CMS_VERIFY_RECEIPT(3) FreeBSD 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).
