💅 verify a CMS signed receipt: CMS_verify_receipt 💅

okay bestie, welcome to CMS_VERIFY_RECEIPT(3ossl) — the OpenSSL page where we verify a CMS signed receipt. It’s giving crypto paperwork, but make it cute. 🎀

🎀 NAME 🎀

CMS_verify_receipt — verify a CMS signed receipt. That’s literally the name, no cap. ✨

✨ SYNOPSIS ✨

#include <openssl/cms.h>

int CMS_verify_receipt(CMS_ContentInfo *rcms, CMS_ContentInfo *ocms,
                       STACK_OF(X509) *certs, X509_STORE *store,
                       unsigned int flags);

🦋 DESCRIPTION 🦋

CMS_verify_receipt() verifies a CMS signed receipt. Here’s the cast, bestie:

  • rcms — the signed receipt to verify. main character energy fr fr.
  • ocms — the original SignedData structure containing the receipt request.
  • certs — a set of certificates in which to search for the signing certificate.
  • store — a trusted certificate store (used for chain verification).
  • flags — an optional set of flags, which can be used to modify the verify operation.

💀 NOTES 💀

This function behaves in a similar way to CMS_verify() except the flag values CMS_DETACHED, CMS_BINARY, CMS_TEXT and CMS_STREAM are not supported since they do not make sense in the context of signed receipts.

so yeah, those four flags are not invited to the receipt party. don’t force it. 🙈

🌸 RETURN VALUES 🌸

CMS_verify_receipt() returns 1 for a successful verification and zero if an error occurred.

The error can be obtained from ERR_get_error(3). if it flops, that’s where the tea is. 😭
