For example if one or more KEKRecipientInfo structures -need to be added. New attributes can also be added using the returned -CMS_RecipientInfo structure and the CMS attribute utility functions. - -OpenSSL will by default identify recipient certificates using issuer name -and serial number. If B<CMS_USE_KEYID> is set it will use the subject key -identifier value instead. An error occurs if all recipient certificates do not -have a subject key identifier extension. - -Currently only AES based key wrapping algorithms are supported for B<nid>, -specifically: NID_id_aes128_wrap, NID_id_aes192_wrap and NID_id_aes256_wrap. -If B<nid> is set to B<NID_undef> then an AES wrap algorithm will be used -consistent with B<keylen>. - -=head1 RETURN VALUES - -CMS_add1_recipient_cert() and CMS_add0_recipient_key() return an internal -pointer to the CMS_RecipientInfo structure just added or NULL if an error -occurs. - -=head1 SEE ALSO - -L<ERR_get_error(3)|ERR_get_error(3)>, L<CMS_decrypt(3)|CMS_decrypt(3)>, -L<CMS_final(3)|CMS_final(3)>, - -=head1 HISTORY - -CMS_add1_recipient_cert() and CMS_add0_recipient_key() were added to OpenSSL -0.9.8 - -=cut |
