mod_http_oauth2: Fix use of arbitrary ports in loopback redirect URIs Per draft-ietf-oauth-v2-1-08#section-8.4.2 > The authorization server MUST allow any port to be specified at the > time of the request for loopback IP redirect URIs, to accommodate > clients that obtain an available ephemeral port from the operating > system at the time of the request. Uncertain if it should normalize the host part, but it also seems harmless to treat IPv6 and IPv4 the same here. One thing is that "localhost" is NOT RECOMMENDED because it can sometimes be pointed to non-loopback interfaces via DNS or hosts file.

Introduction
============

This module was written to encourage usage of End-to-end encryption for chat and MUC messages. It can be configured to warn the sender after every plaintext/unencrypted message or to block all plaintext/unencrypted messages. It also supports MUC and JID whitelisting, so administrators can for example whitelist public support MUCs ;-)

Configuration
=============

Enable the module as any other:

    modules_enabled = {
      "e2e_policy";
    }

You can then set some options to configure your desired policy:

  Option                                 Default        Description
  ------------------------------------   ------------   -------------------------------------------------------------------------------------------------------------------------------------------------
  e2e\_policy\_chat                      `"optional"`   Policy for chat messages. Possible values: `"none"`, `"optional"` and `"required"`.
  e2e\_policy\_muc                       `"optional"`   Policy for MUC messages. Possible values: `"none"`, `"optional"` and `"required"`.
  e2e\_policy\_whitelist                 `{ }`          Make this module ignore messages sent to and from this JIDs or MUCs.
  e2e\_policy\_message\_optional\_chat   `""`           Set a custom warning message for chat messages.
  e2e\_policy\_message\_required\_chat   `""`           Set a custom error message for chat messages.
  e2e\_policy\_message\_optional\_muc    `""`           Set a custom warning message for MUC messages.
  e2e\_policy\_message\_required\_muc    `""`           Set a custom error message for MUC messages.

Some examples:

    e2e_policy_chat = "optional"
    e2e_policy_muc = "optional"
    e2e_policy_whitelist = { "admin@example.com", "prosody@conference.prosody.im" }
    e2e_policy_message_optional_chat = "For security reasons, OMEMO, OTR or PGP encryption is STRONGLY recommended for conversations on this server."
    e2e_policy_message_required_chat = "For security reasons, OMEMO, OTR or PGP encryption is required for conversations on this server."
    e2e_policy_message_optional_muc = "For security reasons, OMEMO, OTR or PGP encryption is STRONGLY recommended for MUC on this server."
    e2e_policy_message_required_muc = "For security reasons, OMEMO, OTR or PGP encryption is required for MUC on this server."
