mod_http_oauth2: Advertise the currently supported id_token signing algorithm
This field is REQUIRED. The algorithm RS256 MUST be included, but isn't
because we don't implement it, as that would require implementing a pile
of additional cryptography and JWT stuff. Instead the id_token is
signed using the client secret, which allows verification by the client,
since it's a shared secret per OpenID Connect Core 1.0 § 10.1 under
Symmetric Signatures.
OpenID Connect Discovery 1.0 has a lot of REQUIRED and MUST clauses that
are not supported here, but that's okay because this is served from the
RFC 8414 OAuth 2.0 Authorization Server Metadata .well-known endpoint!

--- labels: - Stage-Beta summary: "Fast Authentication Streamlining Tokens" rockspec: dependencies: - mod_sasl2 --- This module implements a mechanism via which clients can exchange a password for a secure token, improving security and streamlining future reconnections. At the time of writing, the XEP that describes the FAST protocol is still working its way through the XSF standards process. You can [view the FAST XEP proposal here](https://xmpp.org/extensions/inbox/xep-fast.html). This module depends on [mod_sasl2]. ## Configuration | Name | Description | Default | |---------------------------|--------------------------------------------------------|-----------------------| | sasl2_fast_token_ttl | Default token expiry (seconds) | `86400*21` (21 days) | | sasl2_fast_token_min_ttl | Time before tokens are eligible for rotation (seconds) | `86400` (1 day) | The `sasl2_fast_token_ttl` option determines the length of time a client can remain disconnected before being "logged out" and needing to authenticate with a password. Clients must perform at least one FAST authentication within this period to remain active. The `sasl2_fast_token_min_ttl` option defines how long before a token will be rotated by the server. By default a token is rotated if it is older than 24 hours. This value should be less than `sasl2_fast_token_ttl` to prevent clients being logged out unexpectedly.
