tl;dr: Hyperbeam is roughly a netcat tunnel that connects via a DHT topic instead of network address; use it where you want a secure one-off tunnel. (for example, to transfer a key for Wireguard) Wireguard: + Can tunnel arbitrary IP traffic ~ Has stricter encryption, with full asymmetric keys (and optionally adding a symmetric key) - requires permissions to load a kernel module and configure the network stack Hyperbeam: + Only needs userland UDP sockets, not a kernel module ~ Derives its keys from a passphrase, so does not require transferring a full cryptographic key between devices - is a single application-layer pipe, applicable in shell workflows but not transparently tunneling arbitrary applications
