6 This module implements DANE as described in |
|
7 [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]. |

|
11 This module requires a DNSSEC aware DNS resolver. Prosodys internal DNS |
|
12 module does not support DNSSEC. Therefore, to use this module, a |
|
13 replacement is needed, such as [https://www.zash.se/luaunbound.html this one]. |
|
14 |
|
15 More installation instructions can be found at [https://www.zash.se/prosody-dane.html Prosody with DANE]. |

19 After [https://prosody.im/doc/installing_modules installing the module], just add it to `modules_enabled`; |

|
30 In order for other services to verify your site using using this plugin, |
|
31 you need to publish TLSA records (and they need to have this plugin). |
|
32 Here's an example using "DANE-EE Cert SHA2-256" for a host named |
|
33 xmpp.example.com serving the domain example.com. |
|
34 |
|
35 {{{ |
|
36 $ORIGIN example.com. |
|
37 ; Your standard SRV record |
|
38 _xmpp-server._tcp.example.com IN SRV 0 0 5269 xmpp.example.com. |
|
39 ; IPv4 and IPv6 addresses |
|
40 xmpp.example.com. IN A 192.0.2.68 |
|
41 xmpp.example.com. IN AAAA 2001:0db8:0000:0000:4441:4e45:544c:5341 |
|
42 |
|
43 ; The DANE TLSA records. These three are equivalent, you would use only one of them. |
|
44 ; First, using symbolic names: |
|
45 _5269._tcp.xmpp.example.com. 300 IN TLSA DANE-EE Cert SHA2-256 E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 |
|
46 ; Using numbers: |
|
47 _5269._tcp.xmpp.example.com. 300 IN TLSA 3 0 1 E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 |
|
48 ; Raw binary format, should work even with very old DNS tools: |
|
49 _5269._tcp.xmpp.example.com. 300 IN TYPE52 \# 35 030001E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 |
