.Sh DESCRIPTION
.Nm
is a simple symmetric encryption protocol based on the RC4 stream cipher. Its
goals are both technical and political: it gives reasonably strong protection
of message confidentiality, yet it's designed to be simple enough that even
novice programmers can memorize the algorithm and implement it from scratch.
