My bad, it is the enc(4) interface:
https://man.openbsd.org/enc.4
# ifconfig enc0
enc0: flags=0<>
index 2 priority 0 llprio 3
groups: enc
status: active
# tcpdump -i enc0
tcpdump:

That depends on OS/configuration. There could be literally "ipsec"
interface in FreeBSD to see exactly the packets flowing over that VPN

You can also find that protocol in almost any 'hardware' router
that claims to support a VPN: Mikrotik, StormShield, Forti

Various. Mostly either PSK (symmetric pre-shared key) or

Are you aware that "just encryption" is practically useless, if it does
not authenticate transmitted data somehow? By MAC, by AEAD, by signature,
but with "just encryption" malefactor in many cases can alter your data

Generally no asymmetric encryption is used in modern protocols.
Only signing and key exchange operations as a

Pay attention that using asymmetric cryptography is pretty CPU consuming
task. Using it for each IP pac

Dear devs,
Currently, all phones use WiFi, GSM, Bluetooth networks in practically all
applications. For WiFi and Bluetooth replacements, do you have any alternate
network in mind which caters to only local public and private keys.
So, a network which before transmitting a packet, encrypts it wi
