💖 CMS_SIGN_RECEIPT — the OpenSSL girlies' guide 💖

okay so this is a page from the OpenSSL manual, section 3SSL, and it's about CMS_sign_receipt. no cap, it's lowkey the receipt-printing queen of the CMS world. let's get into it bestie 🫶

✨ NAME ✨

CMS_sign_receipt — create a CMS signed receipt 📝💅

🌸 SYNOPSIS 🌸

#include <openssl/cms.h>

CMS_ContentInfo *CMS_sign_receipt(CMS_SignerInfo *si, X509 *signcert,
                                  EVP_PKEY *pkey, const STACK_OF(X509) *certs,
                                  unsigned int flags);

🦋 DESCRIPTION 🦋

so CMS_sign_receipt() creates and returns a CMS signed receipt structure. that's the whole gig. iconic. 👑

here's the vibe check on the args:

  • si — this is the CMS_SignerInfo structure holding the signed receipt request. it's giving "here's what you asked me to sign" energy.
  • signcert — the certificate you're signing with 🎀
  • pkey — the corresponding private key, obvs. they're a package deal, iykyk.
  • certs — an optional extra set of certificates to include in the CMS structure. think intermediate CAs in the chain, like the supporting cast. 🌈
  • flags — an optional set of flags. yeah, we'll talk about which ones.

💀 NOTES 💀

okay so this function behaves in a similar way to CMS_sign()... except (and this is the important part, bestie, don't skip it 🙈) these flag values are NOT supported:

  • CMS_DETACHED
  • CMS_BINARY
  • CMS_NOATTR
  • CMS_TEXT
  • CMS_STREAM

why? because they literally do not make sense in the context of signed receipts. it's giving "wrong room, wrong party". they just don't belong. periodt. ✋

👑 RETURN VALUES 👑

CMS_sign_receipt() returns either:

  • a valid CMS_ContentInfo structure ✨ (slay), or
  • NULL if an error occurred 😭

and if you got the NULL, you can snag the error info from ERR_get_error(3). go get your diagnostics, girlie.
