strongSwan

= libstrongswan =
libstrongswan is the foundation library of the IKEv2 keying daemon. It is the base of all newer strongSwan components.

Plugins
libstrongswan itself also supports plugins to provide modular cryptographic algorithms, database support or transport protocol implementations. Each plugin implements the [browser:trunk/src/libstrongswan/plugins/plugin.h plugin_t] interface and registers itself at one of the factories: ||[browser:trunk/src/libstrongswan/credentials/credential_factory.h credentials]||Credential implementations, e.g. certificates or keys.|| ||[browser:trunk/src/libstrongswan/crypto/crypto_factory.h crypto]||Crypto implementations, e.g. encryption algorithms or hashers.|| ||[browser:trunk/src/libstrongswan/database/database_factory.h database]||Database wrappers to access different databases transparently.|| ||[browser:trunk/src/libstrongswan/fetcher/fetcher_manager.h fetcher]||Transport helpers to fetch files, e.g. via HTTP/FTP.|| {{{
