DevOps Dictionary

OpenVPN is a virtual private network (VPN) system that uses various techniques to establish secure point-to-point or site-to-site connections, supporting both routed and bridged configurations, as well as remote access functionality. It enables peers to authenticate one another using pre-shared secret keys, certificates, or a username and password. In a multi-client server setup, the server issues an authentication certificate to each client using signatures and a certificate authority. OpenVPN uses the OpenSSL encryption library extensively, as well as the TLS protocol, and contains many security and control features.
