CMS_verify_receipt.3ssl - Man Page

verify a CMS signed receipt


 #include <openssl/cms.h>

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


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).

flags is an optional set of flags, which can be used to modify the verify operation.


This functions 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.

Return Values
