=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)>
