Re-explain

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that provide secure communication over computer networks. TLS is the successor to SSL, with TLS 1.0 being equivalent to SSL 3.1.

These protocols solve three main security problems:

  • Confidentiality: Data is encrypted so only intended recipients can read it
  • Integrity: Data cannot be modified in transit without detection
  • Authentication: Verification of server (and optionally client) identity

TLS operates between the application layer and transport layer, securing protocols like HTTP (creating HTTPS), SMTP, FTP, and others.
