Choose a debugger Protocol
Which identity protocol do you want to debug?
OAuth2 / OIDC Protocol Authorization Code, Implicit, Client Credentials, Resource Owner, Device and Token Exchange grants, all three OIDC flows, plus JWT, JWKS, introspection and userinfo tools. SAML Protocol SAML 2.0 SP-initiated SSO: load IdP metadata, build and sign an AuthnRequest, capture the SAMLResponse at the ACS, and inspect the assertion. WS-Trust Protocol WS-Trust 1.0–1.4 against an STS: build a RequestSecurityToken for Issue, Renew, Validate or Cancel, sign or encrypt it, and inspect the issued token. SD-JWT VC Issuance Issue an SD-JWT VC (RFC 9901) over OID4VCI: wallet-initiated or from an issuer’s Credential Offer, prove possession of a holder key, inspect the disclosures, and refresh it. SD-JWT VC Presentation Present an SD-JWT VC over OID4VP: read the verifier’s DCQL query, choose which Disclosures to send, sign the Key Binding JWT over its nonce, and read the verdict. OIDC Dynamic Client Registration Register a Relying Party at the OP’s registration endpoint, then read, update or delete it with the Registration Access Token. OAuth2 Token Exchange Exchange one token for another (RFC 8693): impersonation or delegation with a subject_token, an optional actor_token and an audience — on the results page after a flow. WS-Federation Protocol WS-Federation Passive Requestor Profile: load federation metadata, build a wa=wsignin1.0 sign-in request, and inspect the SAML token in the wresult.
