16-byte destination hashes

Every destination is a 16-byte (128-bit) hash shown as 32 hex characters. It comes from truncating a SHA-256 hash of identifying aspects. This size balances address space against packet overhead on low-bandwidth links.

Displayed like <13425ec15b621c1d928589718000d814>
Aspect names can be long. The network only carries the hash
TRUNCATED_HASHLENGTH is 128 bits in the Go cryptography reference

Create a SINGLE destination and print its hash

import RNS

APP_NAME = "example_utilities"

reticulum = RNS.Reticulum(configpath)
identity = RNS.Identity()

destination = RNS.Destination(
    identity,
    RNS.Destination.IN,
    RNS.Destination.SINGLE,
    APP_NAME,
    "minimalsample",
)

destination.set_proof_strategy(RNS.Destination.PROVE_ALL)
destination.announce()
print(RNS.prettyhexrep(destination.hash))
