we are proud to announce our latest strongSwan 4.2.3 release which
can be downloaded from


You might wonder about version 4.2.2 which was never announced
publicly. Due to a GNU autotools configuration problem, the path
to the strongswan.conf file was not resolved correctly, so that
we decided to immediately fix this with the 4.2.3 release.

What's new in 4.2.3?

- Selective loading of plugins

   Plugins for libstrongswan and charon can optionally be loaded
   according to a configuration list defined in strongswan.conf.

   fallback from a hardware crypto accelerator to software-based
   crypto plugins for the case when no HW acceleration is available.
   By default all plugins enabled with configure options during
   compile time are also loaded during run time. An example of a
   load list can be found here:

   SQLite or MySQL database for leases. The "ipsec pool" command helps
   in administrating the pool database. See ipsec pool --help for the
   available options.

   There is also a volatile RAM based "pool-lite" version available:


- Support of authenticated ESP encryption algorithms

   The Authenticated Encryption Algorithms AES-CCM-8/12/16 and
   AES-GCM-8/12/16 for ESP are now supported starting with the
   Linux 2.6.25 kernel. The syntax is e.g. esp=aes128ccm12 or


- 4th IKEv2 Interoperability Workshop in San Antonio, Texas

   We fixed a couple of minor issues that came up while testing
   with IBM, Microsoft, Nokia, SafeNet, SonicWALL and the TAHI project.
