See the COPYRIGHT file distributed with this work for additional +.. information regarding copyright ownership. + +TKEY +---- + +TKEY (Transaction KEY) is a mechanism for automatically negotiating a +shared secret between two hosts, originally specified in :rfc:`2930`. + +There are several TKEY "modes" that specify how a key is to be generated +or assigned. BIND 9 implements only one of these modes: Diffie-Hellman +key exchange. Both hosts are required to have a KEY record with +algorithm DH (though this record is not required to be present in a +zone). + +The TKEY process is initiated by a client or server by sending a query +of type TKEY to a TKEY-aware server. The query must include an +appropriate KEY record in the additional section, and must be signed +using either TSIG or SIG(0) with a previously established key. The +server's response, if successful, contains a TKEY record in its +answer section. After this transaction, both participants have +enough information to calculate a shared secret using Diffie-Hellman key +exchange. The shared secret can then be used to sign subsequent +transactions between the two servers. + +TSIG keys known by the server, including TKEY-negotiated keys, can be +listed using :option:`rndc tsig-list`. + +TKEY-negotiated keys can be deleted from a server using +:option:`rndc tsig-delete`. This can also be done via the TKEY protocol +itself, by sending an authenticated TKEY query specifying the "key +deletion" mode. |
