SSL/TLS is a cryptographic protocol used to secure communication over computer networks, such as the internet. It provides data encryption, integrity, and authentication between clients (e.g. web browsers) and servers (e.g. websites). This functionality enables it to prevent eavesdropping, tampering, and impersonation attacks. SSL/TLS protocols establish a secure connection through a process of handshake negotiation, where the client and server agree on encryption algorithms, exchange digital certificates, and verify each other’s identities. SSL/TLS is commonly used to secure web browsing, email, file transfer, and other network protocols.
