    Is the transformation that the Conduit uses to ingest string network name and passphrase to generate the corresponding AppEUI and AppKey (for OTAA) documented anywhere?

    Alternately, we could just apply our own hashing and set the Conduit up in EUI/key mode, but we do have some interest in having “named” networks.

    (Net ID = crc64(network_name))

    (Net key = cmac(passphrase, defaultKey))

    The default session key is used with the passphrase as input to the CMAC.
