mod_http_oauth2: Reject loopback URIs as client_uri This really should be a proper website with info, https://localhost is not good enough. Ideally we'd validate that it's got proper DNS and is actually reachable, but triggering HTTP or even DNS lookups seems like it would carry abuse potential that would best to avoid.

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."
