Anleitung: JWT-Generator
JWT-Generator ist ein kostenloses Online-Sicherheits-Tools-Tool, das sign and verify JSON Web Tokens entirely in your browser — HS256, HS384, HS512, RS256 and ES256 run on your own WebCrypto, fresh RSA-2048/EC P-256 pairs export as PKCS#8 and SPKI PEM, exp/iat come back as human dates, and the unsigned "none" algorithm is refused by design. Nothing is uploaded sofort im Browser ausführt. Daten einfügen, Optionen anpassen, Ergebnis in Echtzeit — ohne Installation, ohne Konto, ohne Uploads.

Sign and verify JSON Web Tokens entirely in your browser — HS256, HS384, HS512, RS256 and ES256 run on your own WebCrypto, fresh RSA-2048/EC P-256 pairs export as PKCS#8 and SPKI PEM, exp/iat come back as human dates, and the unsigned "none" algorithm is refused by design. Nothing is uploaded.
- Sicherheits-Tools
- Da alles clientseitig berechnet wird, ist JWT-Generator auch für sensible Daten wie API-Keys sicher.
Anleitung
JWT-Generator in drei Schritten:
- Daten ins Eingabefeld einfügen (oder Beispiel laden).
- Optionen für das Ziel format anpassen.
- Ausgabe kopieren, herunterladen oder prüfen — Live-Aktualisierung.
Ausführen
Beispiele
Builds a signed HS256 token whose exp (2030-01-01 UTC) is shown with its human UTC/local time. Secrets never leave the browser and the unsigned "none" algorithm is refused by design — for inspecting foreign tokens use the Decoder / Verifier pages (the loopback pair of this generator).
Ausgabe（由工具此刻实时生成）
Signed with HS256 — the token below is the compact serialization:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiIyNjE3MyIsInN1YiI6ImRlbW8iLCJleHAiOjE4OTM0NTYwMDB9.-ZCXzFd37b5ZNaDyjyUHfPXEyKzs9ta4TTj5AyO5xpE
Header: {"alg":"HS256","typ":"JWT"}
Payload: {"iss":"26173","sub":"demo","exp":1893456000}
Claim times (your browser clock):
Expires at: 1893456000 = 2030-01-01T00:00:00.000Z UTC | local: Tue Jan 01 2030 00:00:00 GMT+0000 (Coordinated Universal Time) -> still valid
Paste the token into the Verify mode on this same page (or the JWT Verifier page) to check it; to inspect claims without verifying use the JWT Decoder page. Everything ran in your browser — the secret and key never left this machine.
此输出由工具真实运行产生，并非人工编写。
