mod_http_oauth2: Always show early errors to user Before having validated the client_id, communicating an error back to the client via redirect would make this an open redirect, so we may just as well skip past that logic, and especially the warning log message.

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."
