|
|
=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)>
