Creating a SSH Key on a Windows host

1. Open a power-shell window and type the following:

   PS C:\Users\johnt> ssh-keygen -t ed25519 -C "[email protected]"
   

   • This will create a .ssh sub-directory containing the new SSH key

     PS C:\Users\johnt> dir .ssh
     
     
         Directory: C:\Users\johnt\.ssh
     
     
     Mode                 LastWriteTime         Length Name
     ----                 -------------         ------ ----
     -a----          6/4/2023   6:18 PM            419 id_ed25519
     -a----          6/4/2023   6:18 PM            106 id_ed25519.pub
     -a----          6/4/2023   6:20 PM            828 known_hosts     
     -a----          6/4/2023   6:20 PM             92 known_hosts.old
     

     • The id_ed25519 file is the private key. And the the id_ed25519.pub is the public key. Both of these files are text files.
