ZMQ_CURVE_PUBLIC(3) 0MQ Manual ZMQ_CURVE_PUBLIC(3) 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 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 (lib- sodium). EXAMPLE Deriving the public key from a CURVE private key. char public_key [41]; char secret_key [41]; int rc = zmq_curve_keypair (public_key, secret_key); assert (rc == 0); char derived_public[41]; rc = zmq_curve_public (derived_public, secret_key); assert (rc == 0); assert (!strcmp (derived_public, public_key)); SEE ALSO zmq_z85_decode(3) zmq_z85_encode(3) zmq_curve_keypair(3) zmq_curve(7) AUTHORS This page was written by the 0MQ community.
