CMS_SIGN_RECEIPT(3)        Library Functions Manual        CMS_SIGN_RECEIPT(3)

NAME
     CMS_sign_receipt - create a CMS signed receipt

SYNOPSIS
     #include <openssl/cms.h>

     CMS_ContentInfo *
     CMS_sign_receipt(CMS_SignerInfo *si, X509 *signcert, EVP_PKEY *pkey,
         STACK_OF(X509) *certs, unsigned int flags);

DESCRIPTION
     CMS_sign_receipt() creates a new CMS SignedData structure containing a
     signed Receipt as its embedded content.  si is the SignerInfo structure
     containing the signed receipt request.  signcert is the certificate to
     sign with, pkey is the corresponding private key.  certs is an optional
     additional set of certificates to include in the CMS structure (for
     example any intermediate CAs in the chain).

     This functions behaves in a similar way to CMS_sign(3) except that the
     flags values CMS_DETACHED, CMS_BINARY, CMS_NOATTR, CMS_TEXT, and
     CMS_STREAM are not supported since they do not make sense in the context
     of signed receipts.

RETURN VALUES
     CMS_sign_receipt() returns either a valid CMS_ContentInfo structure or
     NULL if an error occurred.  The error can be obtained from
     ERR_get_error(3).
