💖 CMS_SIGN_RECEIPT 💖

okay bestie, pull up a chair because we're talking about CMS_sign_receipt(3ossl) — yes that's the whole manual name, it's giving official document energy but we're gonna make it cute. This one lives in the openssl/cms.h cinematic universe and it's here to make you a CMS signed receipt. Slay. 🎀

✨ NAME ✨

CMS_sign_receipt — literally just: create a CMS signed receipt. that's the whole job. iconic. 💅

🌸 SYNOPSIS 🌸

#include <openssl/cms.h>

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

look at her. five arguments. no cap. 🦋

💜 DESCRIPTION 💜

so CMS_sign_receipt() creates and returns a CMS signed receipt structure. that's the main character move right there. ✨

here's who's who in this little friend group:

  • si — the CMS_SignerInfo structure that's holding the signed receipt request. like, the ask itself. 🫶
  • signcert — the certificate you're signing with. your little ID badge. 🎀
  • pkey — the corresponding private key. the matching key to that cert, they're a set, don't separate them. 🔑
  • certs — an optional extra set of certificates to include in the CMS structure. for example, any intermediate CAs in the chain. optional! so you can pass it or not, no judgment. 🌈
  • flags — an optional set of flags. the vibe knobs. ⭐

👑 NOTES 👑

this function behaves in a similar way to CMS_sign() except — and listen closely bestie because this is the important part — these flag values are not supported, because they just don't make sense in the context of signed receipts:

  • CMS_DETACHED
  • CMS_BINARY
  • CMS_NOATTR
  • CMS_TEXT
  • CMS_STREAM

so if you were about to pass one of those, don't. it's not a vibe. 🚫

💀 RETURN VALUES 💀

CMS_sign_receipt() returns either a valid CMS_ContentInfo structure or NULL if an error occurred. 😭

if you got NULL, you can get the error from ERR_get_error(3). go read the receipt of your own mistakes, bestie. 🔥

🦋 SEE ALSO 🦋

the little family. go read them too. iykyk. 💖
