+(net.Dial(), net.Listen(), net.Accept() and net.Conn type) using the
+experimental HerraduraKEx 'secure' key exchange algorithm, first released at
+github.com/Caume/HerraduraKEx
 
-package herradurakex is a simple golang library to manage key exchanges using the algorithm
+One can simply replace calls to net.Dial() with hkex.Dial(), and likewise
-and (TODO) wraps/extends golang.org/pkg/net/, Listener interface, Dial/Accept methods by
+net.Listen() with hkex.Listen(), to obtain connections (hkex.Conn) conforming
-providing a HKexConn built on top of the vanilla Conn.
+to the basic net.Conn interface. Upon Dial(), the HerraduraKEx key exchange
+is initiated (whereby client and server independently derive the same
+keying material) and session algorithms to be used are exchanged allowing an
+encrypted channel between client and server.
 
-Theory:
+NOTE: the terms 'secure' and 'securely' where used above are purposely
-1. Build a standard pkg/net/ Conn c
+enclosed in singled quotes due to the experimental nature of the HerraduraKEx
-2. Build a HKexConn passing in Conn hc (HKexConn implements io.Reader,io.Writer)s
+algorithm used to derive crypto keying material on each end.
-3. Dial/Listen on hc (it will do the KEx and store session key, negotiate crypto alg.)
+As of this time no verdict by acknowledged 'crypto experts' as to the true
-4. Call any pkg/net ops as usual using HKexConn
+security of the HerraduraKEx algorithm for purposes of session key exchange
+over an insecure channel has been rendered.
+It is hoped that such experts in the field will analyze the algorithm and
+determine if it is indeed a suitable one for use in situations where
+Diffie-Hellman key exchange is currently utilized.
