Cara pakai: JWT Signer
JWT Signer adalah alat Alat keamanan online gratis yang seal a payload with RS256 (or HS256/HS384/HS512 and ES256) right in the browser: paste claims and a PKCS#8 private key — or generate an RSA/EC pair on the spot — then verify the result on the same page. "none" is never accepted, and your keys never leave this machine seketika di peramban Anda. Tempel data, atur opsi, dan dapatkan hasil secara langsung — tanpa instalasi, tanpa daftar, tanpa unggah.

Contoh
Same builder, seeded for signing flows; the live page pre-selects RS256 and activates as soon as you paste a PKCS#8 private key — or generate an RSA/EC pair right on the page (SPKI public export included). Tokens made here verify on this same page.
Keluaran（由工具此刻实时生成）
Signed with HS256 — the token below is the compact serialization:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1aWQiOjQyLCJyb2xlIjoiZGVtbyJ9.j3xOY9SeZp9EnaVLrgVmaRQxSi5ppfol0ImzkJUsr4g
Header: {"alg":"HS256","typ":"JWT"}
Payload: {"uid":42,"role":"demo"}
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.
