=pod =head1 NAME CMS_verify_receipt - verify a CMS signed receipt =head1 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); =head1 DESCRIPTION CMS_verify_receipt() verifies a CMS signed receipt. B<rcms> is the signed receipt to verify. B<ocms> is the original SignedData structure containing the receipt request. B<certs> is a set of certificates in which to search for the signing certificate. B<store> is a trusted certificate store (used for chain verification). B<flags> is an optional set of flags, which can be used to modify the verify operation. =head1 NOTES This functions behaves in a similar way to CMS_verify() except the flag values B<CMS_DETACHED>, B<CMS_BINARY>, B<CMS_TEXT> and B<CMS_STREAM> are not supported since they do not make sense in the context of signed receipts. =head1 RETURN VALUES CMS_verify_receipt() returns 1 for a successful verification and zero if an error occurred. The error can be obtained from L<ERR_get_error(3)|ERR_get_error(3)> =head1 SEE ALSO L<ERR_get_error(3)|ERR_get_error(3)>, L<CMS_sign_receipt(3)|CMS_sign_receipt(3)>, L<CMS_verify(3)|CMS_verify(3)>, =head1 HISTORY CMS_verify_receipt() was added to OpenSSL 0.9.8 =cut
