zmq_z85_encode(3)
=================


NAME
----
zmq_z85_encode - encode a binary key as Z85 printable text


SYNOPSIS
--------
*char *zmq_z85_encode (char *dest, const uint8_t *data, size_t size);*


DESCRIPTION
-----------
The _zmq_z85_encode()_ function shall encode the binary block specified 
by 'data' and 'size' into a string in 'dest'. The size of the binary block
must be divisible by 4. The 'dest' must have sufficient space for size * 1.25 
plus 1 for a null terminator. A 32-byte CURVE key is encoded as 40 ASCII 
characters plus a null terminator.

The encoding shall follow the ZMQ RFC 32 specification.


RETURN VALUE
------------
The _zmq_z85_encode()_ function shall return 'dest' if successful, else it
shall return NULL.


EXAMPLE
-------
.Encoding a CURVE key
----
#include <sodium.h>
uint8_t public_key [32];
uint8_t secret_key [32];
int rc = crypto_box_keypair (public_key, secret_key);
assert (rc == 0);
char encoded [41];
zmq_z85_encode (encoded, public_key, 32);
puts (encoded);
