=pod =head1 NAME CMS_sign_receipt - create a CMS signed receipt =head1 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); =head1 DESCRIPTION CMS_sign_receipt() creates and returns a CMS signed receipt structure. B<si> is the B<CMS_SignerInfo> structure containing the signed receipt request. B<signcert> is the certificate to sign with, B<pkey> is the corresponding private key. B<certs> is an optional additional set of certificates to include in the CMS structure (for example any intermediate CAs in the chain). B<flags> is an optional set of flags. =head1 NOTES This functions behaves in a similar way to CMS_sign() except the flag values B<CMS_DETACHED>, B<CMS_BINARY>, B<CMS_NOATTR>, 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_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). =head1 SEE ALSO L<ERR_get_error(3)|ERR_get_error(3)>, L<CMS_verify_receipt(3)|CMS_verify_receipt(3)>, L<CMS_sign(3)|CMS_sign(3)> =head1 HISTORY CMS_sign_receipt() was added to OpenSSL 0.9.8 =cut
