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.
|
|
|
|
|

.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];
