NAME
|
|
----
|
|
zmq_curve_public - derive the public key from a private key
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*int zmq_curve_public (char *z85_public_key, char *z85_secret_key);*
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The _zmq_curve_public()_ function shall derive the public key from a
|
|
private key. The caller provides two buffers, each at least 41 octets
|
|
large. In z85_secret_key the caller shall provide the private key, and
|
|
the function will store the public key in z85_public_key. The keys are
|
|
encoded using linkzmq:zmq_z85_encode[3].
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
The _zmq_curve_public()_ function shall return 0 if successful, else it
|
|
shall return `-1` and set 'errno' to one of the values defined below.
|
|
|
|
|
|
ERRORS
|
|
------
|
|
*ENOTSUP*::
|
|
The libzmq library was not built with cryptographic support (libsodium).
