This file is part of 0MQ.

|
|
|
This tool generates a keypair for the libzmq CURVE security mechanism,
|
|
and encodes the keypair to give two printable strings that 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.c 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. CURVE is
|
|
defined by http://rfc.zeromq.org/spec:25. Z85 is defined by
|
|
http://rfc.zeromq.org/spec:32.
