Finally the RFC Best Current Practice for OAuth 2.0 Security has been approved.
According to the RFC:
> Authorization servers MUST support PKCE [RFC7636].
>
> If a client sends a valid PKCE code_challenge parameter in the authorization request, the authorization server MUST enforce the correct usage of code_verifier at the token endpoint.
Isn’t it time we strengthen PKCE support a bit more?
This PR updates the logic so that PKCE is always verified, even when the Auth Method is not "none".
This change sets the `content-type` header to `application/json` for the response sent to the browser in the app example.
This enables pretty-printing of the userinfo json document in at least Chromium.
With impersonation we assign an actor claim to our JWT/ID Tokens. This change adds the actor claim to the introspection response to follow suit.
This PR also adds the `auth_time` and `amr` claims for consistency.
* feat(op): Add response_mode: form_post
* Fix to parse the template ahead of time
* Fix to render the template in a buffer
* Remove unnecessary import
* Fix test
* Fix example client setting
* Make sure the client not to reuse the content of the response
* Fix error handling
* Add the response_mode param
* Allow implicit flow in the example app
* feat(rp): allow form_post in code exchange callback handler

This change adds Go 1.22 as a build target and drops support for Go 1.20 and older. The golang.org/x/exp/slog import is migrated to log/slog.
Slog has been part of the Go standard library since Go 1.21. Therefore we are dropping support for older Go versions. This is in line of our support policy of "the latest two Go versions".
* feat(op): user slog for logging
integrate with golang.org/x/exp/slog for logging.
provide a middleware for request scoped logging.
BREAKING CHANGES:
1. OpenIDProvider and sub-interfaces get a Logger()
method to return the configured logger;
2. AuthRequestError now takes the complete Authorizer,
instead of only the encoder. So that it may use its Logger() method.
3. RequestError now takes a Logger as argument.
* use zitadel/logging
* finish op and testing
without middleware for now
* minimum go version 1.19
* update go mod
* log value testing only on go 1.20 or later
* finish the RP and example
* ping logging release
* oidc: add regression tests for token claim json
this helps to verify that the same JSON is produced,
after these types are refactored.
* refactor: use struct types for claim related types
BREAKING CHANGE:
The following types are changed from interface to struct type:
- AccessTokenClaims
- IDTokenClaims
- IntrospectionResponse
- UserInfo and related types.
The following methods of OPStorage now take a pointer to a struct type,
instead of an interface:
- SetUserinfoFromScopes
- SetUserinfoFromToken
- SetIntrospectionFromToken
The following functions are now generic, so that type-safe extension
of Claims is now possible:
- op.VerifyIDTokenHint
- op.VerifyAccessToken
- rp.VerifyTokens
- rp.VerifyIDToken
- Changed UserInfoAddress to pointer in UserInfo and
IntrospectionResponse.
This was needed to make omitempty work correctly.
- Copy or merge maps in IntrospectionResponse and SetUserInfo
* op: add example for VerifyAccessToken
* fix: rp: wrong assignment in WithIssuedAtMaxAge
WithIssuedAtMaxAge assigned its value to v.maxAge, which was wrong.
This change fixes that by assiging the duration to v.maxAgeIAT.
* rp: add VerifyTokens example
* oidc: add standard references to:
- IDTokenClaims
- IntrospectionResponse
- UserInfo
* only count coverage for `./pkg/...`
This change implements OAuth2 Token Exchange in OP according to RFC 8693 (and client code)
Some implementation details:
- OP parses and verifies subject/actor tokens natively if they were issued by OP
- Third-party tokens verification is also possible by implementing additional storage interface
- Token exchange can issue only OP's native tokens (id_token, access_token and refresh_token) with static issuer
* feat(op): dynamic issuer depending on request / host
BREAKING CHANGE: The OpenID Provider package is now able to handle multiple issuers with a single storage implementation. The issuer will be selected from the host of the request and passed into the context, where every function can read it from if necessary. This results in some fundamental changes:
- `Configuration` interface:
- `Issuer() string` has been changed to `IssuerFromRequest(r *http.Request) string`
- `Insecure() bool` has been added
- OpenIDProvider interface and dependants:
- `Issuer` has been removed from Config struct
- `NewOpenIDProvider` now takes an additional parameter `issuer` and returns a pointer to the public/default implementation and not an OpenIDProvider interface:
`NewOpenIDProvider(ctx context.Context, config *Config, storage Storage, opOpts ...Option) (OpenIDProvider, error)` changed to `NewOpenIDProvider(ctx context.Context, issuer string, config *Config, storage Storage, opOpts ...Option) (*Provider, error)`
- therefore the parameter type Option changed to the public type as well: `Option func(o *Provider) error`
- `AuthCallbackURL(o OpenIDProvider) func(string) string` has been changed to `AuthCallbackURL(o OpenIDProvider) func(context.Context, string) string`
- `IDTokenHintVerifier() IDTokenHintVerifier` (Authorizer, OpenIDProvider, SessionEnder interfaces), `AccessTokenVerifier() AccessTokenVerifier` (Introspector, OpenIDProvider, Revoker, UserinfoProvider interfaces) and `JWTProfileVerifier() JWTProfileVerifier` (IntrospectorJWTProfile, JWTAuthorizationGrantExchanger, OpenIDProvider, RevokerJWTProfile interfaces) now take a context.Context parameter `IDTokenHintVerifier(context.Context) IDTokenHintVerifier`, `AccessTokenVerifier(context.Context) AccessTokenVerifier` and `JWTProfileVerifier(context.Context) JWTProfileVerifier`
- `OidcDevMode` (CAOS_OIDC_DEV) environment variable check has been removed, use `WithAllowInsecure()` Option
- Signing: the signer is not kept in memory anymore, but created on request from the loaded key:
- `Signer` interface and func `NewSigner` have been removed
- `ReadySigner(s Signer) ProbesFn` has been removed
- `CreateDiscoveryConfig(c Configuration, s Signer) *oidc.DiscoveryConfiguration` has been changed to `CreateDiscoveryConfig(r *http.Request, config Configuration, storage DiscoverStorage) *oidc.DiscoveryConfiguration`
- `Storage` interface:
- `GetSigningKey(context.Context, chan<- jose.SigningKey)` has been changed to `SigningKey(context.Context) (SigningKey, error)`
- `KeySet(context.Context) ([]Key, error)` has been added
- `GetKeySet(context.Context) (*jose.JSONWebKeySet, error)` has been changed to `KeySet(context.Context) ([]Key, error)`
- `SigAlgorithms(s Signer) []string` has been changed to `SigAlgorithms(ctx context.Context, storage DiscoverStorage) []string`
- KeyProvider interface: `GetKeySet(context.Context) (*jose.JSONWebKeySet, error)` has been changed to `KeySet(context.Context) ([]Key, error)`
- `CreateIDToken`: the Signer parameter has been removed
