SIG(0) uses public/private keys to +authenticate messages. Access control is performed in the same manner as with +TSIG keys; privileges can be granted or denied in ACL directives based +on the key name. + +When a SIG(0) signed message is received, it is only verified if +the key is known and trusted by the server. The server does not attempt +to recursively fetch or validate the key. + +SIG(0) signing of multiple-message TCP streams is not supported. + +The only tool shipped with BIND 9 that generates SIG(0) signed messages +is :iscman:`nsupdate`. |
