.SH "NAME"
zmq_curve_keypair \- generate a new CURVE keypair
.SH "SYNOPSIS"
.sp
\fBint zmq_curve_keypair (char *z85_public_key, char *z85_secret_key);\fR
.SH "DESCRIPTION"
.sp
The \fIzmq_curve_keypair()\fR 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 \fBzmq_z85_encode\fR(3)\&.
.SH "RETURN VALUE"
.sp
The \fIzmq_curve_keypair()\fR function shall return 0 if successful, else it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
.SH "ERRORS"
.PP
\fBENOTSUP\fR
.RS 4
The libzmq library was not built with cryptographic support (libsodium)\&.
