Gebruiksaanwijzing: JWT-Generator
JWT-Generator is een gratis online Beveiligingstools-tool die 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 direct in je browser doet. Plak je gegevens, stel de opties in en krijg het resultaat realtime — geen installatie, geen account, geen uploads.

Uitvoeren
Voorbeelden
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).
Uitvoer（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。
