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);
