Issue with empty buffer in mount #29

Open pfrazee opened 4 years ago

pfrazee commented 4 years ago

Somehow or other I seem to have accidentally created a mount with a bad key. This causes hyperdrive-daemon to crash with the following error:

Error: key must be a buffer of size crypto_generichash_KEYBYTES_MIN

It's calling discoveryKey() with an empty Buffer, which is why I think I've got a mount with a bad/empty key.
