This is a drop-in replacement for the golang/pkg/net facilities
|
|
(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
|
|
|
|
One can simply replace calls to net.Dial() with hkex.Dial(), and likewise
|
|
net.Listen() with hkex.Listen(), to obtain connections (hkex.Conn) conforming
|
|
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.
|
|
|
|
NOTE: the terms 'secure' and 'securely' where used above are purposely
|
|
enclosed in singled quotes due to the experimental nature of the HerraduraKEx
|
|
algorithm used to derive crypto keying material on each end.
|
|
As of this time no verdict by acknowledged 'crypto experts' as to the true
|
|
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.
