Encrypts data at the application layer only

Encrypts data at the transport layer and above

The main function of Secure Sockets Layer (SSL) is to encrypt data at the transport layer and above, which ensures secure communication between clients and servers over a network. SSL operates primarily between the transport and application layers, effectively safeguarding data as it travels from one point to another. By using encryption, SSL protects sensitive information from being intercepted and readable by unauthorized parties, making it essential for secure web browsing, online transactions, and other forms of sensitive data exchanges.

While SSL does incorporate features related to authentication and data integrity through digital signatures and certificates, its primary focus remains on encryption, which is critical for protecting data during transmission. Therefore, stating that SSL encrypts data at the transport layer and above accurately reflects its capabilities and role in network security.
