I've just mailed off to Sameer Parekh the January '96 release of the NRL IPv6 sources. For those not in the know, this code implements the IPsec protocol for both IPv4 and IPv6. IPsec is a cryptographic protocol for securing IP datagrams -- it is now an IETF Proposed Standard, defined in RFCs 1825-1829. The code probably could use some work, but its not bad and a reasonable start for all sorts of work. This is a new version that reportedly has lots of bug fixes -- I'm also given the impression it may be the last NRL release of this code because the people doing the work have left there -- if it gets adopted by the BSD community, it will probably end up integrated into future NetBSD, BSDI and FreeBSDs, which would be where to look for future releases. The code should drop into BSDI almost out of the box -- it requires more work for NetBSD and FreeBSD. Perry PS Sorry to interrupt the discussion of the sex life of the Aloe Vera plant with something as irrelevant as cryptography. I can't resist sometimes.
