libzmq/tools/curve_keygen.c
Pieter Hintjens 576e3ca5e0 Added z85 codec to ZMQ API
* Removed redundant Z85 code and include files from project
* Simplified use of headers in test cases (now they all just use testutil.hpp)
* Export zmq_z85_encode() and zmq_z85_decode() in API
* Added man pages for these two functions

This file is part of 0MQ.
This tool generates a CurveZMQ keypair, as two printable strings you can
use in configuration files or source code. The encoding uses Z85, which
is a base-85 format that is described in 0MQ RFC 32, and which has an
implementation in the z85_codec.h source used by this tool. The keypair
always works with the secret key held by one party and the public key
distributed (securely!) to peers wishing to connect to it.
