+Compare the list of enabled modules with
+[XEP-0479: XMPP Compliance Suites 2023] and produce basic report to the
+Prosody log file.
+
+If installed with the Prosody plugin installer then all modules needed for a green checkmark should be included. (With prosody 0.12 only [mod_cloud_notify] is not included with prosody and we need the community module)

16 First, download and add the module to `module_enabled`. Then you can |
1842 | 17 decide on what policy you want to have. |
18 | |
19 Requiring ciphers with forward secrecy is the most simple to set up. | |
20 | |
21 ``` lua | |
22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
23 ``` | |
24 | |
25 A more complicated example: | |
26 | |
27 ``` lua | |
28 tls_policy = { | |
29 c2s = { | |
30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
33 } | |
34 s2s = { | |
35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
37 authentication = "RSA"; -- with RSA authentication | |
38 }; | |
39 } | |
40 ``` | |
41 | |
42 # Compatibility | |

44 Requires LuaSec 0.5 | |
