Linux FreeS/WAN is an implementation of IPSEC & IKE for Linux. IPSEC is Internet Protocol SECurity. It uses strong cryptography to provide both authentication and encryption services. Authentication ensures that packets are from the right sender and have not been altered in transit. Encryption prevents unauthorised reading of packet contents.
tinc is a Virtual Private Network (VPN) daemon that uses tunneling and encryption to create a secure private network between multiple hosts on the Internet. This tunneling allows VPN sites to share information with each other over the Internet without exposing any information.
Pine/SSL adds the ability for Pine to make SSL connections to IMAP, POP, SMTP, or NNTP servers.
The GNU Privacy Guard
GnuPG (the GNU Privacy Guard) is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440. As such, it is meant to be compatible with PGP from NAI, Inc. Because it does not use any patented algorithms, it can be used without any restrictions.
Amrita VPN is an easy-to-use open source VPN solution that runs on the GNU/Linux platform. The implementation is fully in userspace and requires no kernel patches or enhancements. It uses SSL for strong encryption and authentication.
OpenVPN is a robust and highly configurable VPN (Virtual Private Network) daemon which can be used to securely link two or more private networks using an encrypted tunnel over the Internet. OpenVPN's principal strengths include wide cross-platform portability, excellent stability, support for dynamic IP addresses and NAT, adaptive link compression, single TCP/UDP port usage, a modular design that offloads most crypto tasks to the OpenSSL library, and relatively easy installation that in most cases doesn't require a special kernel module.
initscripts-vpn is a "plugin" for Red Hat Linux systems that allows you to easily create secure, encrypted tunnels between routers. It uses SSH for the encryption and PPP for the tunnel. These two pieces of software are almost always installed on any Linux system. The package integrates into Red Hat's initscripts and won't work without it. The modified initscripts-generic package is needed to use initscripts-vpn.
Ginsu Chat Client
Ginsu is a client for the Gale chat system. It is designed to be powerful and above all stable, as well as having a quick learning curve.
RainPortal was designed to secure your private messages while talking on IRC networks. As long as you have RainPortal running and the person you are talking to also, all your private messages will be strongly encrypted while passing on the server.
Coridoras provides a relative simple way to encrypt IRC queries without changing the client and/or the server.
