SKIP Beta2.3 is Released

[Tom Markson <markson@osmosys.incog.com>]

We are pleased to announce the latest release of the SKIP domestic source
reference implementation into the public domain.   This represents a
major release and includes many new features.  It interoperates with 
several other independent SKIP implementations.

Both FreeBSD 2.1.0 and SunOS 4.1.3 are supported in this release.
DES, triple-DES and SAFER are supported for encryption and keyed-MD5 is
supported for authentication.

This source produces a package which contains a loadable module which
works with existing TCP/IP stacks.  You do not need to replace (or even
recompile) your IP stack to use this package.

Source and pre-built binaries (for FreeBSD 2.1.0) may be obtained by US
and Canadian citizens from http://skip.incog.com/

    This software may be used without restriction, for commercial
    and/or non-commercial purposes.
