OpenVPN - свободная реализация технологии виртуальной частной сети (VPN) с открытым исходным кодом для создания зашифрованных каналов типа точка-точка или сервер-клиенты между компьютерами. Она позволяет устанавливать соединения между компьютерами, находящимися за NAT и сетевым экраном, без необходимости изменения их настроек. OpenVPN была создана Джеймсом Йонаном (James Yonan) и распространяется под лицензией GNU GPL

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[9] 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).[10]

OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and certificate authority. It uses the OpenSSL encryption library extensively, as well as the TLS protocol, and contains many security and control features.

OpenVPN has been ported and embedded to several systems. For example, DD-WRT has the OpenVPN server function. SoftEther VPN, a multi-protocol VPN server, has an implementation of OpenVPN protocol.

После двух с половиной лет с момента публикации ветки 2.5 подготовлен релиз OpenVPN 2.6.0, пакета для создания виртуальных частных сетей, позволяющего организовать шифрованное соединение между двумя клиентскими машинами или обеспечить работу централизованного VPN-сервера для одновременной работы нескольких клиентов. Код OpenVPN распространяется под лицензией GPLv2, готовые бинарные пакеты формируются для Debian, Ubuntu, CentOS, RHEL и Windows.

Openvpn_2.5.7 Repack

Dynamic TLS Crypt: When both peers are OpenVPN 2.6.1+, OpenVPN will dynamically create a tls-crypt key that is used for renegotiation. This ensure that only the previously authenticated peer can do trigger renegotiation and complete renegotiations.
CryptoAPI (Windows): support issuer name as a selector. Certificate selection string can now specify a partial issuer name string as "--cryptoapicert ISSUER:<string>" where <string> is matched as a substring of the issuer (CA) name in the certificate.




--------------------

This is mostly a bugfix release with some improvements.

User visible changes:
OCC exit messages are now logged more visibly See GH ​#391.
OpenSSL error messages are now logged with more details (for example, when loading a provider fails, which .so was tried, and why did it fail) See GH ​#361.
print a more user-friendly message when tls-crypt-v2 client auth fails
packaging now includes all documentation in the source tarball
New features:
set WINS server via interactive service - this adds support for "dhcp-option WINS 192.0.2.1" for DCO + wintun interfaces where no DHCP server is used. See GH ​#373.
