Significant changes since 1.6.0:
* A new -u option instructs spiped to run as a different uid/gid.
* RDRAND x86 CPU extensions (if available) are used as an additional source
of entropy. (Note that they are only used as a *supplemental* source, and
if the operating system provides strong entropy then it doesn't matter if
RDRAND works.)
* SHA x86 CPU extensions (if available) are used to speed up computations.
Few CPUs support these yet.
* spipe now prints a warning if it cannot connect to the target host.
spiped (pronounced "ess-pipe-dee") is a utility for creating
symmetrically encrypted and authenticated pipes between socket
addresses, so that one may connect to one address (e.g., a UNIX socket
on localhost) and transparently have a connection established to another
address (e.g., a UNIX socket on a different system). This is similar to
'ssh -L' functionality, but does not use SSH and requires a pre-shared
symmetric key.
spipe (pronounced "ess-pipe") is a utility which acts as an spiped
protocol client (i.e., connects to an spiped daemon), taking input from
the standard input and writing data read back to the standard output.
