* fix: allow expired ID token hint to end sessions
This change adds a specific error for expired ID Token hints, including too old "issued at" and "max auth age".
The error is returned VerifyIDTokenHint so that the end session handler can choose to ignore this error.
This fixes the behavior to be in line with [OpenID Connect RP-Initiated Logout 1.0, section 4](https://openid.net/specs/openid-connect-rpinitiated-1_0.html#ValidationAndErrorHandling).
* Tes IDTokenHintExpiredError
BREAKING CHANGE:
- The various verifier types are merged into a oidc.Verifir.
- oidc.Verfier became a struct with exported fields
* use type aliases for oidc.Verifier
this binds the correct contstructor to each verifier usecase.
* fix: handle the zero cases for oidc.Time
* add unit tests to oidc verifier
* fix: correct returned field for JWTTokenRequest
JWTTokenRequest.GetIssuedAt() was returning the ExpiresAt field.
This change corrects that by returning IssuedAt instead.
* 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/...`
