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 translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL)
Cryptography, the science of secret writing, is the biggest, baddest security tool in the application
programmer's arsenal. Cryptography provides three services that are crucial in secure programming.
These include a cryptographic cipher that protects the secrecy of your data; cryptographic certificates,
which prove identity (authentication); and digital signatures, which ensure your data has not been damaged or tampered with
This chapter considers key establishment protocols and related cryptographic techniques
which provide shared secrets between two or more parties, typically for subsequent use
as symmetric keys for a variety of cryptographic purposes including encryption, message
authentication, and entity authentication. The main focus is two-party key establishment,
with the aid of a trusted third party in some cases.
