CMS_SIGN_RECEIPT(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 CMS_sign_receipt 💖

okay bestie, welcome to the 3ossl manual page for CMS_sign_receipt — it's giving “create a CMS signed receipt” main character energy ✨

🎀 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, STACK_OF(X509) *certs,
                                          unsigned int flags);

🌸 DESCRIPTION 🌸

okay so CMS_sign_receipt() creates and returns a CMS signed receipt structure. No cap, that’s the whole vibe 💅

  • si is the CMS_SignerInfo structure containing the signed receipt request.
  • signcert is the certificate to sign with.
  • pkey is the corresponding private key.
  • certs is an optional additional set of certificates to include in the CMS structure — like any intermediate CAs in the chain, iykyk 🦋
  • flags is an optional set of flags.

🔥 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
  • CMS_STREAM

why? because they do not make sense in the context of signed receipts, bestie 😭 so don’t come for them, they’re literally not invited 💀

👑 RETURN VALUES 👑

CMS_sign_receipt() returns either a valid CMS_ContentInfo structure or NULL if an error occurred. The error can be obtained from ERR_get_error(3) — that’s your receipts for what went wrong 🧾✨
