🧾 NAME 🧾

CMS_sign_receipt — create a CMS signed receipt. Bestie, this is the CMS_SIGN_RECEIPT(3ossl) page from OpenSSL, and we're making signed receipts. No cap. 💅

✨ 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);

🛠️ DESCRIPTION 🛠️

Okay so CMS_sign_receipt() creates and returns a CMS signed receipt structure. It's giving "receipt, but make it signed" and honestly? Iconic. 💖

  • si — the CMS_SignerInfo structure containing the signed receipt request. This is literally the main character of the request, iykyk.
  • signcert — the certificate to sign with. Slay.
  • pkey — the corresponding private key. Guard it with your life, bestie. 🔐
  • certs — an optional additional set of certificates to include in the CMS structure (for example any intermediate CAs in the chain). Lowkey important if you've got a whole chain situation going on.
  • flags — an optional set of flags. Cute little toggles, but read the notes first, fr fr.

⚠️ NOTES ⚠️

This function behaves in a similar way to CMS_sign(), except these flag values are not supported: CMS_DETACHED, CMS_BINARY, CMS_NOATTR, CMS_TEXT, and CMS_STREAM. The way that they do not make sense in the context of signed receipts — periodt. So don't try to force them, bestie; it's not the vibe. 🙈

🔁 RETURN VALUES 🔁

CMS_sign_receipt() returns either a valid CMS_ContentInfo structure or NULL if an error occurred. If you get NULL, it's giving "something went wrong," and you can obtain the error from ERR_get_error(3). Go check it, ngl. 😭
