This moves the OpenID Connect storage from memory into the SQL storage, making it persistent and allowing it to be used with clustered deployments like the rest of Authelia.
This implements Webauthn. Old devices can be used to authenticate via the appid compatibility layer which should be automatic. New devices will be registered via Webauthn, and devices which do not support FIDO2 will no longer be able to be registered. At this time it does not fully support multiple devices (backend does, frontend doesn't allow registration of additional devices). Does not support passwordless.
Adds encryption to the U2F public keys. While the public keys cannot be used to authenticate, only to validate someone is authenticated, if a rogue operator changed these in the database they may be able to bypass 2FA. This prevents that.
This replaces the standard duo_devices upsert with a PostgreSQL specific one and ensures the u2f_devices upsert uses the new unique key for the ON CONFLICT check.
Allow users to configure the TOTP Algorithm and Digits. This should be used with caution as many TOTP applications do not support it. Some will also fail to notify the user that there is an issue. i.e. if the algorithm in the QR code is sha512, they continue to generate one time passwords with sha1. In addition this drastically refactors TOTP in general to be more user friendly by not forcing them to register a new device if the administrator changes the period (or algorithm).
Fixes#1226.
This adds an AES-GCM 256bit encryption layer for storage for sensitive items. This is only TOTP secrets for the time being but this may be expanded later. This will require a configuration change as per https://www.authelia.com/docs/configuration/migration.html#4330.
Closes#682
This is a massive overhaul to the SQL Storage for Authelia. It facilitates a whole heap of utility commands to help manage the database, primary keys, ensures all database requests use a context for cancellations, and paves the way for a few other PR's which improve the database.
Fixes#1337
