Misc Studf on SSH

Setup SSH Connection to Raspberry Pi

1. Create Key-Pair

   ╰─ ssh-keygen -t ed25519 -b 4096 -f ~/.ssh/id_ed25519_raspik3s                                                            ─╯
   Generating public/private ed25519 key pair.
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in /Users/volker/.ssh/id_ed25519_raspik3s
   Your public key has been saved in /Users/volker/.ssh/id_ed25519_raspik3s.pub
   The key fingerprint is:
   SHA256:1drFJa2WhxOfQVEYgYFd/sc8JpUWRUK6G235T6MU6P0 volker@MBP-von-Volker.fritz.box
   The key's randomart image is:
   +--[ED25519 256]--+
   |           o.=OXO|
   |          ..o+o=+|
   |          . o +Xo|
   |         . o.+O*o|
   |        S ..+++==|
   |          . .++.o|
   |           ..o .o|
   |            . o.o|
   |             . E.|
   +----[SHA256]-----+
   

2. Copy Public component to target machine

   $> cat ~/.ssh/id_ed25519_raspik3s.pub | ssh pi@raspik3s.fritz.box 'umask 0077; mkdir -p ~/.ssh; cat >> ~/.ssh/authorized_keys'
