMS_final() returns 1 for success or 0 for failure. that's it. iconic binary behavior 👑

👀 SEE ALSO 👀

💜 HISTORY 💜

CMS_final() first appeared in OpenSSL 0.9.8h and has been available since OpenBSD 6.7. periodt ✨
