Outcome
A separated view of decoded fields, verification status, weak algorithms, expiry timestamps, and supporting certificate material.

Workflow
區分 JWT 解碼與簽章驗證，在本地檢查 token、憑證與 key material。
Use this path before debugging JWT claims, certificates, JWKs, or hash evidence copied from an auth incident or staging integration.
A separated view of decoded fields, verification status, weak algorithms, expiry timestamps, and supporting certificate material.
These workflow pages do not process, collect, or store tool input. Use the linked tools directly and review their trust badges before handling sensitive data.
Start with the local token decoder to inspect header and payload fields while keeping signature verification as a separate step.
JWT 解碼器Review exp, nbf, iat, and alg values, especially none, MD5-era hashes, and tokens copied from untrusted channels.
JWT 工作台Use the verifier with the expected secret or public key before treating decoded claims as trustworthy.
JWT 簽章驗證器Normalize JWKs, public keys, and certificate data when the verification key is unclear.
公鑰 JWK 助手Avoid common JWT handling mistakes when reviewing decoded or verified tokens.
Understand certificate chain fields before debugging key and token verification.
Choose hash algorithms deliberately when reviewing evidence or compatibility.
No. Decoding only makes the header and payload readable. Verification requires the expected algorithm and key material.
Inspect certificates when the signing key chain, public key format, or issuer data is part of the verification question.
Share only redacted claims that are necessary for the review. Remove tokens, subject identifiers, emails, and organization-specific secrets.
