Sıkça Sorulan Sorular
Is JWT secure?
JWT is secure when used correctly. The token content is only base64url-encoded, not encrypted — the signature ensures integrity. Sensitive data should not be placed in the payload. It should be transmitted over HTTPS and the secret key must be kept private.
How should the secret key be stored?
You should never store the secret key on the client side or in source code. Use environment variables (.env), secret manager services (AWS Secrets Manager, HashiCorp Vault, etc.). This tool is for development and testing purposes only.
