Cannot upload ssh key to my Droplet from Windows OS and keep getting "permission denied (publickey)" error
I have two computers, one OS Mac and one OS Windows. Using the Mac i managed to add the SSH public key and I can log into the droplet from the local machine terminal.
On the one using windows, however, everytime I try to log in it throws the error
“permission denied (publickey)”.
I tried to follow the tutorials:
Still, I cannot get through it.
For example, in the session https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/to-existing-droplet/#manually
it says to paste the key with nano editor but when I try to paste it, some characters of the key are changed (encrypted?) and I do not want to manually copy and paste the key inside the text editor.
Also, I do not have in my local machine this file “cat ~/.ssh/id_rsa.pub”. Is it simply referring to the Putty key saved as private after the creation which I already added to the account (but not to the droplet)?
Also, even from the droplet web console when I try to use the “ssh” command it throws the error “permission denied (publickey)” so I cannot really do anything.
What am I doing wrong? Where can I find a working tutorial?
Thanks in advance for the answers.
