FreeBSD Gets 'Fast IPsec' Implementation
An anonymous reader writes "Sam Leffler (yes, one of the authors of the
BSD Design and Implementation book you have on
your bookshelf if you know anything with operating
systems) has just committed a new FAST_IPSEC
implementation to the FreeBSD 5.x source tree.
It's a merge of the KAME IPsec implementation
and the OpenBSD hardware crypto accelerated
IPsec implementation. You can read the commit message here."
Probably not soon, i think they are avoiding to add it to Linux Kernel to avoid some problems with cryptographic restrictions in some countries. Anyway most distributions include it in their kernels.
