#summary S2S authentication using DANE #labels Stage-Alpha,Type-S2SAuth = Introduction = This module implements DANE as described in [http://tools.ietf.org/html/draft-miller-xmpp-dnssec-prooftype Using DNS Security Extensions (DNSSEC) and DNS-based Authentication of Named Entities (DANE) as a Prooftype for XMPP Domain Name Associations]. = Dependencies = This module requires a DNSSEC aware DNS resolver. Prosodys internal DNS module does not support DNSSEC. Therefore, to use this module, a replacement is needed, such as [https://www.zash.se/luaunbound.html this one]. More installation instructions can be found at [https://www.zash.se/prosody-dane.html Prosody with DANE]. = Configuration = After [https://prosody.im/doc/installing_modules installing the module], just add it to `modules_enabled`; {{{ modules_enabled = { ... "s2s_auth_dane"; } }}} = DNS Setup = In order for other services to verify your site using using this plugin, you need to publish TLSA records (and they need to have this plugin). Here's an example using "DANE-EE Cert SHA2-256" for a host named xmpp.example.com serving the domain example.com. {{{ $ORIGIN example.com. ; Your standard SRV record _xmpp-server._tcp.example.com IN SRV 0 0 5269 xmpp.example.com. ; IPv4 and IPv6 addresses xmpp.example.com. IN A 192.0.2.68 xmpp.example.com. IN AAAA 2001:0db8:0000:0000:4441:4e45:544c:5341 ; The DANE TLSA records. These three are equivalent, you would use only one of them. ; First, using symbolic names: _5269._tcp.xmpp.example.com. 300 IN TLSA DANE-EE Cert SHA2-256 E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 ; Using numbers: _5269._tcp.xmpp.example.com. 300 IN TLSA 3 0 1 E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 ; Raw binary format, should work even with very old DNS tools: _5269._tcp.xmpp.example.com. 300 IN TYPE52 \# 35 030001E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 }}} [http://www.internetsociety.org/deploy360/dnssec/tools/ List of DNSSEC and DANE tools] = Further reading = * [http://tools.ietf.org/html/draft-ietf-dane-ops DANE TLSA implementation and operational guidance] = Compatibility = Requires 0.9 or above.
