Implements OpenID Connect Core 1.0 and OpenID Connect Discovery 1.0.
Implements UMA2 - User Managed Access, an extension to OIDC/OAuth2. Use feature flag uma2
to enable this feature.
It supports Microsoft OIDC with feature microsoft
. This adds methods for authentication and token validation, those skip issuer check.
This library is a quick and dirty rewrite of inth-oauth2 and oidc to use async / await. Basic idea was to solve particular task, as result most of good ideas from original crates were perverted and over-simplified.
Using reqwest for the HTTP client and biscuit for Javascript Object Signing and Encryption (JOSE).
Add dependency to Cargo.toml:
[dependencies]
openid = "0.9"
By default it uses native tls, if you want to use rustls
:
[dependencies]
openid = { version = "0.9", default-features = false, features = ["rustls"] }
Use case: Warp web server with JHipster generated frontend and Google OpenID Connect
This example provides only Rust part, assuming just default JHipster frontend settings.
