CMS_VERIFY_RECEIPT(3)      Library Functions Manual      CMS_VERIFY_RECEIPT(3)

NAME
     CMS_verify_receipt - verify a CMS signed receipt

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.  rcms is the signed
     receipt to verify.  ocms is the original SignedData structure containing
     the receipt request.  certs is a set of certificates in which to search
     for the signing certificate.  store is a trusted certificate store (used
     for chain verification).

     This functions behaves in a similar way to CMS_verify(3) except that the
     flags 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.

RETURN VALUES
     CMS_verify_receipt() returns 1 for a successful verification or 0 if an
     error occurred.

     The error can be obtained from ERR_get_error(3).
