CMS_verify_receipt \- verify a CMS signed receipt
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/cms.h>
\&
\& int CMS_verify_receipt(CMS_ContentInfo *rcms, CMS_ContentInfo *ocms,
\&                        STACK_OF(X509) *certs, X509_STORE *store,
\&                        unsigned int flags);

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBCMS_verify_receipt()\fR verifies a CMS signed receipt. \fBrcms\fR is the signed
receipt to verify. \fBocms\fR is the original SignedData structure containing the
receipt request. \fBcerts\fR is a set of certificates in which to search for the
signing certificate. \fBstore\fR is a trusted certificate store (used for chain
verification).
.PP
\&\fBflags\fR is an optional set of flags, which can be used to modify the verify
operation.
.SH NOTES
.IX Header "NOTES"
This functions behaves in a similar way to \fBCMS_verify()\fR except the flag values
\&\fBCMS_DETACHED\fR, \fBCMS_BINARY\fR, \fBCMS_TEXT\fR and \fBCMS_STREAM\fR are not
supported since they do not make sense in the context of signed receipts.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBCMS_verify_receipt()\fR returns 1 for a successful verification and zero if an
error occurred.
.PP
The error can be obtained from \fBERR_get_error\fR\|(3)
