Milestone version 2.0 of Ory Hydra, the OpenID Certified OAuth 2.0 and OpenID Connect Server, is out.
How Apple broke "Sign in with Apple" with an unannounced and silent redirect
This milestone release impacts most of Ory’s installed base. While we are thrilled to unveil Ory Hydra 2.0, we would strongly suggest reading this document carefully and to the end.
Open Source software is not easy. Besides the community version Ory Hydra 2.0, Ory now provides the Ory OAuth2 & OpenID service on the Ory Network making this release a major event for Ory and the entire Ory Community.
Ory Hydra 2.0 is available now. Install the Ory CLI for the best developer experience.
# This example works best in Bash
bash <(curl https://raw.githubusercontent.com/ory/meta/master/install.sh) -b . ory
sudo mv ./ory /usr/local/bin/
# Or with Homebrew installed
brew install ory/tap/cli
create a new project (you may also use Docker)
ory create project --name "Ory Hydra 2.0 Example"
project_id="{set to the id from output}"
and follow the quick & easy steps below.
Create an OAuth 2.0 Client, and run the OAuth 2.0 Client Credentials flow:
ory create oauth2-client --project $project_id \
--name "Client Credentials Demo" \
--grant-type client_credentials
client_id="{set to client id from output}"
client_secret="{set to client secret from output}"
ory perform client-credentials --client-id=$client_id --client-secret=$client_secret --project $project_id
access_token="{set to access token from output}"
ory introspect token $access_token --project $project_id
Try out the OAuth 2.0 Authorize Code grant right away!
By accepting permissions openid and offline_access at the consent screen,
Ory refreshes and OpenID Connect ID token,
ory create oauth2-client --project $project_id \
--name "Authorize Code with OpenID Connect Demo" \
--grant-type authorization_code \
--response-type code \
--redirect-uri ttp://127.0.0.1:4446/callback
code_client_id="{set to client id from output}"
code_client_secret="{set to client secret from output}"
ory perform authorization-code \
--project $project_id \
--client-id $code_client_id \
--client-secret $code_client_secret
code_access_token="{set to access token from output}"
ory introspect token $code_access_token --project $project_id
What's changed in Ory Hydra 2.0?
JSON Web Token profile is now fully supported, read more here!
Ory Identities is now compatible with the Ory OAuth2 Login and Consent Flow. This means, for example, that Ory Kratos can be the login provider for Ory Hydra with a bit of configuration.
The Ory Network enables has this integration as a default.
Ory Hydra 2.0 now natively supports key types such as ES256 for signing ID Tokens and OAuth 2.0 Access Tokens in JWT format.
Additionally, the key naming mechanism was updated to conform with industry best practices.
Ory Hydra 2.0 ships a complete refactoring of the internal database structure, reducing database storage at scale and optimizing query performance.
All primary keys are now UUIDs to avoid hotspots in distributed systems. Please note that as part of this change it is no longer possible to choose the OAuth 2.0 Client ID. Instead, Ory chooses the best-performing ID format for the petabyte scale.
Ory chose to denormalize tables that had a negative performance impact due to excessive JOIN statements.
Using BCrypt as the primary hashing algorithm for OAuth 2.0 Client Secrets creates excessive CPU consumption at scale. OAuth 2.0 Client Secrets are auto-generated in Ory Hydra 2.x, removing the need for excessive hashing costs.
The new PKBDF2 hasher can be fine-tuned to support hashing at scale without a significant threat model impact.
This section only applies in scenarios where Ory Hydra is working in a do-it-yourself fashion e.g. on Docker. An Ory Hydra 2.0 compatible service is already available on the Ory Network.
The database schema changed significantly from the previous structure. Please be aware that there might be a period where the database tables will be locked for writes while the upgrade runs.
A full backup of the database before upgrading is essential! We recommend trying out the upgrade on a copy of a production database first.
To run the SQL migrations using:
hydra migrate sql $DSN
Ory Hydra 1.x is a crucial service at Ory. Version 2.0 streamlines the APIs and SDKs to follow Ory API’s semantics and specification.
To better support TB-scale environments, the OAuth2 Client HTTP API's query
parameters for pagination have changed from limit and offset to page_token
and page_size. The page_token is an opaque string contained in the HTTP
Link Header, which expresses the next, previous, first, and last page.
Administrative endpoints now have an /admin prefix (e.g. POST /admin/keys
instead of POST /keys). Existing administrative endpoints will redirect to
this new prefixed path for backward compatibility.
HTTP endpoint /oauth2/flush, used to flush inactive access tokens was
deprecated and has been removed. Please use hydra janitor instead.
To conform with the Ory V1 SDK, several SDK methods and payloads were renamed. Please check the CHANGELOG for a complete list of changes.
The iss (issuer) value no longer appends a trailing slash but instead uses the
raw value set in the config.
Setting
urls:
self:
issuer: https://auth.example.com
has changed
- "iss": "https://auth.example.com/"
+ "iss": "https://auth.example.com"
To set a trailing slash make sure to set it in the config value:
urls:
self:
issuer: https://auth.example.com/
Flags --dangerous-allow-insecure-redirect-url and --dangerous-force-http
have been removed. Use the --dev flag instead to denote a development
environment with reduced security restrictions.
We now recommend using the Ory CLI to manage OAuth2 resources. As part of this restructuring, some of the commands were renamed. Here are some examples:
- hydra client create
+ ory create oauth2-client
- hydra clients list
+ ory list oauth2-clients
Additionally, array arguments now use the singular form:
hydra create client \
- --redirect-uris foo --redirect-uris bar \
+ --redirect-uri foo --redirect-uri bar \
- --grant-types foo --grant-types bar \
+ --grant-type foo --grant-type bar \
- --response-types foo --response-types bar \
+ --response-type foo --response-type bar \
- --allowed-cors-origins foo --allowed-cors-origins bar \
+ --allowed-cors-origin foo --allowed-cors-origin bar \
- --post-logout-callbacks foo --post-logout-callbacks bar \
+ --post-logout-callback foo --post-logout-callback bar
To manage resources in a do-it-yourself installation, continue using the hydra
CLI.
Please check the CHANGELOG for a complete list of changes.
Ory Hydra 2.0 ships with support for OpenTelemetry. The previous telemetry solution using OpenTracing format is deprecated with this release.
