zmq_curve_public - derive the public key from a private key
int zmq_curve_public (char *z85_public_key, char *z85_secret_key);
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 zmq_z85_encode(3).
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.
