A twisted curve is a spiral.
spiral is a collection of elliptic-curve-backed protocol implementations.
At the moment,
this is limited to DNSCurve and CurveCP.
Note:
spiral is still experimental in general;
no guarantees are made about the continued existence of APIs.
DNSCurve support is experimental and requires a currently-unmerged branch of Twisted. Client recursive and nonrecursive resolvers have been implemented; there is currently no DNSCurve server support.
CurveCP support comes in two forms:
curvecpmclient and curvecpmserver are UCSPI-style executables.
curvecpmclient will connect to a given CurveCP server and spawn a process to communicate with it.
curvecpmserver will listen on a particular port and spawn a process for each incoming connection.
Two standard twisted endpoints are exposed for writing clients or servers in python:
CurveCPClientEndpoint and CurveCPServerEndpoint.
