Win10 SSH to RPI with key

1.) Create a Key on the RPI and import it

ssh-keygen -b 4096

ssh-copy-id -i .ssh/id_rsa.pub pi@rpi3 

(rpi3 is in this case my Raspberry )

2.) Copy the private key from rpi

([Username] is the windows username)

~/.ssh/id_rsa      to   c:\Users\[Username]\.ssh\id_rsa
~/.ssh/id_rsa.pub  to   c:\Users\[Username]\.ssh\id_rsa.pub

3.) Remove the Keys from the rpi and check if the authorized_keys updated

pi@rpi3:~/.ssh $ rm id_rsa
pi@rpi3:~/.ssh $ rm id_rsa.pub
pi@rpi3:~/.ssh $ ll
total 8
-rw------- 1 pi pi 733 Mar  5 22:15 authorized_keys
-rw-r--r-- 1 pi pi 222 Mar  5 22:15 known_hosts
pi@rpi3:~/.ssh $

4.) Activate ssh_agent in the Windows Services and set it to automatic

 

5.) Start the Agent in Gui or with command net start ssh-agent 

net start ssh-agent 

6.) Import the Key to the agent

 ([Username] is the windows username)

ssh-add c:\Users\[Username]\.ssh\id_rsa_rpi3

7.) To connect without password to the RPI over windows SSH use this command
