0MQ 4.3.5                                          03/31/2024                                  ZMQ_Z85_ENCODE(3)

       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.
