SSL/TLS can be used to protect web applications by providing encryption and authentication to the communication between the client and the server.
Encryption: SSL/TLS uses sophisticated encryption algorithms to make sure that the data transmitted between the client and the server is unreadable to any third party. This prevents hackers from intercepting the data and reading it.
Authentication: SSL/TLS also provides authentication to ensure that the server that the client is communicating with is trustworthy. This is done by using digital certificates and verifying that the certificate is valid and issued by a trusted certificate authority.
In summary, SSL/TLS ensures the confidentiality, integrity, and authenticity of web application communication. It prevents unauthorized access to sensitive information, ensures that the data is not tampered with during transmission, and verifies the identity of the server.
