자주 묻는 질문
Quick answers.
›Which signing algorithms are supported?
The tool supports symmetric signing (HS256, HS384, HS512) and asymmetric signing including RSA (RS/PS), Elliptic Curve (ES), and Edwards-curve (EdDSA/Ed25519).
›Are my private keys secure?
Yes. All signing happens locally on your device using the browser's native Web Crypto API. Your private keys and secrets never leave your browser.
›What happens if I use an invalid key format?
The tool validates your key against the selected algorithm. For asymmetric algorithms, ensure your key is in a supported format like PEM or JWK.
›Can I add custom headers or claims?
Yes. You can edit the Header and Payload JSON objects directly before signing to include standard claims like `exp` or custom application data.
