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.

Protocol

Set of rules governing how data is encrypted and transmitted through VPN. EdgeVPN offers three protocols: WireGuard (fast), OpenVPN (reliable), and V2Ray (censorship-resistant). Each has specific advantages.

WireGuard

Modern VPN protocol with exceptional speed, security, and efficiency. Only ~4,000 lines of code (vs OpenVPN's ~100,000) make it highly auditable. Best protocol for everyday VPN use with minimal speed impact.
