Encryption
Process of converting readable data (plaintext) into scrambled, unreadable code (ciphertext) that only authorized parties can decrypt. VPNs use encryption to protect your data from interception by ISPs, hackers, and surveillance.
HTTPS
Hypertext Transfer Protocol Secure. Encrypted version of HTTP that protects data between your browser and websites. While HTTPS encrypts website content, it doesn't hide which sites you visit—VPNs provide that additional privacy layer.
OpenVPN
Mature, open-source VPN protocol with proven security through decades of audits. Slower than WireGuard but excellent for firewall bypass using TCP mode on port 443. Gold standard for reliability and compatibility.
