What do you use to ensure that a Web browser and a web server is a secure Cryptographic connection?

To ensure a secure cryptographic connection between a web browser and a web server, the HTTPS protocol is used, which incorporates SSL/TLS encryption. This protocol encrypts data transmitted between the client and server, preventing eavesdropping and tampering. Additionally, the server presents a digital certificate issued by a trusted Certificate Authority (CA) to authenticate its identity, ensuring users are connecting to the legitimate server. Regular updates and strong cipher suites also contribute to maintaining a secure connection.
