よくある質問
Why validate JWTs after generation?
Catches encoding bugs, wrong algorithms, and missing claims before they reach production. A malformed JWT causes silent auth failures that are hard to debug.
What claims should every JWT have?
At minimum: sub (subject), iat (issued at), exp (expiration). Add iss (issuer) and aud (audience) for multi-service architectures.
