DNSCrypt Protocol vs OpenVPN

DNSCrypt Protocol

Description: DNSCrypt Protocol is an open standard that encrypts DNS traffic between a DNS client and DNS resolver to help prevent eavesdropping and manipulation of DNS data. It uses cryptographic signatures to verify that responses originate from the chosen DNS resolver.

Type: software

OpenVPN

Description: OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translation (NAT) and firewalls.

Type: software

Pricing: Free
