.SH NAME
CMS_sign_receipt \- create a CMS signed receipt
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/cms.h>
\&
\& CMS_ContentInfo *CMS_sign_receipt(CMS_SignerInfo *si, X509 *signcert,
\&                                   EVP_PKEY *pkey, STACK_OF(X509) *certs,

.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBCMS_sign_receipt()\fR creates and returns a CMS signed receipt structure. \fBsi\fR is
the \fBCMS_SignerInfo\fR structure containing the signed receipt request.
\&\fBsigncert\fR is the certificate to sign with, \fBpkey\fR is the corresponding
private key.  \fBcerts\fR is an optional additional set of certificates to include
in the CMS structure (for example any intermediate CAs in the chain).
.PP
\&\fBflags\fR is an optional set of flags.
.SH NOTES
.IX Header "NOTES"
This functions behaves in a similar way to \fBCMS_sign()\fR except the flag values
\&\fBCMS_DETACHED\fR, \fBCMS_BINARY\fR, \fBCMS_NOATTR\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_sign_receipt()\fR returns either a valid CMS_ContentInfo structure or NULL if
an error occurred.  The error can be obtained from \fBERR_get_error\fR\|(3).
