How do SSL certificates work with both nginx and postman?

edit

SSL certificates work in a similar way with both nginx and Postman, but the implementation may differ slightly.

With nginx, SSL certificates are typically installed on the server that is hosting the web application. When a user accesses the application through their web browser, a secure connection is established between the browser and the server using HTTPS protocol. The SSL certificate is used to verify that the server is who it claims to be, and to encrypt the data exchanged between the browser and the server to prevent eavesdropping and tampering.

To enable SSL on an nginx server, you first need to obtain an SSL certificate from a trusted certificate authority such as Let's Encrypt or Comodo. This certificate is then installed in the nginx configuration, and the server is configured to use secure HTTPS connections. Users can then access the application using the HTTPS protocol, and their browser will automatically verify the SSL certificate to ensure a secure connection.

With Postman, SSL certificates are used to verify the identity of the web service being accessed. When you send an API request from Postman to a web service, the SSL certificate is used to authenticate that the service is who it claims to be. This is important because it prevents man-in-the-middle attacks and other security threats.

Postman automatically verifies SSL certificates when you send a request, but you may need to configure your SSL certificate settings if you are working with a self-signed certificate or a certificate that is not trusted by default. This can be done in the Postman settings under the "General" tab.

Overall, SSL certificates play a crucial role in securing web applications and API requests, and both nginx and Postman support SSL certificate authentication for enhanced security.
