# zmq_curve_keypair(3) Manual Page

## NAME

zmq_curve_keypair - generate a new CURVE keypair

## SYNOPSIS

int zmq_curve_keypair (char *z85_public_key, char *z85_secret_key);

## DESCRIPTION

The zmq_curve_keypair() function shall return a newly generated random keypair consisting of a public key and a secret key. The caller provides two buffers, each at least 41 octets large, in which this method will store the keys. The keys are encoded using zmq_z85_encode(3).

## RETURN VALUE

The zmq_curve_keypair() 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).

## EXAMPLE

Generating a new CURVE keypair

    char public_key [41];
    char secret_key [41];
    int rc = crypto_box_keypair (public_key, secret_key);
    assert (rc == 0);
