The Internet Protocol Security (IPsec) suite is used to implement virtual private networks on FreeBSD and other operating systems. As the networking world continues its transition from 1 to 10, to 40 gigabit per second speeds, and faster, improvements in IPsec’s cryptographic building blocks are necessary to keep pace. The FreeBSD Foundation is pleased to announce that long-time FreeBSD developer John-Mark Gurney is adding modern AES modes to FreeBSD’s cryptographic framework and IPsec. This project is co-sponsored by the FreeBSD Foundation and Netgate, a leading vendor of BSD-based firewalls and networking gear.
