PASSporT & Identity Header Decoder

A jwt.io-style decoder for STIR/SHAKEN, Rich Call Data (RCD), and diversion (div) PASSporTs — and the SIP Identity header(s) that carry them.?

Paste one or more Identity headers (one per line) — a diverted call carries several. Everything runs in your browser. ● client-side only   Guide →   Certificate decoder →

Input

A SIP Identity header value (RFC 8224 §4: <JWT>;info=<x5u>;alg=ES256;ppt=…) or a bare PASSporT JWT (header.payload.signature). For a diversion chain, paste each header on its own line.
