== NAME
zmq_z85_decode - decode a binary key from Z85 printable text
== SYNOPSIS
*uint8_t *zmq_z85_decode (uint8_t *dest, const char *string);*
== DESCRIPTION
The _zmq_z85_decode()_ function shall decode 'string' into 'dest'.
The length of 'string' shall be divisible by 5. 'dest' must be large
enough for the decoded value (0.8 x strlen (string)).
The encoding shall follow the ZMQ RFC 32 specification.
== RETURN VALUE
The _zmq_z85_decode()_ function shall return 'dest' if successful, else it
shall return NULL.
== EXAMPLE
.Decoding a CURVE key
----
const char decoded [] = "rq:rM>}U?@Lns47E1%kR.o@n%FcmmsL/@{H8]yf7";
uint8_t public_key [32];
zmq_z85_decode (public_key, decoded);
