| 3 | 1 | Tobias Brunner | Before version:5.0.0 the IKEv1 part of strongSwan was a fork from the discontinued FreeS/WAN project. The keying daemon [[pluto]] had been extended by the strongSwan project in the 2.x series. |

| 5 | 1 | Tobias Brunner | When development of IKEv2 started in 2005, integration of the new protocol into pluto was considered to be too complicated. Therefore a new daemon, [[charon]], was built from scratch. The new daemon is multithreaded and uses object oriented design principles, but is still written in plain C. It's modular design allows customizations through an increasing [[PluginList|number of plugins]]. |

| 7 | 1 | Tobias Brunner | The 4.x releases contained both daemons, which were controlled by the starter daemon and two helper utilities ([[ipsecstroke|stroke]], whack) using distinct UNIX socket interfaces. To share the same UDP ports (IKEv1 and IKEv2 both use ports 500 and 4500) charon used RAW sockets. |

| 9 | 1 | Tobias Brunner | With version:5.0.0 IKEv1 was implemented in charon and pluto and libfreeswan were subsequently removed. With the exception of parts of [[ipsecstarter|starter]] and some crypto plugins no code from the FreeS/WAN project is left in the current strongSwan codebase. |
