mod_conversejs: Serve base app at / This makes things slightly less awkward for the browser to figure out which URLs belong to a PWA. The app's "start URL" was previously without the '/' and therefore was not considered within the scope of the PWA. Now the canonical app URL will always have a '/'. Prosody/mod_http should take care of redirecting existing links without the trailing / to the new URL. If you have an installation at https://prosody/conversejs then it is now at https://prosody/conversejs/ (the first URL will now redirect to the second URL if you use it). The alternative would be to make the PWA scope include the parent, i.e. the whole of https://prosody/ in this case. This might get messy if other PWAs are provided by the same site or Prosody installation, however.

summary: Warn users of obsolete TLS Versions in clients
---


TLS 1.0 and TLS 1.1 are obsolete. This module warns clients if they are using those versions, to prepare for disabling them. (If you use the default prosody config, this module will be unnessesary in its default setting, since these protocols are not allowed anymore by any supported prosody version.)

This module can be used to warn from TLS1.2 if you want to switch to modern security in the near future.

# Configuration

``` {.lua}
modules_enabled = {
    -- other modules etc
    "warn_legacy_tls";
}

-- This is the default, you can leave it out if you don't wish to
-- customise or translate the message sent.
-- '%s' will be replaced with the TLS version in use.
legacy_tls_warning = [[
Your connection is encrypted using the %s protocol, which has been demonstrated to be insecure and will be disabled soon.  Please upgrade your client.
]]

--You may want to warn about TLS1.2 these days too (This note added 2024), by default prosody will not even allow connections from TLS <1.2
--Example:
legacy_tls_versions = { "TLSv1", "TLSv1.1", "TLSv1.2" }
```

## Options

`legacy_tls_warning`
:   A string. The text of the message sent to clients that use outdated
    TLS versions. Default as in the above example.

`legacy_tls_versions`
:   Set of TLS versions, defaults to
    `{ "SSLv3", "TLSv1", "TLSv1.1" }`{.lua}, i.e. TLS \< 1.2.
