Cara pakai: Generator JWT

Deskripsi

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.

• Alat keamanan
• Karena semuanya dihitung di sisi klien, Generator JWT aman untuk data sensitif seperti kunci API.

Cara pakai

Menggunakan Generator JWT butuh tiga langkah:

1. Tempel data ke kotak input (atau muat contoh).
2. Sesuaikan opsi dengan format yang diinginkan.
3. Salin, unduh, atau periksa hasil — diperbarui secara langsung.

Contoh

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).

Keluaran（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。

FAQ

Perlu diketahui

• 全部计算在浏览器端完成，因此超大输入受限于标签页内存，而非服务器上传限制。
