SET inspector
Paste a Security Event Token to decode it, verify its signature and check it against SSF 1.0, CAEP, RISC and the CAEP Interoperability Profile — the same checks the sample Receiver runs.
Keys and expectations (optional)
By default the signing key is found by SSF discovery from the SET’s iss. Override that with a JWKS URL or a pasted JWKS.
The SET is sent to this site’s Worker so it can fetch keys without CORS problems; it is not stored. Don’t paste SETs carrying real personal data into any public tool, this one included.
