How It Works

Flow

  • - Decodes JWT header/payload and verifies HS256 signature against secret.

Accepted Formats

  • - JWT format `header.payload.signature`, Base64URL segments.

Limitations

  • - Verification supports HS256 only.

Notes

  • Use examples to test common scenarios quickly.
  • Review tool outputs before production use.
