mod_http_oauth2: Record hash of client_id to allow future verification RFC 6819 section 5.2.2.2 states that refresh tokens MUST be bound to the client. In order to do that, we must record something that can definitely tie the client to the grant. Since the full client_id is so large (why we have this client_subset function), a hash is stored instead.

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

This module allows you to manually pin certificate fingerprints of
remote servers.

Details
=======

Servers not listed in the configuration are not affected.

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

After installing and enabling this module, you can put fingerprints of
remote servers in your config like this:

``` {.lua}
s2s_auth_fingerprint_digest = "sha1" -- This is the default. Other options are "sha256" and "sha512"
s2s_trusted_fingerprints = {
    ["jabber.org"] = "11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED";
    ["matthewwild.co.uk"] = {
        "FD:7F:B2:B9:4C:C4:CB:E2:E7:48:FB:0D:98:11:C7:D8:4D:2A:62:AA";
        "CF:F3:EC:43:A9:D5:D1:4D:D4:57:09:55:52:BC:5D:73:06:1A:A1:A0";
    };
}

-- If you don't want to fall back to dialback, you can list the domains s2s_secure_domains too
s2s_secure_domains = {
    "jabber.org";
}
```
