How secure is Kalp Studio?

Answer  

As far as platform security is concerned JSON Web Tokens (JWT) tokens are being used.
JWT is a compact, URL-safe means of representing claims to be transferred between two parties. JWTs can be used for authentication and authorization in web applications. The typical flow involves a user logging in, the server generating a JWT, and the client (usually a web browser) storing the token and sending it with subsequent requests.

Here's a basic overview of how JWT-based authentication works:

User Authentication:

• When a user logs in, the server verifies the user's credentials (e.g., username and password).

• If the credentials are valid, the server creates a JWT containing claims about the user (e.g., user ID, roles), signs it with a secret key, and sends it back to the client.

Token Storage:

• The client (e.g., a web browser) receives the JWT and stores it. Common storage locations include cookies or the browser's local storage.

Token Submission:

• For subsequent requests that require authentication, the client includes the JWT in the request header or as a parameter.

Token Verification:

• The server receives the JWT from the client in each authenticated request.

• The server verifies the integrity of the JWT by checking the signature using the secret key.

• If the signature is valid, the server decodes the claims in the JWT to obtain information about the user.

Expiration and Refresh:

• JWTs can have an expiration time (exp claim), and the server can check if the token is still valid.

• If the token has expired, the client may need to refresh it by re-authenticating with the server.

It's important to consider the following best practices when implementing JWT-based authentication:

• Secure Key Management: Protect the secret key used to sign the JWT. Use strong and unique keys, and store them securely.

• Token Expiration: Set a reasonable expiration time for JWTs to limit their validity period.

• HTTPS: Always use HTTPS to encrypt the communication between the client and server, preventing token interception.

• Token Payload: Avoid storing sensitive information in the token payload. The payload is visible to anyone who can decode the token, although they cannot modify it without knowing the secret key.

• Token Revocation: If a user logs out or if their permissions change, consider having a mechanism for revoking or invalidating tokens.

• Token Refresh: Implement a secure token refresh mechanism to obtain a new token without requiring the user to re-enter credentials.
